At a Glance
- We’ve visited Thailand 8 times over the past 20+ years – most recently for 3.5 months over two stints in 2026. This was the first time we’d explored this Bangkok to Koh Lanta route.
- Total journey: Bangkok to Koh Lanta – approximately 900km
- Recommended approach: Train Bangkok to Hua Hin, stay a few days, collect hire car, drive south over 4 days
- Total driving distance (Hua Hin to Koh Lanta ferry): approximately 780km
- Total driving time without stops: around 10 hours (we broke up over 4 days)
- Best time to travel: November to April – dry season on both coasts
- Why train not drive from Bangkok: Bangkok traffic is brutal and we just didn’t fancy it – the train can be faster than the car or bus, cheaper and probably far less stressful unless you’re a pro at driving in Thailand/Bangkok.
- End point: Koh Lanta car ferry pier near Krabi
- Highlights en route: Hua Hin, Phraya Nakhon Cave, Thung Wua Laen beach, the karst scenery of Krabi Province
Bangkok to Koh Lanta: Your Options at a Glance
Koh Lanta has no airport and no bridge to the mainland, so every route ends with a minivan and a car ferry or two. Which one suits you depends on how much you value time, money and scenery. Times and prices are approximate and change with the season, so check before you book.
| Option | Total time | Rough cost per person | Best for |
|---|---|---|---|
| Fly to Krabi, then minivan | 4 to 5 hours | From about 2,000 THB+ | Speed |
| Sleeper train to Trang, then minivan | About 16 hours incl van | From about 800 THB | Kids who sleep on trains |
| Overnight bus or minivan | 15 to 18 hours | About 1,100 to 1,500 THB | Tightest budget. Resilient kids! |
| Train to Hua Hin and a hire car (this guide) | 4 days+ | Car hire plus fuel and stays | Scenery, stops, flexibility, family fun |
Flying to Krabi is the quickest. Budget airlines fly from both Bangkok airports to Krabi in around 1.5 hours. Koh Lanta is about 60km from the airport, and a minivan takes you straight to your hotel on the island, including the car ferry. Watch the baggage allowances on the cheaper airlines, as family luggage adds up quickly.
The sleeper train runs overnight to Trang and takes about 13 hours. From there a minivan takes a few hours to the island. Sleepers sell out, especially from December to February, so book well ahead. Check which Bangkok station your train leaves from when you book.
The overnight bus leaves Bangkok in the evening, usually from the Southern Bus Terminal, and arrives in the morning. You can book a direct service to Koh Lanta or a bus to Krabi and a minivan on from there. It’s the cheapest option, but with kids it’s a long night and delays are common – not recommended.
The road trip is what the rest of this guide covers: the train to Hua Hin, a hire car, and four days of driving south with stops along the way. It’s the slowest option, but it’s the only one where the journey is part of the trip, and it’s what we decided to do, and thoroughly enjoyed it.
For a family in a hurry, my pick would be flying to Krabi. If you have the time, the road trip below is the one worth doing – it really opened up this part of the country to us.
There is no quick way to get from Bangkok to Koh Lanta: the island has no airport or bridge, so every route ends with a minivan and one or two car ferries
Most people fly to Krabi and are on the island by lunchtime by doing so.
We took the long way round: a train to Hua Hin to dodge Bangkok traffic, a hire car, and four days heading south with stops along the way, watching the limestone karsts of Krabi Province appear as we got closer.
It was far slower, but a lot more rewarding. This guide covers that route step by step, including the train, the hire car, the best stops and where to stay.

Why Take the Train from Bangkok Rather Than Driving?
Bangkok traffic is, by any objective measure, one of the great miseries of Southeast Asian travel. On a bad day, the drive out of the capital heading south can add a couple of hours to your journey before you’ve even left the city limits, subject to where you start your journey. With kids in the back asking why nothing is moving, this is nobody’s idea of a holiday start.
The train from Bangkok’s Hua Lamphong or Bang Sue station to Hua Hin takes around three hours and deposits you 200km south of the capital without a single traffic jam. It’s cheap, comfortable, and the kids can move around rather than being strapped into car seats in gridlock.
From Hua Hin you can spend a few days (or a couple of months as we did), collect your hire car (best pre-booked in advance for a one-way return in Krabi), and the road south opens up in front of you with the worst of the Bangkok sprawl already behind you.
The honest calculation: Bangkok to Hua Hin by train is cheap and removes the stress of driving it. Hua Hin to Koh Lanta is where the interesting driving is. Do the boring bit by train and the good bit by car.
Step 1: Bangkok to Hua Hin by Train
Trains run regularly from Bangkok to Hua Hin throughout the day. The journey takes approximately 3 to 3.5 hours depending on the service.
Which Station in Bangkok?
Trains to Hua Hin depart from both Hua Lamphong (the old central station in the city centre) and Bang Sue Grand Station (the newer main terminal in the north of the city). Check which station your specific service departs from when booking. We went from Bang Sue Grand Station, which when we were there, was relatively empty.
Which Train to Take?
- Rapid and Express trains are the most comfortable and reliable with air conditioned carriages – we booked 2nd class with aircon. Seats were comfortable and spacious.
- Ordinary trains and lower classes are cheaper but slower and less comfortable for families and unlikely to have aircon.
- Book in advance during peak season (December to February) – trains do fill up
- Second class air-conditioned carriages are perfectly comfortable for a 3-hour journey and considerably cheaper than first class, which for the length of journey is sufficient.
Stop: Hua Hin - Worth More Than One Night
We would recommend not just collecting your car and driving off. Hua Hin is fantastic for families, and we ended up staying two months.
Hua Hin is one of the best family destinations in Thailand – a proper beach town with heaps of activities, excellent food, several night markets and enough going on to keep kids genuinely entertained for weeks. We based ourselves there for two months and still left some for next time.
If your schedule allows, it’s best to leave yourself at least 2 or 3 days in Hua Hin before continuing south. You won’t regret it.

We stayed at Baan Kiang Fah in the south of the city. A great spot with incredible sea views, a nearby market, bars and cafes, walking distance to the central shopping malls and the beach. The place had a gym and pool. We paid 1,000THB / USD$30 per night.
Book at Baan Kiang Fah here.
Book other accommodation in Hua Hin here.
Our favourite place to eat was Im Jang, a family run restaurant almost next door to our accommodation where we rarely paid more than 200-300THB for the four of us for mind blowing food.
Step 2: Picking Up Your Hire Car in Hua Hin
Pre-book your hire car in Hua Hin before you travel – don’t turn up and hope. Car hire availability in Hua Hin can be limited, particularly in peak season, and you want a one-way rental arranged in advance with the drop-off confirmed in Krabi, which can be a little trickier to organise.
One-Way Rental Tips
- Confirm one-way drop-off is permitted and what the fee is before booking – it varies significantly between companies. We booked through Trip.com here
- Book automatic rather than manual – easier for long drives
- Ensure air conditioning works – non-negotiable on this route
- Don’t forget your International Driving Licence – essential for car hire in Thailand
- Take photos and videos of any existing damage before you drive away

Day 1 of the Drive: Hua Hin South to Sam Roi Yot Beach
We left Hua Hin mid-morning and drove just a short one-hour drive to Sam Roi Yot Beach, where we stayed for the night. We didn’t travel far as we wanted to visit Phraya Nakhon Cave early on Day 2.
Sam Roi Yot Beach is a tiny quiet village right on the beach with just a small scattering of cafes, hardly any tourists and a few places to stay.
The beach is huge and whilst the sea was a bit choppy when we were there, the beach was nice enough for a long walk.
We stayed at Pineapple Resort – a very basic cheap place, just a few minutes’ walk from the beach, for 470THB/USD$14 for the night with all four of us in one giant bed!
Book accommodation in Sam Roi Yot here.
We ate at a local place located on a crab farm off the main road surrounded by limestone cliffs. We found it on Google – it has no western name, so just search for “ครัวคุณจ้อย” – food was great, costing just 230THB for the four of us, in a great setting, as we watched the sun go down.
Day 2 of the Drive: AM: Visit Phraya Nakhon Cave and then drive to Thung Wua Laen Beach
From Sam Roi Yot Beach, it’s an easy short 15-minute drive to one of the most genuinely spectacular things we saw in the whole of Thailand – visiting Phraya Nakhon Cave, located in Khao Sam Roi Yot National Park.
There’s ample parking at the Cave car park and there’s several places to eat and buy drinks.
Phraya Nakhon Cave itself sits on a hillside above the Gulf coast.
There are two ways to get to the Cave stairway, the starting point.
One is a steep 45-minute walk up steps and across the cliff edge and back down to a beach, which leads to the Cave entrance/steps.
Or you can pay extra for a short boat crossing to the beach and skip the 30-minute walk.
Then starts the steps to the cave entrance, which is a very steep path through the jungle. The path is well marked but it is hard work so bring water and wear decent shoes.
Our kids aged 9 and 7 made both climbs. They’re steep but safe.
After a 30-minute tiring climb, you finally get to the inside of the cave where you find the Royal Pavilion – a ceremonial structure built around 150 years ago for the Thai Royal Family. Extraordinary in itself. But what makes Phraya Nakhon Cave truly unforgettable is the light.
The cave roof has partially collapsed. At around 10-11am on a sunny morning, the sun shines through the gap and floods the golden pavilion from above in a shaft of natural light that makes the whole structure glow like something supernatural. Like an angelic building being birthed from the rock.
Truly one of Thailand’s top attractions and one that most visitors driving this route miss entirely by taking the direct highway.
To come back, you do the same hike in reverse.
Practical tips:
- Aim to be at the cave between 10am and 11am for the light – earlier or later and you miss the magic
- Start the hike early – it takes 45 minutes for the first steep 500m section and then another 30 minutes once in the cave section – 400m climb.
- Boat from the beach to the trailhead: 400THB each way – up to six per boat
- National Park entrance fee: 200 THB adults / 100 THB kids
- There is a café between the two sections of the hike, by the beach. We stopped on the way back. It’s a little pricey but decent enough.
- Toilets are by the café by the beach. No toilets once you started the second climb into the cave so best go before you set off.
Day 2 PM: Driving further south after the cave to Thung Wua Laen Beach (near Chumphon)
After the cave comes the first proper long journey although the driving is relatively straightforward – flat, well-maintained roads, with the sea occasionally visible on your left. You’ll pass a few small towns but nothing challenging.
You decide to stop anywhere on the coast but you’ll need to do at least 3 hours to bite a decent chunk of the journey off.
After 45 minutes, we stopped for food at a complete random restaurant in a tiny village we were passing through, called Kui Nuea.
From there, it was a 2-and-a-half-hour drive to our next accommodation at Thung Wua Laen Beach.
And what a spot that was.
Incredibly laid back small little town with a string of cafes and bars located right on the beach. I even managed to squeeze in a massage to soothe my poor little legs after the steep climb at the cave.
The beach was incredible – beautiful white sand and the sea crystal clear. Friendly locals and just a great spot to unwind for an afternoon and next morning.
We stayed at Albatross Guesthouse, just a few minutes’ walk away from the beach, getting two simple clean (no aircon but fan) double rooms costing 370 THB / USD$11 each.
Book here for the Albatross Guesthouse
Book here for other accommodation in Thung Wua Laen.
We fancied Western Food at night, so headed to MD Pizza Café for pizzas, totalling 640 THB.
Day 3: South Through Surat Thani, heading inland
We had an awesome breakfast in Thung Wua Laen Beach at Pirates Terrace, again going for the Western option of a Fried Breakfast at 180THB.
Finding it hard to pull ourselves away from the lovely beach, we headed off further south around lunchtime, after I squeezed in that much needed massage.
We drove for 3 hours down to Surat Thani but rather than stay in the city, we decided to stay right by the main road that was to take us inland towards Koh Lanta.
We stayed at a motel style place called Bali Boutique for 850THB / USD$25 (+ additional 50THB for breakfast) – with all four of us in one room. The room was decent with aircon and TV. They have a café on site, so we had dinner from there.
Book here for the Bali Boutique Hotel

Day 4: Into Krabi Province and onto Koh Lanta
The breakfast was basic but decent enough to fill us up for our journey ahead – chicken rice porridge, toast and boiled eggs – although the kids turned their noses up at the rice porridge, with a look of “where’s the cereal dad?”.
With nothing else to see in the area, we set off early.
Day four is when the drive becomes something else entirely.
As the road swings from the Gulf of Thailand side of the peninsula to the Andaman Sea side, the scenery changes dramatically. The flat coastal plains give way to jungle-clad hills, and then, as you enter Krabi Province, the limestone karsts begin.
These are the formations that make Phang Nga Bay world famous. Towers of ancient rock rising vertically from the ground and sea, covered in jungle, sometimes hundreds of metres tall. They start appearing one at a time on the horizon. Then in pairs. Then in clusters. Then the road is running through them.
This is the moment where I found myself doing what the kids had been doing to me for the previous two days.
‘Wooooow.’
Constantly. Every few kilometres, another one.
The kids were, by this point, less impressed. They’d been promised a beach. Rocks are rocks. But the adults in the car were transfixed.
Krabi Town – Optional Stop
After blasting it with no traffic in sight down Route 44, we arrived on the outskirts of Krabi Town in an hour.
Krabi Town is the main hub of the province – a pleasant riverside town with a decent night market and a good base if you want to explore the area. Worth a stop for fuel, food and supplies before the final leg to the ferry. We spent a couple of hours getting provisions, having read that things were more expensive on Koh Lanta.
The Koh Lanta Car Ferry
Another hour from Krabi and we reached the Koh Lanta car ferry around 1pm.
The ferry is a ten-minute hop across a narrow strait that somehow marks a complete change of atmosphere. The ferry runs throughout the day, no booking required – queue and board.
We have a full guide to this crossing including exactly where to find the pier, timings, cost and what to expect on arrival on the island.

After ten minutes, you’ve made it – welcome to Koh Lanta
📍 Where We Stayed on Koh Lanta: Patcharin House
A spacious, clean, 2-bedroom villa, located just a 5-minute walk to Khlong Noen Beach, with its many bars and restaurants, in a quiet area by the main road. Cows walk by the back door. It has a fully equipped kitchen, decent bathroom and a huge living space – perfect for the kids to play.
Tips for Doing This Journey with Kids
- Take the train from Bangkok – we personally didn’t fancy driving in and out of Bangkok
- Book train tickets in advance – second class air-conditioned is comfortable and affordable
- Collect your hire car in Hua Hin – simple, cheap, avoids big city driving (book here)
- Break driving days into 3-5 hours segments and allow for stops with kids
- Time your Phraya Nakhon Cave visit for 10-11am for the light show – this is a must so plan the rest of the day around this. It’s why we left Hua Hin the day before and not in the AM.

Frequently Asked Questions
Q: How do you get from Bangkok to Koh Lanta with kids?
A: The fastest way is to fly from Bangkok to Krabi, which takes about 1.5 hours, then take a minivan to the island. Door to door that’s around 4 to 5 hours. The cheaper options are an overnight sleeper train to Trang or an overnight bus, which both take 15 hours or more. Whichever you choose, the last stretch is a minivan or car and a short car ferry, as Koh Lanta has no airport and no bridge.
The route we cover in this guide takes longer but is far more interesting. Take the train from Bangkok to Hua Hin, hire a car there, and drive south over four days, with stops at Sam Roi Yot, Phraya Nakhon Cave and Surat Thani before the ferry.
Q: Why take the train from Bangkok rather than driving?
A: Bangkok traffic can be severe and could add more hours onto your journey. The train covers the Bangkok to Hua Hin leg in around 3 hours comfortably and cheaply, with no traffic jams, no navigation stress, and the ability for kids to move around. From Hua Hin the interesting driving begins – pick up your hire car there instead.
Q: How long does the drive from Hua Hin to Koh Lanta take?
A: Around 10 hours of total driving time without stops – approximately 780km – practically impossible with young kids, as they will need to break up the journey.
We strongly recommend breaking it into 4 days (or more if you have time) to allow for stops at Phraya Nakhon Cave and beaches along the way, and to avoid exhausting driving days with children.
Q: Is Phraya Nakhon Cave worth visiting?
A: Without question – it was one of the most spectacular things we saw in all of Thailand. A Royal Pavilion inside a jungle cave, lit by a shaft of natural sunlight through a collapsed roof at around 10-11am. The hike is steep and hot but absolutely worth the effort. Don’t drive past it. Despite what you might hear, in our opinion and experience, it was fine for kids. Challenging yes, but totally doable. Our 9- and 7-year-old did it.
Q: Do I need a hire car for this route?
A: Yes – from Hua Hin onwards the stops along the way are not easily accessible by public transport. There is a train line that runs down the Gulf Coast but a car gives flexibility of stopping off at random places – much better when travelling with kids. Book a one-way hire car in Hua Hin with drop-off in Krabi in advance. Check the one-way fee carefully before booking as it varies between companies.
Q: Is this route suitable for families with young children?
A: Yes with the right planning. Take the train for the Bangkok leg. Break the driving into short days of 3-5 hours maximum. Plan the Phraya Nakhon Cave visit for early to mid-morning. Keep snacks and activities in the car. The hike to Phraya Nakhon Cave is suitable for older children (7+) but may be challenging for very young kids – factor this in when planning although we had friends who did it with three kids, all under 5!
Q: Where should I stop overnight between Hua Hin and Koh Lanta?
A: Night one near Sam Roi Yot or Pranburi – puts you close to Phraya Nakhon Cave for an early morning visit. Night two in the Chumphon area after a beach stop at Thung Wua Laen. Night three somewhere in the Surat Thani region, giving you plenty of time on Day 4 to get to the Koh Lanta ferry and onto Koh Lanta. Optional stop in Krabi.
Q: How much does it cost to get from Bangkok to Koh Lanta?
A: The cheapest combined flight and minivan starts from about 2,000+ THB per person. A sleeper train and minivan starts from about 800 THB, and an overnight bus costs around 1,100 to 1,500 THB. The road trip costs depend on car hire, fuel and where you stay. Prices change with the season, so check before booking. We found accommodation cheap and plenty of cheap places to eat so whilst the road trip may take longer, it may not cost much more than a flight and the experience is far more fun.
Q: Is there a direct train from Bangkok to Koh Lanta?
A: No, as Koh Lanta is an island with no railway. The usual route is an overnight sleeper train to Trang, followed by a minivan to the island that takes a few hours. Sleepers sell out in the busy months, so book early.
