Most people treat Chumphon as a pass-through on the way down to Koh Tao and Samui, and just blow right past it. But if you can spare an extra day or two, starting with one night in Chumphon and then crossing into Surat Thani lets a single trip catch both Chumphon's food and the highlights of Surat Thani. The two provinces sit side by side on the southern rail line and Phetkasem Road, so it's easy to carry on from one to the other. Once you reach Surat Thani you choose between the mountain-and-lake side at Cheow Lan, or the sea side at Koh Samui. This plan lays out both routes so you can picture them — pick one, or link the two together.
The route overview before you set off
Chumphon and Surat Thani are about 190 kilometres apart, linked by the southern rail line or by van, taking roughly 2.5 to 3 hours. Once you reach Surat Thani, if you're heading to Cheow Lan Lake in Khao Sok National Park, aim for Ban Ta Khun district, about 1.5 hours from the city. If you're heading to Koh Samui, go to Don Sak pier and take the ferry across, about 1.5 hours. These two spots are in different directions, so picking one first makes planning much easier.
Why start in Chumphon and head down to Surat Thani after
If you're coming from Bangkok on the overnight train or a coach, Chumphon is the first big town you reach before Surat Thani, so stopping for one night there lands at just the right point. You get to rest off the overnight journey, eat fresh seafood from the small fishing boats at the Pak Nam estuary, and try the robusta coffee that Chumphon grows so much of it's become one of the country's main sources. The next morning it's only another two and a half hours by road to Surat Thani, and you'll still have energy for the whole day — better than pushing straight through in one long haul until you're worn out.
- It paces the journey — Chumphon is a stopover before Surat Thani, so you don't have to sit through one long unbroken ride.
- Two towns of food — seafood and robusta coffee in Chumphon, then southern khanom jeen with curry sauce in Surat Thani.
- Pick your endpoint — from Surat Thani you split off to the mountain lake at Cheow Lan, or the sea at Koh Samui.
- Flexible on time — works as a 3-day, 2-night trip, or stretches to 4 days if you want to sleep on both the raft and the island.

How to get from Chumphon to Surat Thani
Chumphon and Surat Thani are linked by both the southern rail line and Phetkasem Road, so there are three main ways to do it depending on budget and time. The train makes for easy scenery but timing depends on the schedule; vans run more often and are faster; driving yourself is the most flexible if you're carrying on to Cheow Lan Lake, which sits outside the city.
- Southern line train — tickets start at around a hundred-plus THB per trip, taking roughly 2.5 to 3 hours, dropping you at Surat Thani station in Phun Phin district, about 13 kilometres from the city.
- Van / minivan — runs frequently all day from central Chumphon, fares in the low hundreds of THB, taking around 2.5 hours, and dropping you right in central Surat Thani.
- Drive yourself — straight down Phetkasem Road, about 190 kilometres, taking around 2.5 to 3 hours, ideal if you're going on to Cheow Lan Lake or Don Sak pier, both outside the city.
The train station isn't in the city
Surat Thani railway station is in Phun Phin district, about 13 kilometres from the city. If you get off the train and want to reach the centre, you'll have to transfer to a songthaew or van. The upside is that Phun Phin sits right on the route toward Ban Ta Khun and Cheow Lan Lake, so if you're heading straight to the lake you don't have to detour into the city. For Koh Samui, though, Don Sak pier is in the other direction — you'll need to carry on east for about another hour.
Route A — Sleep on a floating raft on Cheow Lan Lake, Khao Sok
Cheow Lan Lake, or Ratchaprapha Dam, inside Khao Sok National Park, is a lake set among limestone peaks that many people call the Guilin of Thailand. The water is emerald green, with rock mountains rising in a line out of the lake. The draw is sleeping on a floating raft and waking to a sea of mist drifting over the water in the morning — an experience that's hard to find elsewhere. It suits a trip where you want quiet nature rather than a busy beach scene.

What to know about rafts and prices
Cheow Lan Lake has both national park rafts, in the low hundreds to low thousands of THB a night and kept simple, and private rafts sold as packages that include the transfer boat and meals. The well-known private operators like 500 Rai are the furthest out, about 25 kilometres of boat ride in; a relaxed 2-day, 1-night package starts around 3,900 THB per person, while an activity-focused one runs from about 5,900 THB up. There are both air-con and fan rooms, with prices varying by distance and facilities. Book ahead, because the good rafts fill up fast on holidays, and always check the latest price with the operator first.
Route B — Take the ferry from Don Sak across to Koh Samui
If you want sea over mountains, Surat Thani is the gateway up to Koh Samui, Koh Phangan and Koh Tao on this side. The main pier for Samui is Don Sak pier, on the eastern side of the province, served by the two big ferry operators — Seatran and Raja Ferry — running back to back almost all day. A ferry is more comfortable than a speedboat, with less wave slam, and it can carry your car across too if you drove yourself.

Don Sak to Samui ferry: times and prices
Both Seatran and Raja Ferry run Don Sak to Samui from early morning to evening. Raja's first sailing is around 05:00 and the last around 19:00, while Seatran runs hourly through the middle of the day. The crossing takes about 1.5 hours. Foot-passenger fares are in the low hundreds of THB per trip; if you bring a car it costs more by vehicle size. Check the latest sailings and prices with the ferry company before you travel, as the timetable shifts with the season and holidays.
What to eat along the way across the two provinces
The food is the bonus of a cross-province trip like this — you get both Chumphon and Surat Thani flavours in one go. The list below is ordered by where you'd likely stop along the plan, not by which place outranks another. Many of them sit right on the route, so check days off and opening hours again before you go to be sure.
Krua Jae Ang, Pak Nam Chumphon
A roadside seafood spot out by the Pak Nam estuary in Chumphon, with ingredients fresh off the small fishing boats. Lots of standout dishes — fried fish, sour curry, and spicy salads — making it a tidy first-night dinner before you move on.
Robusta Station, Chumphon
A minimalist cafe on Phetkasem Road serving well-selected Chumphon robusta. There are local goods too — roasted coffee and dried products — to grab for the road.
Southern rice-and-curry shops in central Chumphon
Punchy southern rice-and-curry stalls in the markets and along the streets in town — gaeng leuang, khua kling, stir-fried pak liang with egg, at friendly prices. Good for a quick lunch on day one before you rest.
Khanom jeen with crab curry sauce, Surat Thani
Soft khanom jeen noodles under a rich southern-style crab curry sauce, eaten with fresh vegetables, in central Surat Thani. There are several well-known shops around the market and the bypass road — a late-morning meal with real local flavour before the boat to the island or the lake.
Khanom Jeen Baan Mae, Surat Thani
A khanom jeen shop on the bypass road with several curry sauces to choose from, eaten with hot crispy fried chicken — a local favourite that's easy to drop by on the way through.
Krua Nithitham, Surat Thani
A seafood restaurant in central Surat Thani with ingredients fresh from farms and local boats. Standouts include prawn cakes, big oysters, and cockles — good for lunch or dinner if you stay a night in the city.
Wire Cafe, Surat Thani
A cafe in central Surat Thani done in a modern loft style, warm-toned, airy, with natural light in every corner. A good place to stop for a coffee while you wait for onward transport to the pier or the lake.
Eateries near the Cheow Lan Lake pier
Around the Cheow Lan Lake pier in Ban Ta Khun there are made-to-order and rice-and-curry shops, good for a lunch to line your stomach before boarding for the raft. Expect freshwater fish and local southern dishes.
Meals on the Cheow Lan rafts
Most raft stays include meals in the package, served as homestyle dishes — steamed and fried fish out in the middle of the lake. Eating waterside ringed by mountains is one of the real pleasures of a raft stay.
Seaside seafood at Chaweng beach, Koh Samui
If you take the Samui route, Chaweng beach has seaside seafood spots to sit and eat in the evening breeze — grilled fish, prawns and squid. Island prices run higher than the mainland, but the sea view and setting make it worth it for a first meal on the island.
Which route — Cheow Lan Lake or Koh Samui?
These two routes feel completely different. If your time is tight, pick one and do it properly rather than running both and wearing yourself out. Compare them simply below, then choose by the kind of atmosphere you want from this trip.
Route A: Cheow Lan Lake
Rock peaks rising from a green lake, quiet raft stays, waking to a sea of mist. Good for those who want a real break, time with nature, phone signal cut off, and no busy beach scene.
Route B: Koh Samui
The Gulf of Thailand, white sand beaches, restaurants, cafes and bars all there. Good for those who want an island with full facilities — swimming, diving, and nightlife.
How to travel and pack to keep it smooth
A cross-province trip like this has several bus and boat transfers, so ordering them well saves you from rushing around. The trick is to check train and ferry schedules ahead, and pick accommodation close to each transfer point.
- Book ahead — train tickets, Cheow Lan rafts and Samui accommodation fill up fast over long holidays, so booking early pays off.
- Allow transfer time — the train station is in Phun Phin and Don Sak pier is outside the city, so build in time to move around in town too.
- Pack for the boat — motion-sickness pills, a windbreaker, and a waterproof phone bag work for both the raft and the ferry routes.
- Cash — some rafts and local shops mainly take cash, so carry small bills.
- Check the season — late in the year is monsoon season on the Gulf side and ferries can be affected, so have a backup plan.
