Chumphon is one of Thailand’s most useful gateways to the Gulf islands, particularly for travelers arriving by train from Bangkok or continuing south from the mainland. Although there is no railway connection to Koh Samui, the journey is straightforward: travel to Chumphon by train, bus, or flight, then continue by road and high-speed catamaran.
For most travelers, the easiest option is a combined minivan or bus + ferry ticket. Lomprayah is the main operator on the Chumphon–Koh Samui route, while Boonsiri also operates services on the Gulf network. Current 2026 schedules show daily Lomprayah services from Chumphon to Koh Samui, with journey times of roughly 4 hours 15 minutes to 5 hours 30 minutes depending on the sailing and destination pier.
Chumphon to Koh Samui at a glance
| Route | Approx. journey time | Typical price | Best for |
|---|---|---|---|
| Chumphon train station → Koh Samui | 5–6 hours | Around THB 1,260–1,500 | Travelers arriving by train |
| Chumphon town → Koh Samui | Around 5–6 hours | Around THB 1,200–1,500 | Travelers already staying in Chumphon |
| Chumphon pier → Koh Samui | Around 4–5.5 hours | Around THB 960–1,200 | Independent travelers |
| Bangkok → Chumphon by train + ferry | Around 12–16 hours | Varies by train class + ferry | Budget travelers |
| Bangkok → Koh Samui by air | Around 1 hour 15 minutes flying time | Usually considerably more | Travelers prioritising speed |
Prices are indicative rather than fixed. Fares vary according to the departure point, destination pier, transfer arrangements and travel date. Always check the current operator timetable before departure. Lomprayah publishes its 2026 timetable and booking information on its official website.
The easiest option: Chumphon train station to Koh Samui
For travelers arriving in Chumphon on the Southern Railway Line, the simplest arrangement is a combined train-station transfer + catamaran ticket.
The process is:
Chumphon Railway Station → minivan/bus → Chumphon pier → high-speed catamaran → Koh Samui
The road transfer connects the railway station with the ferry departure point, so passengers do not need to arrange a separate taxi to the pier.
Current schedules show Lomprayah services connecting Chumphon with Koh Samui. One published timetable for late August and early September 2026 lists a 05:45 departure from Chumphon Lomprayah Pier arriving at Bangrak Pier at 11:15, while services to Mae Nam are listed at 06:00, 07:00 and 13:15 depending on the sailing.
A combined ticket is particularly useful when arriving by overnight train because the transfer and ferry are coordinated as one journey.
Why this option works well
- No need to arrange separate transport between the railway station and pier
- Convenient for travelers arriving on an overnight train
- One booking can cover the land and sea portions
- Less complicated than organizing several individual tickets
- Suitable for travelers continuing directly to Koh Samui
The exact departure times and fares can change, particularly between seasons, so the published timetable should be checked shortly before travel.
Chumphon town to Koh Samui by bus and ferry
Travelers already staying in Chumphon do not need to return to the railway station.
A typical journey is:
Chumphon town → minivan/bus → ferry pier → catamaran → Koh Samui
Combined transfer tickets can be arranged from Chumphon, with the road portion connecting the town or accommodation area to the relevant pier.
Expect the complete journey to take approximately 5–6 hours, depending on the departure and ferry connection.
A combined ticket is generally more convenient than booking the road transfer and ferry separately, particularly if this is your first time traveling through Chumphon.
Taking the ferry directly from Chumphon
Independent travelers can also make their own way to the ferry pier and purchase a ferry-only ticket.
The main departure point for Lomprayah services is Thung Makham Noi/Lomprayah Pier, while Boonsiri operates from Paknam Chumphon Boonsiri Pier on its routes.
For Lomprayah, currently published schedules include services from Chumphon to Koh Samui with journey times of approximately 4 hours 15 minutes to 5 hours 30 minutes, depending on the departure and Samui pier.
This option can make sense if you:
- Are already near the pier
- Have arranged your own private transfer
- Want greater control over your travel arrangements
- Are combining Chumphon with another mainland destination
However, the apparent saving from buying a ferry-only ticket can disappear once the cost of reaching the pier is added.
Which Koh Samui pier will you arrive at?
The arrival pier is important because Koh Samui is a relatively large island and the journey to your accommodation can vary considerably.
Bangrak Pier
Bangrak is on the northeastern side of Koh Samui, close to the airport and the popular Chaweng and Bophut areas.
It is particularly convenient for:
- Bophut
- Fisherman’s Village
- Chaweng
- Koh Phangan connections
- Travelers staying in northeastern Koh Samui
Mae Nam / Pralarn Pier
Mae Nam is on the northern coast and is convenient for travelers staying around Mae Nam, Bophut and the northern part of the island.
Published 2026 schedules currently show Lomprayah services arriving at Mae Nam Pier, with some departures taking approximately 4 hours 15 minutes to 4 hours 30 minutes from Chumphon.
Before booking, check the exact arrival pier rather than simply searching for “Koh Samui.” The pier can make a significant difference to the final transfer time.
Chumphon to Koh Samui by train: what travelers need to know
There is no train from Chumphon to Koh Samui.
Thailand’s Southern Railway Line reaches Chumphon on the mainland. From there, travelers must transfer to road transport and then a ferry or catamaran to reach Koh Samui. The State Railway of Thailand’s timetable confirms Chumphon as a station on the Southern Line.
This is why travel websites sometimes describe the journey as a “train to Koh Samui.” In reality, it is a train + transfer + ferry journey.
For travelers coming from Bangkok, the overnight train can be particularly practical. Instead of paying for a hotel in Bangkok and traveling during the day, passengers can travel south overnight and continue toward the islands after arriving in Chumphon.
Bangkok to Koh Samui via Chumphon
The classic overland-and-sea itinerary is:
Bangkok → Chumphon by train → Chumphon pier → Koh Samui by catamaran
The overall journey from Bangkok generally takes around 12–16 hours, depending on the train and ferry connection.
The main advantage is cost. It can be substantially cheaper than flying directly to Koh Samui, although it is much longer.
The State Railway of Thailand currently provides an online timetable for the Southern Line, and schedules are subject to change.
For an overnight journey, a sleeper berth is generally more comfortable than an ordinary daytime seat, particularly when continuing directly to the islands the following morning.
Chumphon to Koh Samui vs Chumphon to Koh Tao
Chumphon is especially well positioned for Koh Tao.
The geography makes Chumphon a natural starting point for travelers visiting the Gulf islands from north to south:
Chumphon → Koh Tao → Koh Phangan → Koh Samui
Koh Tao is considerably closer to Chumphon than Koh Samui, so travelers planning an island-hopping itinerary may find it more efficient to visit Koh Tao first and continue south.
Boonsiri’s published timetable, for example, lists Chumphon–Koh Tao catamaran services with journey times of around two hours on its current schedule.
This makes Chumphon particularly attractive for travelers who want to combine several Gulf islands rather than visit Koh Samui alone.
Chumphon or Surat Thani for Koh Samui?
Both mainland gateways can be used to reach Koh Samui, but they serve slightly different itineraries.
Chumphon is particularly useful when:
- You are traveling from Bangkok by train
- You want to visit Koh Tao
- You are already in southern Chumphon Province
- You are planning a north-to-south Gulf island itinerary
Surat Thani is particularly useful when:
- You are arriving by air at Surat Thani Airport
- You are already traveling through Surat Thani
- Your itinerary includes mainland southern Thailand before Koh Samui
Chumphon should not automatically be considered the fastest route to Samui. The best gateway depends heavily on where you are coming from and whether Koh Tao is part of the itinerary.
2026 ferry schedules and prices
Schedules on this route are not fixed year-round. Weather, seasonal demand and operator timetable changes can affect both departure times and availability.
For late August and early September 2026, published Lomprayah timetable information shows:
| Route | Example departure | Example arrival | Approx. duration |
|---|---|---|---|
| Chumphon → Bangrak | 05:45 | 11:15 | 5h 30m |
| Chumphon → Mae Nam | 06:00 | 11:30 | 5h 30m |
| Chumphon → Mae Nam | 07:00 | 11:30 | 4h 30m |
| Chumphon → Mae Nam | 13:15 | 17:30 | 4h 15m |
These are examples from the currently published 2026 timetable, not a guarantee for every travel date.
Lomprayah also notes that its 2026 timetable covers routes across Koh Tao, Koh Phangan and Koh Samui and provides current booking information through its official website.
How much does Chumphon to Koh Samui cost?
As a general planning figure, travelers should budget approximately:
- Ferry only: around THB 960–1,200
- Train station + ferry: around THB 1,260–1,500
- Town/hotel transfer + ferry: around THB 1,200–1,500
- Hotel transfer on Koh Samui: potentially more depending on the destination
These are useful budgeting ranges rather than guaranteed fares. Transfer-inclusive tickets are normally more expensive because they include the road section on the mainland and, in some cases, onward transport on Samui.
Is a combined ticket worth it?
For most first-time visitors, yes.
A combined ticket reduces the number of separate connections that need to be arranged:
Train → transfer → pier → ferry → Samui
It is especially useful when arriving on an overnight train, because missing the ferry connection could otherwise mean waiting several hours for the next departure.
Independent travelers who are already staying near the pier may prefer a ferry-only ticket, but they should calculate the cost of getting to the pier before comparing prices.
Traveling during the monsoon season
Weather is an important consideration when crossing the Gulf of Thailand.
High-speed catamarans are more exposed to rough sea conditions than larger conventional ferries. During periods of poor weather, services can be delayed, rescheduled or cancelled.
For an itinerary involving several islands, avoid scheduling a flight immediately after a ferry journey when possible. Allowing some flexibility is particularly sensible during periods of unsettled weather.
Boonsiri’s current 2026 timetable also distinguishes between seasonal operating periods, illustrating why travelers should check the operator’s latest schedule rather than relying on an old timetable.
Luggage and ferry travel
Most high-speed ferry services have designated luggage areas, but space can be more limited than on a train or coach.
For a smoother journey:
- Keep valuables and essential medication in your hand luggage.
- Label larger bags clearly.
- Avoid carrying more luggage than necessary.
- Keep important travel documents accessible.
- Check the operator’s current baggage conditions before departure.
If you are traveling with large suitcases, confirm the baggage allowance when booking because conditions can differ between services.
How to choose the best route
The best option depends primarily on your starting point.
From Bangkok:
Take an overnight train to Chumphon, then continue by combined transfer and ferry.
Already in Chumphon:
A town-to-pier transfer combined with the ferry is usually the simplest choice.
Staying near the ferry pier:
A ferry-only ticket may be more convenient.
Visiting Koh Tao first:
Travel from Chumphon to Koh Tao, then continue south to Koh Phangan and Koh Samui.
Short on time:
Flying directly to Koh Samui is considerably faster, although usually more expensive.
Recommended itinerary: Bangkok → Chumphon → Koh Samui
For travelers who want to experience the journey rather than simply reach Samui as quickly as possible, a practical itinerary is:
Day 1:
Take an overnight train from Bangkok to Chumphon.
Day 2:
Transfer from Chumphon Railway Station to the ferry pier and take a high-speed catamaran to Koh Samui.
Days 2–5:
Explore Koh Samui.
Optional:
Add Koh Tao and Koh Phangan before continuing to Samui for a longer Gulf island itinerary.
This route combines the convenience of overnight rail travel with a relatively straightforward ferry connection.
