Sunset cruise Koh Samui: shared dinner cruises from about 2,400 THB, private longtails from about 2,500 THB a boat, plus speedboats, routes and piers.
Overview
A sunset cruise in Koh Samui is either a shared seat on a scheduled boat (the Red Baron dinner cruise lists at about 2,400 THB, roughly 68 USD, per adult in 2026) or a private charter, from about 2,500 THB (~71 USD) for a short longtail sunset to tens of thousands of baht for a speedboat or yacht. Boats range from open longtails to a traditional junk, speedboats and catamarans, running short sunset loops off the south and west coast, half-day trips to Koh Tan, or full-day charters to Ang Thong Marine Park. This guide compares the booking styles, boat types and 2026 prices, and covers which pier you leave from and when the Gulf is too rough. Prices are operator-listing ranges and vary widely: confirm with the operator.
Key takeaways
- Shared: the Red Baron, a traditional sailing junk from Bophut, lists at about 2,395 THB (~68 USD) per adult (1,595 THB for ages 5-10) with transfers, drinks and a buffet. One listing says it sails on Fridays and Sundays, 16:00-19:00, not nightly: check the day.
- Private: a longtail sunset to the Five Islands is listed from about 2,500 THB (2 hours) and a longer private longtail to Koh Tan from about 3,200-7,560 THB, depending on operator and group size. Private speedboats start around 14,000 THB for a half day.
- Five Islands and Koh Tan are the classic short sunset routes; Ang Thong Marine Park is closed from about 1 November to mid-December.
- Crew and life jackets are standard; food, drinks and park fees vary by operator.
- October-December swell can cancel or reroute cruises from exposed west and south piers: check conditions on the day.
Shared Sunset Cruises vs Private Charters
A shared sunset cruise puts you on a scheduled departure alongside other travelers, at a fixed per-person price with no control over the group size or exact route. Boats like the Red Baron run this model on set evenings (one listing says Fridays and Sundays), selling individual seats for a set itinerary, cheaper per head, but you share the deck, the sunset photo spots and the dinner buffet with many other guests.
A private charter reserves the entire boat (longtail, speedboat, catamaran or small yacht) for your own group, with the captain adjusting the route, stops and timing to your plan. It costs more overall but splits down to competitive per-person pricing once a group hits four to six people, and it’s the only way to build a custom multi-island day or a private run to Ang Thong Marine Park. Couples on a Koh Samui honeymoon and groups wanting a fixed departure time or a specific beach stop both lean toward private hire over a shared seat. If you want a sailing yacht rather than a motor boat, or want to work aboard as crew, see sailing on Koh Samui.
Boat Types: Longtail, Speedboat, Catamaran and Traditional Junk
Four boat types cover almost every charter and cruise booking on Koh Samui, each suited to a different route, budget and group size.
Longtail boats are open wooden fishing boats with a long propeller shaft, typically seating 6-10 people. They’re the cheapest private charter option, best for short hops to nearby islands like Koh Tan or a Five Islands sunset loop from Thong Krut or Taling Ngam, but offer little shade or comfort on longer crossings.
Speedboats carry 8-15 passengers, cover ground fast (Ang Thong in roughly 45-60 minutes each way versus 1.5 hours by big boat), and dominate both shared day-trip tours and private full-day charters: see the full day trips guide and island hopping guide for routes beyond a sunset loop.
Catamarans trade speed for stability and deck space, running from mid-size 18-passenger boats up to 70-foot vessels carrying 60 guests for group sunset cruises. Their twin-hull design handles Gulf chop better than a monohull, making them the common choice for larger shared bookings and multi-day sailing charters.
Traditional junks, rigged with red sails in the classic Southeast Asian style, are the largest and most photogenic option: the Red Baron, based in Bophut, is a 30-meter junk carrying up to 70 passengers on its nightly sunset dinner cruise, and is also offered for private charter.
Popular Routes: Five Islands, Koh Tan Sunset and Ang Thong Overnight
Three routes account for most sunset cruises and charters booked from Koh Samui, each suited to a different amount of time on the water.
The Five Islands route threads a longtail or small cruiser between limestone outcrops off the southwest coast, timed to finish with the sun setting behind the Ang Thong archipelago, a roughly 4-hour round trip from Thong Krut or Taling Ngam. The Koh Tan sunset run covers similar ground closer to shore, often combined with a snorkel stop before the return leg; see the snorkeling guide for what’s in the water along the way. Both suit a half-day booking and don’t require an early start.
An Ang Thong charter is the route that most justifies a private boat over a day tour: a private speedboat sets its own timing, so you can reach the islands before the day-tour crowds and start the Ko Wua Talab viewpoint climb early. Overnight arrangements vary by operator, and the park is closed about 1 November to mid-December. There’s no scheduled public transport to Ang Thong National Marine Park: every visit runs on a booked group tour or a private charter departing Nathon or Bang Rak, as covered in the Ang Thong Marine Park guide.
How Much Does a Sunset Cruise Cost in Koh Samui? (2026)
Prices below come from operator and booking-site listings read in October 2026. They differ widely by operator, season, group size and boat, so treat them as ranges.
A shared Red Baron sunset dinner cruise lists at about 2,395 THB (~68 USD) per adult and 1,595 THB (~45 USD) for ages 5-10; listings range from about 2,350 to 2,550 THB. Resort-run cruises, such as Four Seasons’ 2-hour 5 pm sunset cruise, are priced separately. Semi-private small-group sunset cruises on booking sites list from roughly 79-100 USD per person.
A private longtail is the cheapest private option: about 2,500 THB (~71 USD) for a roughly 2-hour Five Islands sunset charter, and about 3,200-7,560 THB (~91-215 USD) for a longer Koh Tan or Koh Madsum tour (up to 5 guests about 5,640 THB, 6-10 guests about 7,560 THB on one operator). Some listings run much higher for the same area, so compare two or three.
A private speedboat is a bigger spend: half-day rates start around 14,000 THB (~400 USD), while full-day boats for 12-20 guests list around 27,000-45,000 THB (~770-1,290 USD) with transfers, snorkel gear and refreshments, and larger custom speedboats reach 42,000-82,000 THB. A private Ang Thong day by speedboat starts around 32,850 THB (~940 USD) for up to 10 guests. Park fees (300 THB adult as of 2026) and lunch can be extra.
Yachts and catamarans list from roughly 18,800-21,200 THB (~540-600 USD) per day for smaller boats, scaling with size. Alcohol, a full dinner menu and water toys are usually quoted separately.
Where to Watch the Sunset and What a Cruise Includes
The west coast has the island’s best sunset horizons: see the sunset guide for land-based spots, and the rooftop bars guide for drinks with a view. On a cruise, the boat heads out in late afternoon, stops for a swim or snorkel on some routes, and times the return to the sunset. The Red Baron dinner cruise lists return hotel transfers, a welcome drink, soft drinks, water and tea, a buffet dinner and fruit. Wear light clothing and bring a layer for the breeze, and reef-safe sun cream for a snorkel stop.
How to Book and Which Pier You Leave From
Book a shared sunset cruise or day-tour speedboat through your hotel tour desk, a pier-side agent, or directly with the operator’s website or WhatsApp line, most confirm within a day and collect payment on boarding. Book a private charter (longtail, speedboat, catamaran or yacht) at least a few days ahead in high season (December-February), longer for an Ang Thong day or a larger catamaran, since boats and crew get booked out around the busiest weeks.
Departure pier depends on the route: Five Islands and Koh Tan sunset trips leave from Thong Krut or Taling Ngam on the south coast; the Red Baron and most catamaran or yacht charters leave from Bophut on the north coast; Ang Thong charters leave from Nathon or Bang Rak, and listings also name Bophut as a speedboat departure. See the full ferry piers guide for directions, parking and facilities at each one.
Seasonal Sea Conditions and Caveats
Sea state, not the calendar, decides whether a sunset cruise runs as booked. Koh Samui’s north coast around Bophut stays calm nearly year-round, which is why most catamaran and yacht charters base there, while the south and west coast piers used for Five Islands and Ang Thong routes pick up afternoon chop from May to September and swell from October to December: see the full sea conditions by month guide for a coast-by-coast breakdown.
Ang Thong Marine Park itself closes for about six weeks, from roughly 1 November to mid-December each year, so no Ang Thong charter runs then. December through April brings the calmest, most reliable window for both shared cruises and private charters. Outside that window, operators may shorten a route, swap a longtail for a more stable speedboat, or cancel outright in strong wind: confirm the day before rather than assuming your booking is guaranteed, and build a spare evening into your itinerary if a specific sunset cruise matters to your trip.

FAQ
How much does a sunset cruise cost in Koh Samui?
A shared sunset dinner cruise on the Red Baron lists at about 2,395 THB (~68 USD) per adult in 2026, including transfers, drinks and a buffet. A private longtail sunset to the Five Islands is listed from about 2,500 THB (~71 USD) for the whole boat, and private speedboats start around 14,000 THB for a half day. Operator prices vary, so compare a few.
Where is the best place to watch the sunset on Koh Samui?
The west coast faces the Gulf, so Lipa Noi, Taling Ngam and Nathon have the clearest sunset horizons; the east coast does not. See the sunset guide. From the water, the Five Islands route is timed to finish at sunset.
What happens on a sunset cruise?
The boat leaves in the late afternoon, may stop for a swim or snorkel, and returns after sunset. On the Red Baron you get a welcome drink, soft drinks and a buffet dinner on deck, with hotel transfers.
What’s the difference between a shared and a private boat charter?
A shared cruise sells individual seats on a fixed departure and route, at a lower per-person price but no control over timing or stops. A private charter reserves the entire boat for your group, letting you set the route and schedule, and becomes cost-competitive per person once four or more people split the boat fee.
Which pier do Koh Samui boat charters leave from?
It depends on the route: Five Islands and Koh Tan sunset trips leave from Thong Krut or Taling Ngam on the south coast, the Red Baron and most catamaran charters leave from Bophut, and Ang Thong charters leave from Nathon or Bang Rak. See the ferry piers guide for directions to each.
Can I charter a boat to Ang Thong Marine Park overnight?
Private charters to Ang Thong Marine Park run mainly as full-day speedboat trips, from about 32,850 THB (~940 USD) for up to 10 guests; overnight arrangements vary by operator, so ask what is allowed. The park is closed about 1 November to mid-December. There is no scheduled public ferry: every visit runs on a booked tour or private charter.
What boat is best for a Koh Samui sunset cruise?
A traditional sailing junk like the Red Baron (which one listing says sails on Fridays and Sundays) gives the most atmosphere for a shared sunset dinner cruise, while a private longtail or speedboat suits a smaller group wanting a specific route like Five Islands or Koh Tan. Larger groups or those wanting more stability on choppy days should book a catamaran.
Is it rough to book a boat charter outside the dry season?
It can be. October through December brings the most Gulf swell, especially on routes leaving from south and west coast piers, and operators may shorten routes or cancel in strong wind. December through April is the calmest, most reliable window for both shared cruises and private charters: see the sea conditions by month guide for a full breakdown.
