About this tour
When Em from our BugBitten team booked the Red Baron, we weren't expecting to find one of Koh Samui's largest sailing junks — but there it was, all red sails and proper deck space. You pick your flavour: Sunset Cruise around Koh Som, Angthong Marine Park with its crater lake viewpoint, or Koh Phangan's secret beaches. The boat handles groups well, with breakfast or lunch buffets depending on which you choose, snorkelling gear sorted, and an English-speaking host steering things. It's eight hours of actual sailing, not a speedboat dash, so you feel the pace of the Gulf.
Highlights
- Red sails and proper junk-style hull — feels authentic, not a party-boat gimmick
- Angthong's Koh Mae viewpoint overlooks Emerald Lake in an extinct volcano crater
- Decent deck space means you're not shoulder-to-shoulder with fifty strangers
- Lunch or breakfast buffet included; fresh fruit, snacks, tea, coffee all day
- Snorkelling gear provided — swim in genuinely clear water at multiple stops
- Hotel transfers included from your base around Koh Samui
- Sunset Cruise option ends with dinner on board as day winds down
What to expect
The Red Baron picks you up from your hotel and heads out into the Gulf. On the Angthong run — the one Em tried — you get a full breakfast on board, then sail toward the marine park. The boat anchors near Koh Mae and you hike up to the viewpoint; the crater lake really does glow emerald, and it's worth the short climb. You'll stop to snorkel (the water's clean and warm), then anchor again for a buffet lunch on deck. The whole rhythm feels unhurried — this is sailing, not speedboat tourism. The sunset cruises hit Koh Som, which feels quieter than the main beaches; if you swim, the water's shallow and calm. Crews are matter-of-fact, which works: they're not doing theatre, just running a boat.
Weather matters. If wind drops, you motor. The boat can feel a bit crowded if you hit a full passenger load (minimum 10, no stated maximum), but the deck is genuinely spacious compared to the tourist dinghies dotted around the bay. Expect to be with a mix of couples, small groups, and families — mostly relaxed, mostly just there to float and eat.
What travellers say

Good to know
If you want actual sailing — canvas, wind, the lot — rather than a screaming speedboat, this lands it. The Angthong Emerald Lake stop is a genuine highlight and not something you'll do casually from a beach day. Food's proper buffet standard, not skimpy. Snorkelling's included with gear, so no rental fee. Hotel transfers take the logistical friction out. Runs year-round. Kids aged 7–12 pay child rates; under 6 go free.
Minimum 10 passengers required, so occasionally tours get cancelled in low season — check well ahead. Not suitable if you're arriving via cruise ship or have mobility issues boarding a sailing vessel. Pregnant guests or those with heart conditions, high blood pressure, or bone disease should skip it. Swimming stops aren't guaranteed swims (some folk just watch from deck), so bring swimmers anyway. Early morning departure (exact time depends on your option), so not a lie-in affair. Angthong cruises are long days — eight hours door-to-door. Tell them about dietary needs at least two days prior.
Swimwear, sunscreen, a light layer for wind, hat. Snorkelling gear's supplied but bring your own if you prefer. The boat's stable but not sheltered, so prepare for sun and spray.
