Boat Tours

Speedboats: Best for covering more distance in one day (often Ang Thong and sometimes Koh Tao). Expect a faster, noisier, bumpier ride. Not ideal for anyone with back or neck issues, those who are pregnant, or travelers who get seasick easily.

Longtails: Best for shorter distances and a slower pace, especially for Koh Tan and Koh Madsum. They work well for small groups and families, and private longtails can be more flexible with timing and stops.

Sailing catamarans and larger yachts (including junk-style): Best if comfort matters more than packing in lots of stops. These are usually calmer, with more shade and space, and are popular for sunset cruises and relaxed day sailing.

Most tours start with hotel pickup (or a meet-up point), followed by a short transfer to a pier. Check-in is usually straightforward: name list, briefing, and life jackets. After that, you’ll head out for scheduled stops and return in the late afternoon or evening depending on the route.

Full-day trips: Typically 7–9 hours door-to-door. Expect a morning departure, a few swim or snorkel stops, and lunch (either on a beach, at a simple restaurant, or served onboard).

Half-day trips: Typically 4–6 hours door-to-door. These usually stay close to Samui (often Koh Tan and Koh Madsum) and can feel less rushed.

Sunset cruises: Usually 2–4 hours. They focus on a smooth sail, a swim stop if conditions allow, and sunset timing. Dinner or snacks depend on the operator and package.

Routes and stop order can change based on sea conditions, tide, and crowd management. On windier days, operators may shorten the program or choose more sheltered bays.

Most tours provide life jackets and basic snorkeling gear (mask and snorkel; fins are sometimes available but not guaranteed). Drinking water is commonly included, and lunch is typical on full-day trips.

Bring swimwear, a towel, sun protection, and a light cover-up for the ride back (boat decks can get breezy). A small dry bag helps keep phones and valuables protected, and water shoes are useful for beach landings, slippery steps, or rocky shore entries.

If you’re prone to motion sickness, take medication before pickup and avoid heavy breakfasts. Sitting toward the middle of the boat generally feels steadier than the bow.

Sea conditions in the Gulf can change quickly. Safety-related route changes and cancellations happen occasionally, especially on longer, more open-water routes. Build a bit of flexibility into your schedule and avoid booking anything time-critical immediately after a full-day boat trip.

Speedboat rides can be physically demanding in choppy seas. If you have back, neck, or joint issues, choose a larger boat or sailing option, and let the operator know in advance.

National park fees may be collected separately on certain routes (commonly cash). What’s included varies by operator, so check your booking details carefully.

Snorkeling visibility is weather-dependent. After strong winds or heavy rain, water clarity can drop, and the best days tend to be when the sea is calm.

Choose the right boat for your priority: If you want to see more places in one day, pick a speedboat. If you want a calmer ride and more comfort, choose sailing or a larger yacht-style boat. If you want flexibility close to Samui, a private longtail is often the simplest option.

Factor in transfer time: Koh Samui is spread out. A tour departing from a pier on the opposite side of the island can add meaningful pickup time. If you’re staying in Chaweng, Lamai, or the south, confirm the pier location and pickup window.

Pack for the boat, not the beach: Sun is stronger on the water, and shade can be limited. A long-sleeve rash guard and a hat you can secure (or store) are more practical than you’d expect.

Cash helps: Small purchases, tips, and occasional fees are easier with cash, especially if you’re stopping at small islands or local piers.

Keep expectations realistic at popular stops: Ang Thong and the most famous viewpoints can get busy in peak season. Early departures and smaller-group tours tend to feel less crowded than the biggest boats.

Be considerate around animals and beaches: Don’t feed animals unless the staff specifically instructs it, and avoid leaving food unattended. Take your trash back to the boat whenever possible.
