An Overview of the Experience

This five-hour trip takes you from Koh Samui to two charming islands: Koh Madsum and Koh Tan. Departing from Thong Krut Pier, you’ll hop onto your private long tail boat — a classic Thai vessel that offers an authentic, albeit bumpy, ride through the Gulf. The journey itself is part of the adventure, with picturesque views and the opportunity to take photos of the coastlines and distant islands.

The experience kicks off with a 15-minute sail to Koh Madsum, a small island famed for its white sandy beaches and tranquil vibe. Once ashore, you’re free to swim, relax, or perhaps grab a kayak (if available). One reviewer mentioned how they enjoyed the “blue waters and golden sand” — perfect for those who want a peaceful, picture-worthy escape.

After some downtime, your boat takes you to Koh Tan, a slightly larger island with excellent coral reefs and clear waters for snorkeling. The marine life is generally vibrant, with reports of seeing fish, rays, and even some small sharks. Snorkel gear is usually provided or available to rent, and the shallow waters make it accessible for all levels.

The return trip to Koh Samui wraps up the tour, and you’ll be transported back to your hotel — a straightforward way to wind down after a fun-filled half day.

What to Expect: From Pickup to Drop-off

Pickup and Transportation: The tour includes hotel pickup from your Koh Samui accommodation in Bo Put, Maenam, or Maret. Expect a prompt collection, usually in the morning, depending on your chosen start time. The transportation to Thong Krut Pier is private, which makes the start hassle-free.

Boat Journey: The private long tail boat ride is a highlight — it’s not just transportation but also a chance to enjoy the views of the coastline and surrounding islands. The boat is cozy and typically well-maintained, but be prepared for some splash and wind, especially if it’s a windy day.

Island Time at Koh Madsum: Once on Koh Madsum, you’ll have about an hour or so to relax. The beach is wide and inviting, perfect for swimming or simply soaking up the sun. As one reviewer pointed out, there’s also the option to kayak or explore the small island on foot.

Koh Tan Snorkeling: The second stop is Koh Tan, known for its crystal waters and lively marine ecosystem. Snorkeling here is generally appreciated, with reviews noting the chance to see small tropical fish, rays, and even two sharks. You’ll likely spend around an hour here, so bring your snorkel gear and get ready to see marine life up close.

Return and Drop-off: After snorkeling, the boat heads back to Koh Samui, where your guide will transfer you back to your hotel. The entire experience lasts about five hours, including transfer times and island stops.

The Real Value Behind the Tour

While the price tag may seem high for a half-day, consider what’s included: private transportation, guidance in English, and visits to two distinct islands. The personalized nature of a private group is a major plus, especially if you prefer not to share space with large crowds.

The guides seem to be well-reviewed for their attentiveness and knowledge, with one reviewer mentioning how a guide quickly helped them deal with a small cut, and another praising the guide for taking excellent photos. It’s those small touches — caring for guests and capturing memories — that elevate the experience.

Timing and pace are worth noting. Some reviews point out that the tour can feel a bit rushed, especially if you want more time on each island. It’s good to be prepared for a swift schedule, but overall, the focus remains on enjoying the scenery and marine life.

Snorkeling gear is often included, so you won’t need to rent or bring your own unless you prefer specific equipment. Be sure to pack essentials like sunscreen, a towel, sunglasses, and cash — some reviewers noted the importance of waterproof bags and dry clothes after getting wet.

Another interesting point: For those concerned about waterproofing or staying dry, it’s wise to bring waterproof bags, especially since the boat ride can be splashy and some travelers arrived empapados (soaked).

This experience is best suited for families, couples, or small groups who want a manageable, well-organized day of island hopping. If you’re after relaxing beaches and snorkeling without the crowds, it delivers in spades.
