Private Koh Samui Secret Islands Boat Trip
Koh Mudsum's beach, snorkelling at Koh Tan and a beachside lunch, with private minibus transfers

What makes this different
The listing describes the islands south of Koh Samui as far from mass tourism, and this trip goes to two of them from the fishing village of Thong Krut. Koh Samui Advisor runs it as a private tour, with transfers in an air-conditioned minibus that picks up only your party on the way out, a start time you can set and a boat crossing of about 30 minutes. The price is quoted per group of up to two people.
The first stop is Koh Mudsum, a small island with white sand beaches and no electricity or running water, a small bar and pigs that live on the beach. The boat then continues to Koh Tan for snorkelling in calm, clear water, with equipment provided at no charge. A traditional lunch is prepared at a small restaurant on the beach, and the listing says it will not be too spicy. After lunch there is time to walk on paved paths through a mangrove forest on Koh Tan, where signs describe the plants and animals, or to rest on the beach. The minibus then takes you back to your hotel. The trip lasts about six hours.
The price includes accident insurance, the mobile ticket, a tour guide, pickup and return, lunch and soft drinks, snorkelling gear and the entrance fee for Koh Mudsum. Personal expenses are extra. Bring a sun hat, swimwear, a change of clothes, sunscreen and rain gear. The tour is not suitable for pregnant women, cruise ship guests or babies under one year. To reserve for the following day, book by 9:00 PM the day before.
The listing also says the tour runs with a small group, so check with the operator whether other guests may join the boat. It is booked through GetYourGuide with free cancellation up to 24 hours before the start. It suits couples and small families who want a boat day with few other people and without the long transfers of the larger islands.
