The experience

The day starts with hotel pickup between 8:30 and 9am, then a 15-minute speedboat ride to Koh Tan. You spend an hour snorkeling over tropical coral and colorful fish in shallow water: the reef sits close to shore and the island lies only a few hundred meters from Koh Samui's southwestern coast, so the crossing is short. Life jacket and snorkeling mask are provided.

After snorkeling, the boat heads to Koh Madsum, a smaller island next door that stays quieter than the bigger marine parks because only a few operators run trips there. You get a kayak and paddle around the island's edge, or swim and sunbathe on the white sand beach while lunch is being prepared. A small restaurant on the island serves a buffet, and soft drinks and fresh fruit come with it. Sunbed and towel are yours for the afternoon.

The return journey leaves Koh Madsum at 2:30pm, getting you back to your hotel by 2:45pm. Accident insurance is included in the price. The activity suits all fitness levels, though it is not recommended for travelers with spinal injuries, poor cardiovascular health, or pregnancy. Children from age 4 are welcome on a child ticket.

Is this one for you?You do the snorkeling and kayaking yourself with a guide leading the group: a shared activity, not a tour where you watch from a boat. Book this if you want to be in the water and moving under your own power, and if a morning departure that gets you back by mid-afternoon fits your schedule.
