Lunch was also lovely. Highly recommend if you want to see Koh Mad sum. We did the trip with our five year old who also enjoyed it.”

2.Pig Island Snorkeling and Koh Tan Speedboat Tour

★★★★★★★★★★4.2 · 1,673 reviews · 4h 30m · from $51

Speedboat snorkeling at Koh Tan and Pig Island at Koh Mudsum, with kayaking, Thai lunch, and hotel pickup.

“Apart from being picked up a little earlier than really necessary (shoved in a bar for 45 minutes before the boat was ready) it was a really great day. The minibus found us fine, the journey down was good, and our guide (young guy) was really great throughout - shout out to him! Waters were a bit murky for snorkelling but we saw a bunch of fish inches away from us and then the pigs were amazing. 7 or 8 little piglets and a bunch of fatties. Food was great too and the drinks on the island aren’t a rip off. A great day :)”

Snorkelling was fab we saw so many vibrant fish and corals. No turtles unfortunately but that can never be guaranteed! Lunch was tasty and the guide was friendly and knowledgeable.”

4.Ang Thong: Marine Park Full-Day Kayaking & Snorkeling Tour

★★★★★★★★★★4.6 · 768 reviews · from $68

Full-day Ang Thong Marine Park kayaking and snorkeling from Koh Samui, with caves, Emerald Lake views, and a Thai buffet lunch.

“Boat: The boat was comfortable and we had enough space. It was big enough and the sea was calm for us so it was a smooth ride. Staff: The guides and assistants were all nice and helpful. There were about 50 guests and it felt like an adequate number of staff. Activities: The conditions weren’t ideal for snorkeling but that’s of course not the company’s fault. The kayaking, however, was lovely. There was an opportunity to kayak a second time as well. A highlight for me was climbing to the viewpoint on Wua Ta Lap Island. This is no joke of a hike as it’s 500 meters up steep uneven…”

★★★★★★★★★★4.3 · 658 reviews · 7h 30m · from $73

Koh Samui Angthong Marine Park speedboat day: snorkel at Wao Island, kayak and hike, Thai buffet lunch, and Mae Koh Emerald Lagoon views.

“When i was choosing the company to go with for the tour i have read reviews. And they totally differs. I went with this one cause well it was cheaper than other speedboat tours. And everything was just fine as it should be. Prompt on time pickuo from hotel, then after check-ins waiting in the area for all the passengers, who were split into 4 groups, meaning 4 different speedboats. While waiting you can get some light breakfast like toast and jam, tea/coffee. Then we left just after 9 am, the drive was good, we took meds from sea sickness 1h before departure, so no bad feelings about bumps in…”

7.Jetski Safari, Snorkeling to Pig & Virgin Islands

★★★★★★★★★★4.6 · 364 reviews · 2h 30m · from $220

Jet ski safari from Koh Samui with snorkeling at Koh Tan and a visit to Pig Island (Koh Mat Sum), plus hotel pickup.

“Felt it was very expensive for what you got but the jet ski’s were fun and very powerful. It did include snorkelling but the visibility was very poor so it was a bit pointless. The guides had very limited English which is fine but they would take us to places and we had no idea why we were there or what we were meant to do. Pig island was very cute but I must pass on warning that they aren’t all friendly!! My boyfriend got bit and ended up having to go to hospital to start rabies injections and antibiotics…again not the fault of the tour but it would have…”
