Snorkeling Koh Tao & Koh Nang Yuan from Koh Samui: Speed Boat

Snorkel two islands and two reefs in one morning, then spend the afternoon on white sand.

A full-day snorkeling trip from Koh Samui by speed boat to Koh Tao and Koh Nang Yuan, with hotel pickup, lunch and all equipment provided. You snorkel at Mango Bay's coral reef in the morning, eat on the beach, then spend the afternoon at Koh Nang Yuan — three connected islands where you can snorkel again, relax on sand or trek to the viewpoint. A live guide in English, Thai or Chinese leads the group; the speed boat keeps travel time short.

The Experience

The day starts with pickup from your hotel and a briefing at the pier before boarding the speed boat. The crossing to Koh Tao takes you to Mango Bay, where the first snorkel happens on a coral reef thick with colorful fish — the visibility here is what makes this stretch of the Gulf famous. Snorkeling equipment is provided and fitted for you; the reef is the main event of the morning, and you spend as much time in the water as the group's pace allows.

After snorkeling, the boat heads to a beachside restaurant for a buffet lunch and soft drink while you look out at the water. The afternoon moves to Koh Nang Yuan, a cluster of three small islands connected by sand and ringed with clear water. You can snorkel again from the beach if you want more time underwater, or walk the sand, swim in the shallows, or trek up to the viewpoint that overlooks all three islands. The choice is yours; most people split the afternoon between the water and the rest.

The speed boat saves hours compared to a slower ferry, which is why the itinerary fits two islands and two reef sites into eight hours. You're in a shared group with a live guide who speaks English, Thai or Chinese. The round-trip transfer means no arranging a ride to the pier or back to your hotel — the boat picks you up and drops you off. Full tour insurance is included in the price.

Top questions

What's the snorkeling like at Mango Bay on Koh Tao?

Mango Bay is a coral reef site known for high underwater visibility in the Gulf of Thailand and abundant colorful fish. It's the main snorkeling stop in the morning, and the reef is what draws most travelers to this trip.

Can I snorkel at Koh Nang Yuan in the afternoon, or is it just for relaxing?

Koh Nang Yuan has clear water and colorful fish, so you can snorkel again from the beach in the afternoon if you want. You can also swim, relax on the white sand, or trek to the viewpoint — the afternoon is flexible depending on what you choose.

How long is the speed boat ride from Koh Samui to Koh Tao?

The speed boat is faster than a regular ferry, which is how the trip fits two islands and two snorkel sites into eight hours. The exact crossing time depends on sea conditions, but the speed boat keeps travel time short so you spend more time in the water and on the islands.

Is snorkeling equipment included, or do I need to bring my own?

Snorkeling equipment is provided for both reef sites and fitted for you at the pier. You don't need to bring your own or rent separately.

What's included in the lunch?

Lunch is a buffet served at a beachside restaurant on Koh Tao, with a soft drink included. It's eaten on the beach with a view of the water.

Does the tour pick me up from my hotel?

Yes, round-trip hotel pickup and drop-off are included. The boat departs from the pier after a brief check-in, and you're returned to your hotel at the end of the day.
