A Clear, detailed look at the Koh Tao Premium Snorkel Tour onboard the Oxygen
Imagine cruising around Koh Tao with a small, friendly group of up to 25 people, exploring some of the most breathtaking snorkeling spots in the Gulf of Thailand. For about $37 per person, this 6-hour morning adventure takes you to Freedom Bay, Buddha Rock, Shark Bay, Ao Luek, and Tao Thong Bay, packed with vibrant coral reefs, sea turtles, and even the occasional baby shark. Starting at 9:00 am with hotel pickup (though not from Mango Bay or Lighthouse Beach), you’ll spend the day with a professional crew, enjoying the perfect mix of guided exploration and relaxed free time.
What we love about this tour is the limited group size, which keeps the experience intimate and less stressful for both guests and marine life — no giant crowds here. The onboard meals are another highlight: sandwiches, panna cotta, and fresh fruits provide a delightful recharge between snorkeling sessions. Plus, the inclusion of snorkeling equipment, life jackets, and basic insurance makes for a worry-free trip.
One potential consideration is that hotel pickup isn’t offered from Mango Bay and Lighthouse Beach, so if you’re staying there, you’ll need to arrange transportation separately. Also, while the tour offers a great balance of activity and relaxation, some guests mention that the pace can feel a little rushed, especially at the more popular stops like Nang Yuan Island. Still, if you’re craving authentic marine encounters and a well-organized day at sea, this tour fits the bill perfectly.
This experience is best suited for those who want to see multiple snorkeling spots in one day without the crowds, appreciate good food and professional guidance, and enjoy smaller groups for a more personal adventure. Families, couples, or solo travelers eager for marine wildlife sightings will find plenty to love here.

How the Day Unfolds
This tour kicks off early, with hotel pickup (except from Mango Bay and Lighthouse Beach), setting a relaxed tone. Once you arrive at Mae Haad Pier, the crew checks you in, introducing the small-group vibe that many reviews praise — “nice boat, great crew, and lovely lunch,” as one guest shared. The boat departs around 9:30 am, heading toward Nangyuan Island, offering a scenic 30-minute cruise across the Gulf of Thailand.
Nang Yuan Island: The Highlight Viewpoint and Reef
Your first stop is Nang Yuan Island, renowned for its postcard-perfect photo ops and tranquil waters. Climbing the viewpoint gives panoramic views of the iconic sandbar connecting three tiny islands, giving you a moment to appreciate how special this place is. You get about an hour here, enough time to relax, take photos, and snorkel at the Japanese Reef Garden, known for its vibrant coral and marine biodiversity. One guest raved, “Nangyuan Island was amazing, and I didn’t feel rushed at all,” reinforcing its popularity.
Koh Tao: Snorkel at Tao Thong Bay and Enjoy a Tasty Lunch
Next, the boat heads back toward Koh Tao for a snorkeling session at Tao Thong Bay. Here, you can spot stock horn corals, and the water’s depth and clarity are ideal for low tide snorkeling. Meanwhile, the crew serves vegan or chicken sandwiches, along with panna cotta and fresh fruit — a thoughtful touch that keeps everyone energized. As one reviewer remarked, “The food was delicious and well-presented,” highlighting the tour’s attention to comfort and quality.
Mangrove Bay and Hin Wong Bay: Colourful Reef Encounters
The afternoon includes visits to Mango Bay and Hin Wong Bay, both offering excellent opportunities to see schools of colorful fish and other marine creatures. Each stop lasts about 30 minutes, providing enough time to snorkel and soak in the underwater scenery without feeling rushed. Reviewers consistently praise the guides for their helpfulness and the quality of the snorkeling gear, making sure everyone is comfortable and safe.
Shark Bay: The Quiet End with a Touch of Adventure
The final stop is Shark Bay, a private cove named for the blacktip reef sharks that frequent the area. It’s a peaceful spot shaded by coconut trees, perfect for unwinding or spotting the elusive sharks from a distance. The “spirit rocks,” Buddha Rock and Hin Yaai Mae, pass by en route, adding a mystical local touch to the journey. Guests have noted that the small group size makes this quiet retreat a highlight, especially for those interested in spotting sharks safely.
Practical Details and Comfort
Throughout the day, drinking water, coffee, tea, and fresh fruits are available on board, which many reviews find a considerate touch. The boat is equipped with toilets, and the crew is professional and friendly. The tour ends back at Mae Haad Pier around midday, free to continue your exploration or catch a ferry to your next destination, be it Koh Samui, Chumphon, or beyond.

Positive feedback highlights the knowledgeable guides, with many mentioning guides like Ton, who provided excellent explanations and kept the trip organized. “Great service from start to finish,” a reviewer noted, emphasizing the professionalism of the crew.
Marine encounters are a major highlight — “Saw turtles, sea anemone, coral, giant clams, and so many fish,” one guest reported. Others appreciated the delicious onboard meals and the “well-kept boat,” which make the day comfortable and relaxing.
