Snorkel Tour to Koh Nangyuan and the hidden bays of Koh Tao onboard the Oxygen

A Practical Guide to the Snorkel Tour of Koh Nangyuan and Koh Tao’s Hidden Bays

If you’re heading to Koh Tao and want to skip the crowds while soaking up some of the island’s best sights, this snorkel tour onboard the Oxygen could be just what you’re looking for. The tour costs around $25.22 per person for a roughly 7-hour adventure that takes you to Koh Nangyuan, the coral reefs of Koh Tao, and several secret bays that are nearly impossible to reach on land. What’s more, it includes hotel pickup and drop-off, so you don’t have to worry about logistics—just show up ready for a day of aquatic discovery.

What we particularly like about this trip is how it balances popular sights with lesser-known gems. The viewpoint atop Nangyuan Island offers a postcard-worthy panorama, while the snorkel stops give you a chance to encounter exotic marine life like turtles, colorful fish, and vibrant corals. Plus, the friendly guides and included Thai-style lunch add a nice touch of local flavor.

What to Expect on this 7-Hour Snorkel Tour

The Itinerary in Detail

The day begins with hotel pickup on Koh Tao—most travelers will find this convenient, especially since the tour includes transportation to Mae Haad Pier, where you’ll meet your crew. Once there, you’ll check in, receive a brief safety overview and some tips from your guides, then board the Oxygen, a boat that comfortably holds up to 120 travelers—though, as some reviews mention, it can feel a bit crowded during peak season.

The first stop is Nangyuan Island, just a short cruise away. Here, you’ll have the opportunity to climb the 15-minute trail to the island’s famous viewpoint. From this vantage point, you’ll see the three islands forming a perfect circle, framed by turquoise waters—an iconic shot you’ll want to remember. After soaking in the views, you’re free to swim and relax around the island’s beaches, which are ideal for taking photos or just floating in the calm water.

Next, the boat cruises to Japanese Reef Garden near Koh Tao, widely praised as one of Thailand’s top snorkeling spots. Its soft and hard corals, teeming with parrotfish and angelfish, make for a vibrant underwater experience. According to reviews, this is by far the best snorkeling some travelers have done in Asia, with sightings of sea turtles and colorful marine life.

Midday, you’ll enjoy a Thai lunch box while cruising to the next set of snorkeling locations. The meal is simple but tasty, and included in your package, making it a good value considering the full day of activities.

In the afternoon, the tour makes stops at Mango Bay and Lighthouse Bay, where snorkeling continues among coral reefs and shoals of fish. Another highlight is Hin Wong Bay, known for its colorful marine life, and Ao Leuk, with its crystal-clear waters perfect for a relaxing swim. The last stop is Shark Bay, where lucky snorkelers have reported seeing blacktip reef sharks and sea turtles, adding an extra thrill to the day.

Finally, the boat heads back to Mae Haad Pier, arriving around 5 pm, with a short transfer back to your hotel.

Authentic Encounters and Real Traveler Feedback

Many who have taken this tour rave about their guides and crew, describing them as friendly, knowledgeable, and helpful. One reviewer mentions, “All of the crew were fun and made sure we all had a good time,” which is key when navigating busy boat trips. The guides’ explanations seem appreciated, especially when they point out wildlife such as sea turtles and reef sharks.

The views from Nangyuan Island’s viewpoint are often described as breathtaking, with one traveler calling it “one of the most beautiful you will ever see”. The snorkeling spots receive high praise, with many reviews mentioning colorful fish, corals, and sightings of turtles. One visitor even shared, “We saw 2 turtles, anemones, and so many amazing fish. Loved it,” highlighting the richness of marine life.

Satisfying the appetite is another strength outlined by reviews—the Thai lunch and snacks are considered tasty and enough to keep you energized for the day. For example, one comment mentions, “Lunch and snacks were nice,” which is a nice plus given the full day of activity.

However, not all feedback is glowing. Some reviews mention overcrowding, noting that managing over 100 people can make the experience feel a bit less intimate. Plus, there are concerns about food quality on certain days, and a few travelers point out that the boat was different from what was expected or that some stops were missed due to weather.

Despite these, most guests find the value for money exceptional, especially considering the multiple snorkeling sites, viewpoint, lunch, and hotel transfer included in the price. This makes it a cost-effective way to experience a variety of Koh Tao’s top sights without organizing each piece separately.
