This Snorkel Trip to Koh Nangyuan and Koh Bays offered by Oh-Hoo promises all that and more—ranging from visits to stunning, hard-to-access spots to a comfortable, well-equipped boat experience.
We’ve looked at the details, reviews, and itineraries to help you decide if this adventure is worth your time and money.
What really stands out about this tour is the balance between multiple snorkeling sites and a smooth, hassle-free setup that includes equipment, transfers, and a tasty Thai lunch. The price point—just under $30 per person—makes it an attractive option, especially considering the number of stops and the quality of the spots visited.
However, one thing to keep in mind is that the coral in some areas appears to be somewhat damaged or dead, a reflection of the global reef health issues, not necessarily the tour itself.

Starting Out: Easy Pickup and Departure
The tour begins with convenient pickup from your accommodation in Koh Tao, which is a real plus for travelers who dislike navigating their way to a meeting point. The guides speak good English, which makes understanding safety instructions and snorkeling tips much easier. Once on board, the boat is equipped with restrooms, a roof terrace, and a GPS sounder, making the day both comfortable and engaging.
First Stop: Koh Nang Yuan and Its Iconic Sand Bridge
Most travelers highlight Nang Yuan Island as the trip’s highlight. This tiny island, connected by a sandbar, is famously picture-perfect. You can walk across the sand bridge that links three small islands, offering spectacular views and great photo opportunities. The “Japanese Garden” snorkeling point, situated nearby, is often praised for its vibrant marine life and coral formations.
One traveler notes, “The trip was mostly people in their 20s but staff made sure all ages could participate,” which underscores how well the guides cater to a varied group. The viewpoint atop Nang Yuan offers panoramic vistas that are well worth the climb, and the shallow waters around this area make for an ideal snorkeling spot for beginners.
Mango Bay: A Tasty Break and Marine Riches
After exploring Nang Yuan, the tour provides a Thai-style lunch box, a surprisingly decent meal that many reviewers mention positively. Unlike some excursions that just serve basic snacks, this lunch adds value to your day, allowing you to relax and refuel.
Post-lunch, the adventure continues with snorkeling at Ao Muang, where the coral reefs are beautifully vibrant, populated with a variety of fish. This site is praised for its abundance of colorful marine life, offering a visually stunning underwater scene.
Ao Hin Wong: Watching Tens of Thousands of Fish
Next, the boat heads to Ao Hin Wong, renowned for the spectacle of millions of Yellow-Strip Scad fishes. If you love watching schools of fish swirling in unison, this spot is a highlight. The experience is often described as “magical,” and it’s a great chance to see fish in large numbers, though the coral here is not as vibrant as other sites.
Ao Leuk: Big Corals and Diverse Fish
The journey then takes you to Ao Leuk, famous for its large coral formations and colorful fish. Reviewers often mention the size of the corals here—something that adds a sense of awe. The protection of this site means you’ll get to see a variety of marine species, though some note that parts of the coral are showing signs of distress, likely due to environmental factors.
Shark Bay: Turtles and Sharks
The final snorkeling spot, Shark Bay, is often cited as a “must-see,” especially for the chance to spot green turtles or, on lucky days, blacktip reef sharks. While sightings aren’t guaranteed, the possibility adds excitement. One reviewer called it “the last highlight,” and many are pleasantly surprised at how close they can get to these gentle creatures.
Return to Nang Yuan and Wrap-up
The tour wraps up with about an hour at Nang Yuan, giving you time to enjoy the iconic scenery, walk on the sand bridge, or take more photos. The guides are known for their friendliness—some even take free GoPro photos, which many travelers praise.
What Makes This Tour Stand Out?
The combination of multiple stops—from the famous Nang Yuan to the vibrant coral reefs and the chance to see turtles—is what really makes this a good value. The logistics are well handled, with pickups and comfortable facilities onboard, allowing you to focus on enjoying the underwater world.
The guides are another highlight, with reviews mentioning their good English skills and attentive nature. They explain safety rules clearly—“don’t stand on the coral,” one review reminds us, which shows the team’s commitment to conservation awareness.
The gear and safety equipment—including life jackets—are provided, removing a common hassle for travelers. The boat’s roof terrace and onboard toilets make the long day more comfortable, especially when you’re out on the water for around 6-7 hours.
The Value of the Price

At around $29, this tour offers remarkable value considering the number of snorkeling stops, the included lunch, equipment, and transfers. When you compare it to similar experiences, the price seems reasonable, especially given the positive reviews of the guides, safety, and overall organization.
However, it’s worth noting that the coral conditions at some sites are not pristine, which is a reflection of broader environmental issues. Still, the marine life you see, like turtles and schools of fish, can be impressive.
Who Is This Tour Best Suited For?

This trip is ideal for travelers who want a full day of snorkeling without the stress of planning individual outings. It’s perfect for families, first-time snorkelers, and experienced swimmers alike, thanks to the provided gear and guided instructions. It’s also well-suited for those on a budget but eager to explore multiple underwater sites.
If you’re looking for a relaxing day with diverse marine scenery, friendly guides, and good value, this tour ticks those boxes. But if your main concern is pristine coral or rare marine species, be aware that some sites have seen coral damage.
