The Itinerary: What You Can Expect

Morning Pickup and Departure

The tour begins around 09:00 am with hotel pickup (except for Mango Bay and Lighthouse Beach, which are not included in the transfers). The group heads from Mae Haad pier to Koh Nang Yuan, with the boat departing promptly at 10:00 am. The early start is ideal for maximizing the day, and the group size caps at 50 travelers, keeping the vibe lively but not overcrowded.

Koh Nang Yuan Island: The Highlight

The very heart of this trip is Koh Nang Yuan. You’ll get around an hour to walk on the famous sand bridge that connects the three tiny islands—an Instagram-worthy shot waiting to happen. You can also hike to a viewpoint for panoramic vistas of the surrounding islands, a must for photography lovers.

The “Japanese Garden” snorkeling point on Nang Yuan is often praised for its vibrant coral and abundant fish. Reviewers like Adam_W mention that the crew ensures everyone gets good snorkel time and help spotting marine life. The guide’s attentiveness makes the experience more reassuring, especially for less experienced snorkelers.

Mangrove Bay and Coral Gardens

After returning to the boat, a lunch box and fresh fruits are served—reviewers note that the food is both plentiful and tasty, with some mentioning the good quality of the ingredients. Post-lunch, you’ll snorkel at Ao Muang, famous for its beautiful corals and diverse fish populations. Here, the underwater scenery is often described as stunning, with bright coral, colorful fish, and occasional sightings of sea turtles.

Hin Wong Bay and Aow Leuk Beach

Next, the boat takes you to Ao Hin Wong, where millions of yellow-striped scad fishes gather—an incredible sight for underwater photographers and fish lovers alike. Reviewers like Tom_B mention algae sometimes being present, which can be a minor annoyance but not a deal-breaker.

Aow Leuk Beach is the next stop, known for its large corals and calm waters. It’s a quieter, more relaxing spot to unwind or snorkel a bit longer. Travelers like Rachael_M appreciate the chance to see a variety of marine life, including larger fish and the occasional turtle.

Shark Bay: The Exciting Finale

The last snorkeling stop is Shark Bay, which lives up to its name with the chance to spot green turtles and, if luck is on your side, blacktip reef sharks. Guides often point out marine creatures actively swimming around, and many reviewers have been thrilled to see sharks and turtles in their natural habitat, as Raanah_M describes.

Return to Nang Yuan and End of Tour

Your final hour is back on Koh Nang Yuan, where you can revisit the viewpoints or dip your toes at the sandy beaches. This spot is a perfect way to wind down, take photos, or just relax after a day full of activity.

Why This Tour Offers Excellent Value

At just over $30, the price point is attractive considering everything included—snorkel gear, life jackets, lunch, drinks, transfers, and guides.

The boat itself is described as basic but very accommodating, with facilities like a roof terrace, toilet, and a slide that kids and adults alike enjoy.

The experience is designed for groups, which keeps the vibe lively and social. The guides are praised for their energy and helpfulness, with some reviews highlighting specific team members like Matthew for their effort in making sure everyone has a good time and sees the marine life.

Additional Perks and Practicalities

• The snorkeling equipment is provided, so no need to bring your own gear unless you prefer personal masks or fins.
• The group size allows for intimate encounters but still offers the lively energy of a larger tour.
• The timing suits those who want a full day without feeling rushed, with the tour lasting approximately 6-7 hours.
• Be aware of the national park fee (250 THB for adults, 150 THB for children), payable at entry, which is a common fee for marine parks in Thailand.

Some reviewers noted that booking through Viator could be more expensive than directly through the operator, so it’s worth checking the actual price with the tour provider if budget is a concern.
