Ko Pha Ngan isn’t just famous for its Full Moon parties—it’s also a fantastic place for snorkeling. The island’s clear waters, vibrant coral reefs, and nearby smaller islands make it a prime spot for underwater adventures. We especially like the Koh Phangan Snorkelling Cruise with Sunset for its scenic stops and relaxed vibe, and the Koh Tao & Koh Nangyuan Snorkeling Trip By Speedboat for its unforgettable island scenery and lively reef life. Whether you’re after a peaceful day exploring coral gardens or an action-packed boat trip, Ko Pha Ngan offers something for every snorkeler.
For those who want a comprehensive experience with well-organized stops and guides, the Koh Tao & Koh Nangyuan Snorkeling Trip is a standout. If you’re more interested in a shorter, budget-friendly day with multiple snorkeling spots, the Koh Phangan Snorkelling Cruise with Sunset fits the bill. And if you’re keen on exploring more remote, less crowded reefs, the Koh Tao and Nang Yuan Snorkeling Day Trip provides a full-day adventure that covers both land and sea.
1. Koh Phangan Snorkelling Cruise with Sunset
At number 1, the Koh Phangan Snorkelling Cruise with Sunset offers an 8-hour day sailing around the island and neighboring Koh Tao. It’s a relaxed way to see some of the best snorkeling spots, with stops at two distinctly different locations. The first stop is all about swimming, snorkeling, and jumping off the boat, with the added fun of doing some fishing while anchored. The second stop takes you to a pristine beach and snorkel area that feels like stepping back in time, with untouched sands and clear waters perfect for peaceful exploration.

At number 2, the Koh Tao & Koh Nangyuan Snorkeling Trip offers a full-day adventure that combines island-hopping with some of the most stunning underwater and above-water scenery in the region. This tour begins with a quick transfer from Ko Pha Ngan to Koh Tao, a small island known for its excellent diving and snorkeling spots. The itinerary includes visits to Mango Bay, Hin Wong Bay, and the famous Nang Yuan Island, where three islands are joined by a white sandbar.
The trip shines because of its variety—visiting different beaches and reefs, enjoying snorkeling and swimming, and ending with a buffet lunch on Nang Yuan.

3. Koh Tao and Nang Yuan Snorkeling Day Trip from Koh Pha Ngan
The third option, the Koh Tao and Nang Yuan Snorkeling Day Trip, offers an all-day speedboat journey with plenty of snorkeling opportunities. Starting with hotel pickup, the tour heads directly to Koh Tao, where you can snorkel among vibrant reefs full of colorful fish and corals. Afterward, the trip continues to Koh Nang Yuan—famous for its three connected islands and white sandbars—where you can relax or snorkel in the calm, shallow waters.
This trip is rich in options, allowing you to see both reef ecosystems and scenic islands. While reviews are sparse, the focus on snorkelling combined with the relaxed beach time makes it appealing.
