If you’re dreaming of exploring Koh Tao’s vibrant marine life without the crowds, the First Light Snorkel Adventure with Oxygen Tours offers a compelling option. For just $35 per person, this half-day trip takes you around some of the island’s most beautiful and lesser-visited spots, starting early when the waters are calm and the world is quiet. It’s a refreshing way to see Koh Tao’s underwater beauty, with stops at Tao Thong, Freedom Bay, Ao Leuk, and Shark Bay.
Two things we really like about this experience are the intimacy of small groups, which means less jostling and more personalized guidance, and the chance to snorkel in pristine waters before the tourist rush arrives. Plus, the fresh Thai lunch served aboard the boat adds a nice touch of local flavor. One consideration is that the tour might not suit travelers with limited mobility or those looking for a full-day adventure, as it’s focused on a peaceful, morning experience.
This tour feels perfect for anyone who loves quiet, scenic snorkeling and appreciates expert guides. It’s especially appealing for those who value small group atmospheres and want to explore Koh Tao’s underwater world in a relaxed, unhurried way.

What makes this tour stand out?

Itinerary Breakdown

Next, you’ll visit Freedom Bay, known for its secluded and tranquil waters. Here, the focus is on enjoying the peace while spotting more marine creatures and reef formations. The reviews echo the appreciation for having undisturbed time at each stop.
Ao Leuk: The Playful Bay
Cruising on, you arrive at Ao Leuk, renowned for its inviting waters and lively schools of fish. Swimmers and snorkelers here often mention how calm and clear the waters are, perfect for relaxing and observing aquatic life. Expect to see schools of fish darting around in the gentle currents, making it a favorite for many.
Shark Bay: The Highlight
The final stop is at Shark Bay, one of Koh Tao’s most famous snorkel sites. Despite its name, encounters with sharks are usually of the harmless, reef-shark variety, and sightings are generally a bonus, not a guarantee. Still, many reviewers have been lucky enough to see baby sharks or other marine creatures during their visit. The marine life spectacle here is often described as “underwater ballet”, with fish and other species gracefully moving around.
Lunch and Return
After the snorkeling, it’s time to relax and refuel with a fresh Thai-style lunch, served onboard. The meal is described as healthy and authentic, with vegetarian options available. This adds a satisfying finish to your morning adventure, allowing you to enjoy your meal while cruising back to Mae Haad Pier.
What’s Included & What to Prepare

The package covers round-trip hotel transfers, snorkeling equipment, life jackets, beach towels, and toilets onboard—making it both convenient and low-stress. The light breakfast, water, coffee, tea, and fresh fruits provide a good energy boost for the morning’s activities.
Travelers are advised to bring sunscreen (biodegradable), sun protection gear, a camera or smartphone (preferably waterproof), and change of clothes. Since large luggage isn’t permitted, pack light with essentials stored in a waterproof bag.
What to Expect: The Real Experience

From reviews, it’s clear that the biggest draw is quality over quantity. The tour’s small size usually means just your group and guides, which enhances the feeling of privacy and allows guides to give more detailed attention. Many guests describe seeing turtles, baby sharks, and colorful reef fish, which makes the experience feel genuinely special.
The guides’ enthusiasm and attentiveness are consistently praised. One traveler noted how the calm and serenity of the morning made the experience more meaningful, emphasizing that this is more than just a snorkel trip — it’s a peaceful escape.
Potential Drawbacks

While the tour offers a relaxed, immersive experience, it’s not suitable for everyone. The age restrictions and health considerations (for pregnant women, people with back or heart problems, or those over 70) reflect the physical demands of snorkeling. Also, if you’re looking for a full-day or more adventurous trip, this might feel a bit brief.
Some travelers noted that luck plays a role in marine sightings: encounters with sharks or turtles are not guaranteed, but the promise of exploring secluded, pristine waters remains valuable even without guaranteed wildlife sightings.
