Koh Tao & Koh Nangyuan by Speed Boat (Snorkeling trip from Koh Samui)

If you’re planning a day of snorkeling around Koh Tao and Koh Nang Yuan from Koh Samui, this tour promises a lively, efficient way to see two of Thailand’s most beautiful islands. We’ve looked into this experience, and it’s perfect for travelers who want to maximize their time with vibrant coral reefs, connecting islands, and a hassle-free experience.

Two things we love about this trip are the inclusion of snorkeling gear—making it easier to jump straight into the water without extra fuss—and the buffet lunch by the beach, which keeps you energized for the afternoon adventures.

On the flip side, a potential consideration is the large group size, which might make the experience less intimate for some.
This tour is well-suited for those who value convenience, value for money, and a relaxed approach to island hopping.

It’s especially appealing if you’re looking to tick off multiple snorkeling sites in a single day without the logistical headaches.

Key Points

• Quick access to Koh Tao and Koh Nang Yuan via speedboat saves you hours of travel time.
• All necessary snorkeling equipment is included, removing the need to rent gear separately.
• The buffet lunch offers a convenient and tasty break with beachfront views.
• Multiple snorkeling sites provide a variety of underwater scenery.
• Group size can be on the larger side, which may affect the feeling of intimacy.
• Entrance fees at Koh Nang Yuan are not included, so budget accordingly.

The Journey Begins: Picking Up and Setting Out

The adventure begins early, with pickup from your Koh Samui hotel—an advantage for those wanting to avoid the hassle of finding the pier. The check-in process is straightforward, and the crew offers a quick briefing to set expectations. We appreciated how professional and friendly the staff appeared, making the start of the day smooth.

Once aboard the speedboat, you’re in for a roughly 1.5-hour ride across the water. The boat itself is a standard speed vessel, equipped with three engines—that’s necessary for the safety of larger groups crossing open water, especially to distant Koh Tao. The ride might feel a bit more bustling if the boat is full (up to 75 travelers), but most reviews note the ride is generally comfortable, and the views of the coastline and ocean are breathtaking.

First Stop: Snorkeling at Mango Bay (Ao Muang)

The initial snorkeling site, Mango Bay, is a highlight. The coral reefs here are spectacular, teeming with colorful fishes and lively marine life. We loved the way the crew pointed out the best spots to see the most marine creatures and gave tips on snorkeling techniques. Reviewers like Pleun_P praised the staff, saying, “Good staff and the pickup service is perfect! Food was also very nice. We went to 3 different spots.”

The clarity of the water and the variety of fish—some reviewers mention hundreds of different species—make this spot perfect for both beginners and more experienced snorkelers. Entrance fees for Koh Nang Yuan, where the tour continues later, are not included here, but the reef itself offers ample underwater spectacle for free.

The Lunch Break: Beachfront Buffet

After a fun morning in the water, the tour includes a buffet lunch at a restaurant on the beach. Many reviews highlight the quality of the food—pleasing, plentiful, and served with a view. Irene_C described it as a “great buffet lunch,” and many appreciated the chance to rest and refuel before the afternoon.

Having food included is a real plus for travelers who prefer a stress-free, all-in-one package. It saves time and money compared to eating independently, and the beachfront setting adds to the relaxed vacation vibe.

Exploring Koh Nang Yuan

Post-lunch, the trip heads to Koh Nang Yuan, a chain of three connected islands with long sandy beaches—one of the most photographed spots in the region. Here, you have free time to snorkel more, relax on the beach, or hike up to the viewpoint. The view from the top offers a stunning panorama, perfect for photo enthusiasts.

However, a word of warning: some travelers mentioned that Koh Nang Yuan charges an entrance fee (THB 250 for adults, THB 120 for children), which is not included in the tour price. Also, beach chairs and umbrellas are not included, so bringing your own or preparing to sit on the sand is advisable.

Many reviewers, like Ilona_K, enjoyed the opportunity to see hundreds of fish and the clear waters. Others appreciated the slow pace, describing the experience as “very relaxed” and “not rushed,” which is ideal if you want to savor the scenery.

The Return Trip

The journey back to Koh Samui is straightforward, with the boat departing Koh Nang Yuan in the late afternoon, returning after about 1.5 hours. The crew often provides commentary during the ride, pointing out landmarks and sharing insights into the area’s marine life.

Most travelers find this trip to be well-organized and efficient, especially considering the long-distance travel involved.

Included:
– Round-trip transfers from your hotel, which simplifies logistics.
– Snorkeling equipment, so you can jump right in without worrying about gear.
– Buffet lunch and soft drinks—great for staying energized.
– Full tour insurance coverage, so you’re protected during your water activities.

Not Included:
– Entrance fees at Koh Nang Yuan (THB 250 for adults, THB 120 for children).

Knowing these details helps you budget and plan your day better.

This trip is ideal for travelers looking for efficient island hopping with inclusive amenities. If you prefer to avoid the hassle of organizing multiple transport legs, the all-in-one package offers good value. It’s also suitable for those who love snorkeling in clear waters and want to visit two very photogenic islands without spending a fortune.

However, if you prefer a smaller, more intimate group or highly personalized service, the larger group size might be a drawback. Also, if you’re sensitive to crowds or want to avoid additional entrance fees, consider the extra costs at Koh Nang Yuan.

It’s not tailored for cruise ship passengers who have limited time or for travelers seeking a more private, boutique-style experience. Still, for most independent travelers or families, it hits the right notes of adventure, convenience, and value.

This snorkeling trip from Koh Samui to Koh Tao and Koh Nang Yuan offers a solid value for those eager to explore multiple sites with minimal fuss. The included snorkeling gear and buffet lunch add to the convenience, and the scenic boat ride itself is part of the fun.

Many travelers praise the knowledgeable guides, the stunning underwater landscapes, and the friendly crew that makes the day smooth and enjoyable. The large group size may feel a tad hectic at times, but the experience remains lively and engaging.

If you’re after a day of relaxed snorkeling, beautiful vistas, and simple logistics, this tour delivers. Just remember to bring some cash for the entrance fee at Koh Nang Yuan, and maybe a hat and sunscreen for the time on the beach.
