Excellent value! We had high seas and they had to skip the 5th stop, but still WELL worth it - saw lots of coral, a couple baby sharks and a giant leatherback turtle. Friendly, competent, professional crew made the trip amazing, and the free photos captured great memories. Clean, well maintained, comfortable ship and a delicious lunch were a huge plus as well. All in all - don't miss it.

Awesome

Very well-organized excursion, excellent snorkel equipment (fins were not included in our tour), good Thai buffet, the staff behaved incredibly with our son Max and guided us so we could see the blacktip reef shark and a sea turtle in their habitat. I would repeat with them without hesitation

The maximum for a small amount of money, a great experience for the family

We did not expect much from the tour; it was just intended to be a little change of pace. We enjoyed the entire tour all the more; there is enough time to explore the individual areas, and everything from small sharks to turtles was included. The staff were very friendly and ensured a pleasant atmosphere during the trip. There were plenty of photos available after about 2 hours, free of charge. I just didn't find the food to be anything special, but at that price, you can overlook it. Booking on-site is significantly cheaper than through the platforms.

Full day snorkeling adventure around Koh Tao

Wonderful experience

We started the day by picking up the others at their hotels. We made our first stop to visit Koh Nang Yuan and its viewpoint, then we made a snorkeling stop, and afterwards they gave us a delicious lunch. We saw turtles, a baby shark, fish, and beautiful corals. The instructors were very kind and explained to us at all times where to head to see them. 100% recommended experience.

Koh Tao Snorkeling Tour to Hidden Bays and Koh Nang Yuan

Good day

We participated in the excursion to visit the surrounding islands. Superb adventure, the boat is great, the team just as much. The meal is provided and of good quality. The tour is smooth, masks and snorkels provided, several spots to dive, swim, see the marine life, all that at a more than affordable price for the service rendered. I recommend 🤙

Ko Tao: Vintage Boat - Small Group Snorkeling Day Trip with Meals

Voyage49962854752, Jan 2026

Unforgettable day - highly recommended!

Unforgettable day – highly recommended! We had a fantastic time on the SunSet Magic Snorkeling Tour around Koh Tao and to Koh Nangyuan – everything just fit perfectly! From the hotel pickup service throughout the day we felt super looked after and supported. Snorkeling at several impressive spots was a real highlight – the corals and fish world around the islands are simply beautiful. The crew was friendly, professional and always attentive, and we even got underwater photos, which makes the memory of that day even more special. The lunch buffet on board was delicious and rich, and the BBQ dinner at sunset was the perfect end to the day – with breathtaking views and great atmosphere. We especially loved the small, personal group (we were only nine people on board), which made the day cozy and relaxed – no comparison to crowded large boat tours. 💯 Top Tour, great team and a great success – we can highly recommend this experience to everyone!
