Had an AMAZING experience on our guided jet ski tour. Our guide took us around parts of the island and took pictures for us. I'm glad we had a guide instead of going by ourself because our guide was able to take us to a spot that had a pod of dolphins. It was a breathtaking moment. Thanks Chris for getting this trip organized for us. I highly recommend Samui Luxury Boat.

Wow, where do I start. From the very first enquiry Chris was awesome. No request was too big or too hard. We hired the cat to celebrate my wife's birthday and Chris made sure every detail was perfect. I even threw in some last minute requests, again we're no hassle for Chris. The staff on the boat yesterday, Mr GET and his team were amazing, catering to everyone on board glasses were always full. The food was cooked perfectly and very well presented and most importantly tasted amazing. I can't say enough good things. To sum it up, Samui Luxury Boat is a must do. You will not be disappointed. Thanks again to Chris, GET and the team.

Koh Samui Scuba Diving and Snorkeling FAQs

Is Koh Samui good for scuba diving?

Koh Samui is a prime spot for scuba diving, with its warm waters hosting diverse coral reefs and exotic marine life. Divers of all levels can enjoy vibrant coral gardens, tropical fish, and encounters with turtles and reef sharks. The island caters to beginners and advanced divers alike, offering a chance to explore underwater wonders.

The variety of dive sites in Koh Samui includes shallow reefs for novices and deeper areas for seasoned divers. Famous spots like Sail Rock and Chumphon Pinnacle are easily accessible, with Koh Tao just a boat ride away. Favorable diving conditions, with warm water temperatures and good visibility, enhance the experience. Dive centers across the island provide equipment, guided dives, and certification courses, ensuring a safe and memorable diving adventure for everyone.

Is Koh Samui good for snorkeling?

Koh Samui in Thailand is a top spot for snorkeling, thanks to its crystal-clear waters and rich marine life. The island’s excellent visibility lets you see vibrant coral reefs and a variety of sea creatures. Expect to encounter colorful fish like butterflyfish and parrotfish, as well as sea turtles and small sharks. This underwater clarity makes the experience like exploring a live aquarium.

The island’s snorkeling sites are easily accessible, with popular spots like Koh Tan, Koh Matsum, and Angthong Marine Park just a short boat ride away. These locations offer varying depths suitable for both beginners and experienced snorkelers.

Does Koh Samui have coral reefs?

Koh Tan, just off Koh Samui’s southern coast, is a notable snorkeling and diving destination. This small island offers shallow coral reefs teeming with diverse fish and marine life, perfect for underwater exploration. Another must-visit is Ang Thong Marine Park, a cluster of islands northwest of Koh Samui. While not directly on Koh Samui, it’s a favored day trip spot. The park features stunning coral reefs ideal for snorkeling and diving.

When can you see whale sharks in Koh samui?

If you’re hoping to see whale sharks during your trip to Koh Samui, Thailand, there are a few things to keep in mind. The ideal time for sightings is from February to April, aligning with the dry season and better water visibility. Whale sharks, being migratory, follow food sources like plankton blooms, which influences their presence in the area.

Koh Samui is near the Ang Thong Marine National Park, a hotspot for diverse marine life, though whale shark sightings there are not a certainty. To boost your chances, consider a snorkeling or diving trip with experienced guides who know the best spots.

Where is the clearest water in Koh Samui?

Koh Samui’s Silver Beach, hidden away from tourist crowds, offers a peaceful retreat with stunningly clear waters. Known locally as Haad Thong Ta-khian, this beach remains unspoiled, free from large resorts and commercialization, preserving its natural charm and water clarity.

Silver Beach is not only known for its clear turquoise water but also for its tranquil setting and white sandy shores. Easily accessible, yet secluded, it’s a perfect spot for relaxation, swimming, and enjoying nature’s beauty, complete with basic amenities and a serene atmosphere.

For the clearest waters, charter a boat to Ang Thong National Marine Park, Koh Tao or Koh Phangan.

Which part of Koh Samui has the best beaches?

Koh Samui in Thailand offers a variety of beaches, each with its unique charm. Chaweng Beach, on the east coast, is vibrant and popular, known for its crystal-clear waters and active nightlife. It’s perfect for those looking for a lively beach experience with plenty of amenities.

For a quieter setting, Maenam Beach in the north provides a serene atmosphere, ideal for relaxation. Lamai Beach, on the southeastern coast, combines stunning scenery with a laid-back vibe, famous for its unique rock formations. Upscale Bophut Beach, in the Fisherman’s Village, offers luxury with boutique resorts and trendy spots, plus a vibrant Friday Night Walking Street. Each beach in Koh Samui caters to different preferences, whether it’s lively activity, peacefulness, natural beauty, or luxury.
