6 Best Diving Sites

1. Mu Ko Similan National Park offers the best of Thailand’s scuba diving experience. Underwater sceneries vary from towering boulders appearing like city-scapes to colorful coral reefs flooded with marine life. The visibility is usually excellent and the abundance and variety of aquatic animals are second to none. The best way to dive and hop around Similan is from the liveaboard boat.

2. Ko Lipe, located in southern Thailand’s Satun Province near the Thailand/Malaysia border, offers some excellent diving sites and picturesque white-sand beaches dotted with coconut trees. Found at the southern end of Thailand, leopard sharks, whales, dolphins, and manta rays sweep against a backdrop of colorful soft coral, rock formations, pinnacles, and boulders.

3. Ko Phi Phi is famous for its beautiful beaches, made even more so by Hollywood’s blockbuster “The Beach.” It is also notable for the vivid soft corals and sea fans.

4. Ko Tao is a tropical paradise with white sand beaches fringed with palm trees, rugged cliffs, and stunning sunsets. It is fit for all levels of scuba diving. The underwater scenery is spectacular coral encrusted rock pinnacles, vibrant reefs, and some great shipwrecks—whale sharks and spotted eagle rays are often seen horsing around. Ko Tao is also very close to Ko Samui and Ko Pha-ngan, making it easy to visit all three islands in one trip.

6. Ko Lanta, part of the Krabi province, has a feel-good vibe perfect for a young traveler’s spirit. Its clear waters, mangroves, white sand beaches, and lush rainforests are stunning. The underwater spectacle is easily accessible by slow boats and is populated with whale sharks, manta rays, and vibrant reefs.

Freediving in Thailand | Image Credit: Shutterstock


Like the old days when fishermen dove to the bottom of the sea to collect sponge, pearls, or seashells in one breath of air, freedivers plunge into the ocean for a deeper silence and sophisticated beauty.

Freediving is now practiced widely as a leisure sport and is gaining mainstream interest. Many people are choosing to cast off clunky diving gear in favor of this form of diving. Go under the sea to have a full view of colorful marine animals and embrace the peaceful feeling of weightless freedom. Ko Tao and Phuket are popular entry points to this deep and meaningful adventure.
