Racha Noi Island is a small, nearly uninhabited island located in the Andaman Sea near Phuket. It is renowned for its pristine natural environment, crystal-clear waters, and diverse underwater world, making it a popular destination for snorkeling and diving enthusiasts. Unlike its larger neighbor Racha Yai, Racha Noi lacks developed tourist infrastructure, offering a more secluded and intimate experience for visitors seeking peace and proximity to nature.

The island’s shores are surrounded by picturesque coral reefs, and the seabed features a variety of landscapes, including sandy coves, hard and soft coral formations, and deep areas reaching up to 70 meters. These diverse underwater environments attract both novice and experienced divers alike, offering opportunities to observe manta rays, whale sharks, stingrays, and a wide array of tropical fish species.

The southern part of the island is famous for the South Tip dive site, known for frequent sightings of large manta rays and strong currents, making it a favorite spot for technical and advanced divers.

Racha Noi is an ideal destination for those who enjoy active water-based recreation combined with solitude and genuine natural beauty. The island is accessible by high-speed boat from Phuket, and yacht tours offer a luxurious way to explore hidden coastal spots and enjoy the tranquility of the tropical surroundings.
