Koh Racha Yai Island

Koh Racha Yai is one of the most popular scuba diving and snorkeling destinations near Phuket. Just a short boat ride from Chalong Pier, the island is known for its crystal-clear waters, shallow coral reefs, and white sandy beaches. These calm conditions make it the perfect site for beginner divers, Discover Scuba Diving (DSD), and PADI Open Water Courses.

Divers can explore shallow bays filled with colorful reef fish, hard corals, and artificial reefs such as sunken scooters and reef blocks. For more experienced divers, deeper sites around the island offer chances to see barracuda, stingrays, and sometimes turtles. Snorkelers can enjoy the island’s lagoons and beaches, where the water is calm year-round.

Racha Yai is often combined with trips to Racha Noi or Maithon Island, making it a great choice for both half-day and full-day adventures. Whether you’re trying scuba diving for the first time, taking your first certification, or simply snorkeling with family, Racha Yai offers a safe, fun, and beginner-friendly underwater experience in Phuket.
