Koh Racha: Phuket's Hidden Gem Island

Discovering Koh Racha

Koh Racha, also spelled Raya, is actually two islands located about 12 kilometers south of Phuket: Racha Yai (Big Racha) and Racha Noi (Little Racha). While most tourists flock to the Phi Phi Islands or Phang Nga Bay, Koh Racha offers a quieter, equally beautiful alternative with some of the clearest water near Phuket.

Racha Yai is the more developed of the two islands, with a few small resorts, restaurants, and a gorgeous crescent-shaped bay called Ao Tawan Tok (Batok Bay). Racha Noi is uninhabited and known primarily as a dive site. Together, they make for an excellent day trip or overnight stay from Phuket.

How to Get to Koh Racha

Speedboats to Racha Yai depart from Chalong Pier on Phuket's southeast coast. The crossing takes about 25 to 35 minutes depending on sea conditions. Several tour operators run daily group trips, or you can arrange a private speedboat charter for a more personalized experience.

Racha Noi is further south and takes about 50 to 60 minutes from Phuket. It is primarily visited by dive boats rather than general tour groups.

What to Do on Racha Yai

Beach Time at Batok Bay

The main bay on Racha Yai is Ao Tawan Tok, commonly called Batok Bay. It is a stunning U-shaped bay with fine white sand and crystal clear turquoise water. The water is incredibly clear here, often with visibility of 15 to 20 meters even from the surface. This is the primary beach where tour boats arrive and where you will find beach chairs, restaurants, and water sport facilities.

Snorkeling

Snorkeling off Racha Yai is rewarding. The eastern side of the island has coral reefs in good condition with plenty of reef fish. Common sightings include clownfish, porcupinefish, blue-spotted stingrays, and various wrasse species. Some tour operators also visit a sunken shipwreck that sits in shallow water on the island's southeastern side, which has become an artificial reef attracting schools of fish.

Scuba Diving

Racha Yai is one of the most popular dive sites near Phuket, especially for beginners and newly certified divers. Dive sites around the island include:

Bay 1 (Batok Bay): Shallow, calm, perfect for discover scuba dives. Depth 5 to 18 meters.
Bay 2: Staghorn coral gardens with seahorses and pipefish.
Bay 3: Good macro diving with nudibranchs and mantis shrimp.
The Harruby Wreck: A small deliberately sunk ship at 25 meters, covered in coral growth.

Siam Bay

On the northeastern side of the island, Siam Bay offers a quieter alternative to Batok Bay. It has fewer visitors and a more rugged, natural feel. The snorkeling here can be excellent when conditions are right.

Racha Noi: For Experienced Divers

Racha Noi is an uninhabited rocky island south of Racha Yai. It is known among divers for deeper sites (15 to 35 meters) with the possibility of encountering manta rays, especially between February and April. The currents can be stronger here, making it suitable for intermediate to advanced divers rather than beginners.

There are no beaches or facilities on Racha Noi. Visits are limited to dive boats that anchor offshore.

Costs

Group day trip (snorkeling): 1,500 to 3,000 THB per person including transfers, lunch, and equipment
Discover scuba diving (no certification needed): 3,500 to 5,000 THB per person for one or two dives
Fun dives for certified divers: 3,000 to 4,500 THB for two dives
Private speedboat charter: 20,000 to 45,000 THB per boat

Where to Stay

Racha Yai has a handful of accommodation options if you want to spend the night:

The Racha: A high-end resort with pool villas and a spa. Rates start around 5,000 to 15,000 THB per night depending on season and room type.
Budget bungalows: A few simpler options exist on the island starting from 1,500 to 3,000 THB per night.

Staying overnight lets you enjoy the island after the day trippers leave and experience the incredible stargazing with minimal light pollution.

Best Time to Visit

Racha Yai is accessible year round, though the best conditions are from November to April. The water is clearest during these months with the best snorkeling visibility. During the rainy season (May to October), the sea can be rougher and visibility slightly reduced, but tours still operate on most days.

Why Choose Koh Racha Over Other Islands?

Here is why Racha stands out:

Fewer crowds: Less touristed than Phi Phi or Coral Island
Short travel time: Just 30 minutes from Phuket
Excellent diving: One of the best beginner dive sites in Thailand
