Racha Islands: A Guide to Snorkelling and Diving

Green Racha Islands surrounded by clear blue sea south of Phuket

Racha Yai and Racha Noi: two tropical islands to explore on one day trip from Phuket.

Thailand Divers’ Racha Islands day trip includes both Racha Yai and Racha Noi. There is no need to choose between the islands.

This guide introduces snorkelling, scuba diving and the reef life around the Racha Islands, with practical ideas for enjoying your day on the water.

Planning a trip? This is a destination guide. Visit our Racha Islands diving day trip for current prices, inclusions and booking information.

Two islands on the same day trip

Racha Yai

Bays, reefs and relaxed exploring

Racha Yai is the nearer of the two islands. Its bays and reef areas offer a variety of profiles for training, reef exploration and certified-diver trips.

Selected sites can provide a comfortable setting for learning or rebuilding confidence when conditions are suitable.

Racha Noi

Island scenery and varied dive sites

Farther south, Racha Noi combines tropical reef sites with more exposed areas and deeper underwater features.

Some sites suit introductory programmes; others need more experience. Your instructor chooses an appropriate location and depth for the day.

Our day trip visits both islands. The captain and dive team choose the specific stops and order to suit the conditions on the day.

Snorkelling in the Racha Islands

A mask and snorkel let you enjoy the reef from the surface: look for colourful reef fish, coral formations and the changing shades of the water around the islands.

Enjoy the reef at your own pace

Use a comfortable mask and fins, and tell the team about your swimming confidence. Ask for flotation support if you need it and stay within the area explained in the briefing.

Give marine life plenty of room

Float above the reef without standing on coral or touching animals. Keep your fins clear of the seabed and follow the crew’s guidance about currents, entry points and returning to the boat.

If some of your group would like to snorkel while others dive, tell us when you enquire so we can confirm the arrangements and inclusions for everyone.

Slow down and look closely: small reef fish and changing coral textures are part of the experience.

Wildlife encounters

Turtles may pass through the reef, but every sighting is natural and should be enjoyed without chasing or touching.

Two islands, one day

The day combines the scenery of Racha Yai and Racha Noi, with the precise stops chosen for conditions.

Scuba diving in the Racha Islands

The islands are the destination; your experience determines the diving programme. First-time, certified and returning divers can enjoy suitable reef sites with the appropriate instruction or guiding.

Your first dive

Discover Scuba Diving

Start with an instructor-led briefing and skill practice, then explore suitable reef sites at your own pace. Our beginner programme visits the Racha Islands, with locations chosen for the participants and conditions.

What can you see underwater?

Look closely around the reef for tropical fish, moray eels, rays and small marine life. Coral gardens and underwater features make the Racha Islands rewarding even when larger animals are elsewhere.

Turtles and other larger visitors are possible, but wildlife sightings vary naturally. Watch without touching, keep clear of the coral and let animals choose their distance.

For more detail on the individual locations, read our Racha Islands dive-site guide.

Make the whole day work for you

A Racha trip is a day at sea as well as time underwater. Confirm your pickup area, equipment needs and current itinerary when you enquire.

  • Choose your programme: snorkelling, first dive, certified diving, refresher or course.
  • Share your experience: certification, recent diving and anything you would like help with.
  • Check your equipment: tell us which items you need and confirm what your package includes.
  • Plan your timing: allow for the boat journey, hotel transfers and your flight after diving.

Our Phuket weather guide, flying-after-diving guide and equipment guide can help you prepare.

Racha Islands questions

Does the day trip visit both islands?

Yes. Thailand Divers offers one Racha Islands day trip that includes both Racha Yai and Racha Noi. You do not choose between separate island trips. The specific stops and their order are selected for conditions on the day.

Can I enjoy the islands without scuba diving?

Snorkelling offers a way to enjoy the reef from the surface. Tell us your preferred activity and swimming confidence when you enquire, and we’ll confirm the arrangements for your group.

Can beginners dive at Racha Noi?

Suitable Racha Noi reef sites can be used for introductory diving. More exposed or deeper sites are a different proposition. Book the beginner programme and let your instructor choose an appropriate site and depth.

Is a diving certification required?

Certified-diver trips require certification. First-time divers can choose Discover Scuba Diving, which provides instruction and supervision without requiring an existing certificate. It does not award a full diving certification.

Should I take a refresher before the trip?

Tell us when you last dived and how confident you feel. We can help you decide whether the private refresher is the most comfortable way to return.
