Racha Island – known in Thai as Koh Racha, also called Raya Island – lies just 12 kilometres south of Phuket and is one of the least crowded, most beautiful islands in the region. Crystal-clear turquoise water with visibility up to 30 metres, pristine white sand at Patok Bay, and some of the best snorkeling conditions anywhere near Phuket. Unlike the busy Phi Phi Islands or even Coral Island, Racha Island Phuket has stayed quieter and more natural – no jet skis, no parasailing, no party scene. What it does have: water buffalo wandering the jungle paths, small family resorts including the five-star The Racha, four distinct bays each with their own character, and a diving reputation that draws visitors from across Asia. Suitable for families, beginners and experienced divers alike.
When people say Racha Island, they typically mean the two islands of Koh Racha Yai (the large one) and Koh Racha Noi (the small one) – together forming the finest snorkeling and diving destination directly off Phuket’s south coast. Both islands lie in the Andaman Sea and are reached by speedboat from Chalong Pier.
Koh Racha Yai is the larger, inhabited island and the destination for all day trips.
It combines multiple white sand bays, calm water, excellent snorkeling and a handful of small resorts – most notably the award-winning The Racha (5-star) and the family-oriented Ban Raya Resort. There are no jet skis here, no parasailing stations, no loud music. Instead: water buffalo moving through the jungle, fresh seafood at beachside tables, and an atmosphere that still feels like the Thailand of twenty years ago.
Koh Racha Noi is smaller, uninhabited and has no beaches.
It is a specialist diving destination – deeper reefs, greater species diversity, and from January to March, near-guaranteed manta ray sightings. Only experienced divers and specialist dive boats visit Racha Noi; for snorkelers and day-trippers, Racha Yai is the correct destination.
Koh Racha Yai has no bad beaches – but each bay has its own atmosphere and suits different activities. Here is a detailed overview:
Around ten minutes’ walk from Patok Bay, Siam Bay on the island’s north side is considerably calmer – fewer boats, less infrastructure, more nature. Anyone wanting to escape the energy of the main beach finds genuine tranquillity here, with clear water and a relaxed atmosphere that contrasts sharply with Patok’s midday bustle.
Kon Kae Bay, directly in front of Ban Raya Resort, is consistently rated the finest snorkeling spot on the entire island. A large colony of hard corals shelters an exceptional diversity of reef fish – you enter from the beach, no boat needed. The bay is sheltered from wind and is accessible even during the low season, making it one of the few spots near Phuket that often remains diveable in poor weather.
Just three minutes’ walk from Ban Raya Resort, Ter Bay is particularly worth knowing in the low season: sheltered, calm, soft sand and clear water. Sun loungers and a small snack bar are available. When surrounding beaches are closed due to weather, Ter Bay is often the only one still accessible – making it a genuine year-round option and a worthwhile detour at any time.
Racha Island ranks among the best snorkeling and diving destinations near Phuket – and for good reason. Underwater visibility far exceeds most other day-trip islands, the water is calm and the reef is accessible directly from the shore without a boat.
Patok Bay and Kon Kae Bay are both excellent for first-time snorkelers: shallow water, minimal current, and strong visibility.
Just a few metres below the surface: colourful hard corals, pufferfish, parrotfish and the full palette of reef inhabitants. Sea turtles are regularly spotted with patience – and the lucky few encounter a small reef shark.
For experienced divers, Racha Island is a fixed stop on the...
Phuket dive circuit. Racha Yai offers several dive sites between 5 and 30 metres, suitable for all levels. Racha Noi is reserved for advanced divers: deeper dives, stronger currents, but larger marine life encounters. The headline: manta rays, which visit the waters around Racha Noi from January to March – an experience even seasoned divers describe as extraordinary.
The choice of vessel shapes the entire Racha Island day trip experience. Both options have clear strengths – here is an honest comparison:
The speedboat from Chalong Pier reaches Racha Island in approximately 30–40 minutes…
– the fastest way there and back. More time for snorkeling, swimming and relaxing on the beach. The speedboat is the standard and most popular option for day trips to Racha Island. Just a few metres below the surface: colourful hard corals, pufferfish, parrotfish and the full palette of reef inhabitants. Sea turtles are regularly spotted with patience – and the lucky few encounter a small reef shark.
The catamaran offers more space, a smoother and more stable crossing, and a more relaxed on-board atmosphere
– ideal for families with young children or anyone who wants the journey itself to be part of the experience. Travel time is longer (approximately 60–90 minutes each way), but the views of the coastline and the sailing experience compensate. Often combined with a stop at Coral Island.
Our verdict: Speedboat = more time on the island. Catamaran = more comfort on the water. For snorkeling enthusiasts, the speedboat is the better choice. For families with young children or those who prefer a calmer crossing, the catamaran wins.
Air-conditioned minibus pickup from your hotel in Patong, Kata, Karon or Phuket Town. Typical pickup times between 08:00 and 09:00 depending on location. Drive to Chalong Pier: 15–45 minutes. At the pier: check-in, brief safety information and snorkeling equipment distribution.
Approximately 30–40 minutes across the Andaman Sea. The water turns progressively clearer as you approach – the silhouette of Racha Yai's green hills and white sand bays visible long before arrival. First view of Patok Bay from the water: already worth the crossing.
First activity after arrival: guided snorkeling at the reef along Patok Bay's shoreline. Equipment fits adjusted on the beach beforehand. Guides stay in the water with the group and point out highlights. Duration approximately 45–60 minutes. The morning session – before the midday sun – has the best underwater light.
Unstructured time for exploring the island's other bays. Most guests make for Kon Kae Bay for the best coral snorkeling; others prefer the calm of Siam Bay or Ter Bay. Sun loungers and small restaurants are available at several locations around the island.
Lunch is served at the Ban Raya Resort restaurant directly on the island. The menu features Thai and international dishes; the setting – looking directly onto the bay – is one of the most scenic lunch spots of any Phuket day trip. Vegetarian options available – mention at booking.
After lunch: additional snorkeling at Kon Kae Bay, or simply rest on the beach. The afternoon session at Kon Kae typically has fewer swimmers as some guests have moved on. Last chance to spot turtles before departure.
Speedboat departs Racha Island in mid-afternoon. Return crossing approximately 30–40 minutes. Minibus transfer back to your hotel. Arrival typically between 17:00 and 18:00.
One of the most frequent planning questions from Phuket: Racha Island or Phi Phi Islands? Both are excellent – but for very different types of traveller.
Our verdict: Racha Island is the stronger choice for snorkeling quality, tranquillity and genuine relaxation. Phi Phi is better for spectacular landscape photography and well-known highlights. Both can be visited on separate days – they complement each other well.
Calm sea, excellent underwater visibility and sunny weather make these months the ideal time for a Racha Island day trip.
The reef is at its most vibrant and clarity peaks in January and February. Tip for manta ray encounters: Anyone wanting to see mantas at Racha Noi should plan a diving trip between January and March – sightings are near-guaranteed during this window. High season December to March – book early.
A specific advantage Racha Island holds over most Phuket day-trip destinations: the sheltered bays of Kon Kae Bay and ...
Ter Bay often remain accessible even during the monsoon, when other islands close due to rough sea conditions. Fewer visitors and lower prices make the low season more attractive here than elsewhere. Always verify conditions at time of booking – TIP will advise directly.
