Best Snorkeling Spots Near Phuket
Phuket's Snorkeling Options
The Andaman Sea surrounding Phuket is home to diverse coral reef ecosystems that support hundreds of species of tropical fish, sea turtles, reef sharks, and other marine life. The quality of snorkeling varies significantly depending on where you go. This guide ranks the best snorkeling spots accessible from Phuket, from the most spectacular to the most convenient.
Tier 1: World-Class Snorkeling
1. Similan Islands
The Similan Islands offer the best snorkeling accessible from Phuket. Period. The combination of crystal clear water (25+ meters visibility), pristine coral reefs, and abundant marine life puts the Similans in a league of their own.
What you will see: Sea turtles, reef sharks, giant clams, enormous schools of tropical fish, healthy hard and soft corals in brilliant colors. The underwater granite boulders at Island 9 create dramatic swim-throughs.
Accessibility: Day trip from Phuket (12+ hours total, November to May only). Requires early morning start and long transfers.
Best for: Anyone who prioritizes snorkeling quality above all else.
2. Surin Islands
Nearly as impressive as the Similans, the Surin Islands have even more pristine reefs in some areas due to fewer visitors. The shallow reefs are accessible to all skill levels, and the diversity of hard corals is remarkable.
What you will see: Over 200 species of hard coral, sea turtles, reef sharks, vast schools of fish, potential manta ray sightings.
Accessibility: Very long day trip from Phuket (14+ hours, November to May only). Easier from Khao Lak.

Tier 2: Excellent Snorkeling

4. Phi Phi Islands (Shark Point and Surrounding Areas)
The snorkeling around the Phi Phi Islands is varied, with some spots being excellent and others showing more reef damage from heavy tourism. Shark Point (Hin Phae) is the standout location, known for blacktip reef sharks in shallow water.
What you will see: Blacktip reef sharks, sea turtles, parrotfish, triggerfish, healthy soft corals at deeper spots.
Accessibility: Full day trip, 45 to 60 minutes by speedboat. Available year round (some cancellations in monsoon).

What you will see: Diverse reef fish, anemones with clownfish, parrotfish, sea cucumbers, occasional small sharks.
Accessibility: Usually visited as part of a Phi Phi Islands tour.

What you will see: Parrotfish, surgeonfish, groupers, healthy hard corals, occasional turtles.
Accessibility: Easier from Krabi/Ao Nang. Possible from Phuket by private speedboat (90 minutes).
7. Kata Noi Beach (Southern End)

What you will see: Small reef fish, sea urchins, occasional larger fish, modest coral coverage.
Accessibility: Walk in from the beach. Free. Best during dry season when water is calm.

Accessibility: Walk in. Free. Can be rough in monsoon season.
Tier 4: Basic Snorkeling
9. Coral Island (Koh Hae)
Coral Island has suffered some reef degradation from heavy tourist traffic, but you can still see a variety of reef fish and some coral, especially at the quieter Banana Beach on the northern end.
What you will see: Reef fish, sea urchins, some coral, occasional larger fish.
Accessibility: Very easy, 15 minutes from Phuket. Available year round.
Best for: Combining beach activities with light snorkeling. Not a dedicated snorkeling destination.
Tips for Better Snorkeling
- Bring your own mask. A well-fitting mask that does not leak or fog transforms the experience.
- Use a rash guard. It lets you snorkel longer without worrying about sunburn.
- Swim slowly. Thrashing scares fish away. Slow, calm movement brings marine life closer.
- Look under ledges and in crevices. Some of the most interesting creatures (moray eels, octopus, lobster) hide in dark spaces.
- Do not touch anything. Coral is fragile and takes years to grow. Sea urchin spines cause painful injuries. Just look, do not touch.
- Snorkel in the morning. Water is usually calmest and clearest before noon.
