Snorkeling in Krabi

Krabi is home to some of the clearest waters and healthiest coral reefs in southern Thailand. Snorkeling here is easy — even for beginners — with shallow spots close to the islands and warm sea conditions almost all year round. The mix of colorful marine life, limestone scenery, and easy access from the mainland makes snorkeling one of the top things to do in Krabi.

Krabi has plenty of snorkeling spots, but these are some of the best if you're looking for clear water and colorful reef life:

• Chicken Island: Easy access and lots of shallow coral — a favorite for beginners and families.
  
  
• Ko Ya Wa Sam: Small and quiet, with calm waters and plenty of tropical fish. Great visibility on good weather days.
  
  
• Ko Ma Tang Ming: A lesser-known spot with untouched reef and a peaceful setting. Perfect if you want fewer crowds.
  
  
• Ko Raeng: Rocky islets just off the coast with deeper water and bigger fish — best for confident swimmers.
  
  
• Daeng Island: Known for its bright coral and clear water. Often part of Hong Island routes.
  
  

Most of these are visited by longtail or speedboat on island tours. Your guide will usually pick the best snorkeling spot depending on tides and sea conditions.

Snorkeling in Krabi is simple, relaxing, and full of surprises. Here’s what a typical experience looks like:

• You’ll start with a short boat ride to one of the nearby islands.
• The guide will give a quick briefing and hand out your gear (mask, snorkel, and life jacket if needed).
• Once you're in the water, just float and watch the fish! You might see clownfish, parrotfish, sea urchins, and colorful corals.
• Each snorkeling stop usually lasts 30–45 minutes, with time to rest or explore the beach in between.
• Most tours visit 2–3 spots, so you’ll get a mix of reef types and underwater scenery.
• It’s peaceful, beginner-friendly, and one of the easiest ways to connect with the natural side of Krabi.

Snorkeling in Krabi is safe and beginner-friendly, especially when done with local guides who know the tides and reef conditions.

Here’s what’s usually provided:

• Snorkel gear: Mask, snorkel, and life jackets included in all tours
• Life jackets: Optional but available for comfort and safety — great for kids or non-swimmers
• Basic safety briefing: Quick overview before jumping in — how to use the gear and stay safe around coral
• Experienced guides: Keep an eye on the group, suggest good spots, and help first-timers feel confident

A few safety tips:

• Avoid touching or standing on coral — it’s fragile and sharp
• Always stay within sight of your boat or guide
• If the sea gets rough, don’t worry — your guide may adjust the route for safer spots
  

You don’t need much to enjoy a day of snorkeling, but a few essentials will help you stay comfortable and ready for anything:

• Quick-dry shirt or rash guard (for sun protection)
• Swimwear (wear it under your clothes before the trip)
• Slip-on sandals or reef shoes
• Hat and sunglasses (for the boat ride)
• Reef-safe sunscreen
• Towel and a change of clothes
• Waterproof camera or phone case (optional, but great for fish photos)
• Refillable water bottle (stay hydrated!)

Heads up: You’ll be in and out of the water, so expect to get salty, sandy, and sun-kissed. Light colors may get stained with salt or sunscreen — dark clothes are safer.

The best time to snorkel in Krabi is during the dry season, from November to April. During these months, the sea is calm and clear, giving you the best visibility underwater.

• Morning trips usually offer calmer waters and fewer crowds.
• Afternoon tours are still great but can be windier later in the day.

The rainy season (May to October) brings rougher seas and limited visibility, so it’s less ideal for snorkeling.
