When planning your snorkeling trip in Krabi, it’s a good idea to find organized tours or hire local guides who can take you to the best snorkeling spots. They can also provide snorkeling equipment and share valuable information about the marine life you’ll encounter.

You may not think of snorkeling as a dangerous activity but some people have heart attacks, and some are carried by currents and miss the boat back! Please be careful. Here is some more advice about staying safe while snorkeling in Krabi.

Snorkeling Cautions

Longtail and speedboats anchoring for snorkelers to enjoy snorkeling at a limestone karst rising out of the water.
Longtail boats and speedboats anchor for people to snorkel around Krabi’s islands.

Go with a known snorkeling service that uses visible floats when snorkelers are in the water. Nothing like a boat running over someone who doesn’t know there are people snorkeling in the water.

Currents can be strong during tides and other times of the year due to weather patterns. Again, going with a known outfit will help decrease the risk that currents present.

Count the people on your boat when you are heading out to the snorkeling location. Count them on your way back. It doesn’t happen often, but occasionally someone is left out there and though the water is warm, it’s a horrible situation!

Don’t step on coral or rocks, the sea anemones can pierce your foot, even through some diving shoes.

Don’t stick your hand in or near holes. We met a man who had a toe for a thumb replacement as he lost his thumb to a big moray eel after sticking it into a hole.

Though you probably won’t have any problem, I would advise not to go out on a longtail boat (any boat) when it is only girls. I mean, 1 girl, 2 girls, maybe even 3 girls. The boating industry, the tourist industry, seems to attract unskilled Thais that can’t seem to help themselves and attacks on tourists have happened.

Don’t drink alcohol on your snorkel trips! Should go without saying, right?

Dangerous Marine Life

Though Sea Anemones are not going to kill you, they hurt a lot and can get infected. Our landlord from Canada came to Pattaya, snorkeled, stepped on one and had spines embedded in his foot. It got infected.

Box Jellyfish and other Jellyfish. These are common in Krabi, Trang, Ko Samui, Ko Phangan, Ko Tao, Phuket, and areas on the side of the coast facing the Andaman Ocean. Be very aware if you see jellyfish in the water to avoid them if possible (if low numbers) and to get out if there are too many. Box Jellyfish have caused fatalities in Thailand, and the pain is excruciating.

Eels. We’ve already mentioned. Eels don’t typically attack anyone unless your hand is reaching for them, or into a hole, or something like that. Your fingers do look like a meal – remember!

Sharks. Sharks are not really a problem in Thailand for the most part. If you step on one or tease one, sure, you might get a bite. Otherwise, they stay to themselves and aren’t much interested in you. We don’t tend to have the aggressive sharks here like hammerheads, tiger sharks, bull sharks, or some of the other species.

Where to Buy Snorkeling Gear – Mask, Fins, Snorkel in Krabi?

Some of the dive shops in Ao Nang have snorkeling gear you can purchase before you go snorkeling.

We’d recommend you either bring your own snorkeling gear or buy it at Tesco Lotus’ near the Krabi Airport where you can find a small selection of gear in the SUPERSPORTS store. They have swimsuits, fins, snorkels, masks, and dry bags that you can choose from. The prices here are better than at the dive shops, but the gear is probably not the same quality you’d find at a good dive shop.

Where Can You Find a Snorkeling Tour in Krabi?

You can make a reservation with just about any travel agency in Krabi Town or Ao Nang. They’ll arrange a pick up for you to get you to the location and back as well. You can probably find a half-day of snorkeling for less than 2,000 THB including transportation, face-mask, snorkel, and fins.

PRO TIP! If you really want to ensure that you enjoy your snorkeling adventure in Krabi, bring your own gear from home. Really. The gear rented out here by snorkeling tour groups has been used by hundreds of people, maybe thousands. Bring your own better gear and your experience will be even better!
