The 5 best Snorkeling Safety Tips on Koh Tao

Tip 1. Let someone know your plans

If travelling alone and you plan to snorkel alone, always let someone know where you are going and what you are planning to do. Even better, go snorkeling with a buddy or as a group whilst making new friends.

If you are on an organised snorkel trip on Koh Tao listen to the safety briefings by expert and knowledgeable snorkel guides and stay within a safe distance from the boat.

Plan Your day

Koh Tao has dozens of beaches and bays that are all within reach of your accommodation. However, some of the beaches on Koh Tao are difficult to access as it involves a hike through the mountainous jungle and inevitably across private land.

It is always best to check with local guides or a tourist information office who know the local weather patterns, tides and if there are any special conditions in place for a particular location. Be sensible and do the right thing.

Wear a Life jacket

Tip 2. Wear a life jacket

Life jackets may seem cumbersome but its job is to keep you afloat. Swimming or snorkeling in water that is too deep to stand in, is strenuous and tiring both physically and mentally, even in calm conditions.

Keeping a life jacket with you is even more important if you are snorkeling alone or near any of the bay headlands around Koh Tao’s peninsulas.

Wind and current can change direction and it is essential you have a buoyancy device with you at all times.

Regardless if you are a strong swimmer, a life jacket will give you time to rest and recover should you experience incapacitating leg cramps or sudden fatigue.

All Koh Tao Snorkel trip operators provide life jackets for your safety, so you can focus on enjoying your day and experiencing the amazing underwater world from the surface.

Amazing Place

Tip 3. Do not Touch, Feed or Chase any Marine Life

When snorkeling on Koh Tao, you are entering a whole new world and the natural, wild habitat of marine life.

The underwater world is an amazing place and Koh Tao offers visitors a view of living coral reefs that have evolved over millennia.

It is important not to touch and contaminate coral with any part of your body and similarly, it is very important not to feed fish an unnatural diet of processed food designed for human consumption. *Green Fins

Do Not Touch

This sort of behaviour is detrimental and damaging to the very living organisms and species that you have come to see. Please do not be tempted to do it.

Ahoy! a Whaleshark, Sea Turtle or a baby Black Tip Reef Shark is high on every visitors checklist and is super exciting to witness.

In all the excitement it is easy to forget where you are and you could be tempted to reach out and touch or follow these types of passing marine life.

For your own safety, it is best to look from a safe distance and enjoy the experience while it lasts.

Tip 4. Stay Hydrated

Koh Tao enjoys hot sunshine during the day and can leave you feeling dehydrated very quickly, which can lead to other problems such as fatigue and cramp if you are swimming or snorkeling in the open sea.

Stay Hydrated

If you are exploring a remote beach or bay alone whilst snorkeling, please ensure you take an adequate supply of fresh drinking water (preferably in a re-usable drinking bottle).

If you are enjoying one of Koh Tao’s famous snorkeling trips on an organised snorkel boat, you will find an abundance of fresh drinking water and snacks to ensure you do not become dehydrated.

You may not be aware of the symptoms of dehydration and they can escalate quickly, leading to additional problems for you whilst you are snorkeling in deep water.

Eco Friendly

Tip 5. Use Eco Friendly Sunscreen

It is common knowledge that the regular sunscreens available over the counter at many shops have contaminants in them that harm everything in the sea.

They contain harmful ingredients that will rapidly destroy marine life that has evolved over thousands of years.

Waterproof does not mean it does not wash off in the abrasive salt water environment. Please consider helping the environment and wear only ‘Eco-friendly Sunscreens’.

It is essential when snorkeling that you apply an ‘eco friendly sunscreen, as your skin will burn.

Protect Yourself

An even better solution is to wear a piece of clothing to cover your back and try to protect your neck and head from the suns UV rays.

Koh Tao gets extremely hot during the day and the UV rays from the sun are amplified in shallow water.

While you will feel cool and comfortable in the water during your activity, by the evening your skin will start to become very hot, prickly and blister.
