Is it safe for children and the elderly?

Snorkeling is safe for people of all ages as long as they are comfortable in the water and have complete control over their mobility.

You can teach your children snorkeling even when they are as young as 5 or 6 years old. With patience and close supervision on your part, snorkeling can be a safe and truly thrilling experience for kids. There are also kid snorkel sets that are tailor made for children.
 

Can people with health conditions and pregnant women go snorkeling?

While it is generally safe for pregnant women and people with mild health conditions to snorkel close to the surface of the water, a doctor should be consulted beforehand. Diving deep should be avoided.

In most cases, not only is snorkeling safe, but it also has plenty of physical and mental health benefits that add to its appeal.

Do I need any certification in order to go snorkeling?

No. Unlike scuba divers, snorkelers do not need any certification. All you need is the right equipment and a good destination, and you can begin your snorkeling experience!

How Do I Find the Right Snorkeling Equipment?

If you are planning on snorkeling for the first time, you may want to sign up for a guided excursion or trainer who provides you with all the equipment and instructions you need. Whether you opt for this, or are keen to snorkel independently and buy your own equipment, it is important that you understand all the gear you are required to wear, and that you are able to make an informed decision when checking whether a piece of equipment is safe and suitable for your own needs.

The equipment involved in snorkeling is usually fairly simple, but selecting and using it well can maximize your enjoyment of the experience. Doing your research beforehand can increase you comfort and allow you to focus all your attention on the wonderful world underwater.
