Welcome to Seal Snorkelling Adventures. This is a new business that is creating an unforgettable experience swimming with the amazing wild seals that surround our beautiful islands. We offer trips out to our eastern islands where we give you the chance to swim with Atlantic grey seals as well as having a possible close encounter. We run two trips a day which include wetsuit hire, snorkel and mask hire, boat trip, and an hours snorkelling in our lovely blue waters with the seals followed by a nice warm drink and a snack once you have finished in the water. 


The Experience

Snorkelling with seals. Watching wild seals swimming effortlessly in their natural environment is a fabulous experience. As they are wild animals they are in control of the whole experience and sometimes coming up very close and playing with your fin.

There is no snorkelling experience needed for the 2.5 hour trips but we do ask you to be comfortable swimming in open water. We have local diving instructors that will brief you and guide you in to the correct areas and will be able to assist in any way possible.

All of our trips are done in the Atlantic ocean so please be aware of the cold waters. As we know some people feel the cold so our prices include thick winter wetsuits to keep everyone warm and buoyant. 

The minimum age for snorkelling is 12 years. All children under the age of 16 must be accompanied by an adult.

We do reserve the right to cancel any trips should the sea or weather conditions make it unsuitable for snorkelling. 


Our main tips for swimming with seals:

Stay calm and quiet

Do not chase after the seals.

Do not get too close or disturb the seals hauled out on rocks
