This trip was fantastic. I had no snorkelling experience at all but our guide Fonzy (not sure if I spelt that correctly!) was so helpful throughout; he made sure we knew what to expect and supported us. The suits were tricky to put on but they did a great job keeping us dry and warm. As for the snorkelling itself, relax and let the gentle current carry you so you can take in the beautiful colours and geology. An experience I won’t forget.

We had a great time! Hjortur (or adventure Jim as we call him) was amazing! Very knowledgeable and fun guide. Highly recommend him!

Greatly curated and safe experience. Veronica was the best guide and we had a lot of fun. We were not even cold :-)

Pablo the guide was very friendly and extremely helpful and informative.
