Reviews: Silfra: Fissure Snorkeling Tour with Underwater Photos
Guest User2026-10-19
Very interesting activity. We are scuba divers but never wore drysuits. We enjoyed the snorkel. It was very organized and the guide was very safety conscious. I'm glad we did the first available timeslot as we didn't have to wait to get into the water for other groups and found easy parking. Friendly staff from the guide to those who checked us in and suited us up.

Reviews: Snorkeling experience at Silfra fissure in Thingvellir National Park, Iceland

It was my first time snorkeling, and I was a little scared when I saw the deep cracks. I even choked on water because of it, but the instructor was very gentle and comforted us and patiently guided us.
