This Silfra snorkeling tour by DIVE.IS combines rare geology with professional guidance and careful planning. Swimming between two continental plates is already extraordinary, but doing so in some of the clearest water on Earth makes the experience unforgettable.
You are guided throughout by PADI-certified instructors who focus on safety, clear instruction, and comfort in cold conditions. Groups are limited to six participants, allowing for a calm pace and personal attention.
All essential equipment is included, along with access to a heated changing van, making preparation and recovery far more comfortable. After the snorkel, warm up with hot chocolate and Icelandic cookies by the Silfra car park while learning more about the site’s unique geology.
