Upon arrival 15 minutes before the start time, you will check in with the guides at the meeting point at Silfra. Once your group of max 6 people has been formed, your guide will give you your drysuit, warm undersuit and snorkeling equipment. Your guide will explain how to use this equipment and how to ensure that you will be warm and comfortable during your tour. You can change in our heated Changing Van and the guide will help you with putting all the gear on. We recommend wearing long underwear and thick socks. Your guide will brief you on Silfra and safety as well as information about Thingvellir national park, the tectonic plates and the continents. The briefing and gearing up takes approx 1 hour. You will walk 5 minutes to Silfra and start your 30 - 45 minute snorkeling tour of Silfra Hall, Silfra Cathedral, and Silfra Lagoon. After snorkeling in the cold water, we warm you up with hot cocoa and cookies. This is your chance to chat with your guide, ask any questions you might have and take a look at the pics taken during the tour. The service level at Dive.is is the best, there is a reason TripAdvisor chose our Snorkeling Tour the No 4 experience in the world!
