Silfra is one of the world's most dramatic snorkeling sites. It's a glacier meltwater-filled rift formed by the drift of the Eurasian and North American tectonic plates. This tour makes snorkeling the rift as easy as possible by including a guide, dry suit and snorkeling equipment, and Silfra entrance fees. After you've snorkeled, you're offered hot chocolate and cookies. Please note that participants who are 60 years of age and older must have their doctor sign the approval form in order to participate.
