DIVE.IS

Iceland's best-known dive operator, running drysuit dives and snorkel tours in the Silfra fissure at Thingvellir, where glacial meltwater filtered through lava gives visibility beyond 100 meters between the tectonic plates. Day tours include Reykjavik pickups; diving Silfra requires drysuit certification or documented drysuit experience under national park rules, and water sits near 2-4 °C year-round.

Harga: Premium day-tour pricing by European standards, with snorkeling cheaper than diving; park fees included in most quotes. Verify drysuit prerequisites honestly before booking: they are enforced.
