Reykjavik might be more famous for its geysers, waterfalls, and volcanic landscapes, but it also offers some of the most unique scuba diving opportunities on the planet. The clear, cold waters of Iceland’s Silfra Fissure are a standout, especially because you get to swim right between the Eurasian and North American tectonic plates. We particularly love the Silfra: Diving Between Tectonic Plates and Pick Up from Reykjavik, thanks to its small group size, personal service, and all-inclusive setup. It’s a bucket-list experience that combines geology, adventure, and pristine underwater scenery.
If you’re short on time but still want a taste of Iceland’s underwater marvels, the Dive the Divide: Silfra Fissure Scuba Tour | Meet at Thingvellir offers a half-day visit that highlights the stunning underwater caverns and clarity of the water. For seasoned divers, the Silfra: Diving Between Tectonic Plates provides a more in-depth exploration with a focus on the geological features and the chance to really get into the details of this singular location.
