Reykjavík: Snorkel Silfra Fissure in Þingvellir – Wetsuit or Drysuit

Silfra is a freshwater fissure in Þingvellir National Park, a UNESCO World Heritage Site roughly 50 km from Reykjavík. The water here is so extraordinarily clear that visibility stretches almost end to end through the fissure — snorkelers often describe the sensation as flying weightlessly through liquid glass.

The fissure reaches depths of 60–63 metres, and the glacially filtered water is among the purest on Earth. You will snorkel directly between the North American and Eurasian tectonic plates, making this one of the most geologically remarkable snorkelling experiences available anywhere in the world.

Two suit options are available: a drysuit, which uses insulating layers to keep you dry and protected from the cold, or a wetsuit, which allows you to dive beneath the surface and explore the fissure more dynamically. No diving experience or licence is required for either option.

The tour departs from downtown Reykjavík with hotel pickup included. Your guide speaks English, all snorkelling gear is provided, and free underwater photos of your experience in Silfra are included. The tour concludes with hot chocolate before the return transfer to Reykjavík.

Your guide will collect you from your downtown Reykjavík hotel before the tour begins. The transfer to Þingvellir National Park takes approximately 45–50 minutes, giving you time to take in the Icelandic landscape en route.

On arrival at the Silfra car park, your guide will brief the group and help everyone suit up. You will spend approximately 30–40 minutes snorkelling in the fissure itself, drifting through passages of exceptional clarity between the tectonic plates.

• Choose wetsuit snorkelling to dive beneath the surface, or drysuit for a more buoyant, surface-level experience
• English-speaking guide accompanies the group throughout
• Free underwater photos are taken during the snorkel
• Hot chocolate is served after the snorkel
• Return transfer drops you back in downtown Reykjavík

Total tour duration, including pickup, transfer, briefing, suiting up, and snorkelling, is approximately 4 hours 30 minutes.

This tour is operated by Adventure Vikings, the only Icelandic company offering wetsuit snorkelling in Silfra. The wetsuit option lets you actively dive into the fissure rather than simply floating on the surface — a fundamentally different and more immersive experience.

All necessary gear is included, no prior snorkelling or diving experience is needed, and the small-group format ensures personal attention from your English-speaking guide. Free underwater photos mean you leave with a lasting record of one of Iceland's most extraordinary natural encounters, without any additional cost.
