Reykjavík: Snorkeling in Silfra Fissure – Wetsuit & Drysuit Options

Silfra is ranked among the world's premier dive and snorkel sites, tucked inside the Þingvellir National Park UNESCO World Heritage Site, roughly 50 km from Reykjavík. This extraordinary freshwater fissure reaches depths of 60–63 metres, and its glacially filtered water is so clear you can see almost from end to end — an experience guides often describe as feeling like flying.

This 2-hour 30-minute snorkeling tour is operated by Adventure Vikings, the only Icelandic company offering wetsuit snorkeling in Silfra. While a drysuit provides thermal insulation by trapping layers of air, the wetsuit option lets you actively dive into the fissure rather than simply floating on the surface — making for a far more immersive and dynamic experience.

No diving experience or diving licence is required. Your English-speaking guide will brief you fully on site, help you suit up, and lead you through the fissure at a comfortable pace. All necessary snorkeling gear is provided, and complimentary photos are included so you can focus entirely on the experience.

After your snorkel, warm up with a cup of hot chocolate while your guide wraps up the session. The actual time spent snorkeling in Silfra is approximately 30–40 minutes, with the remainder of the tour covering briefing, suiting up, and post-snorkel wind-down.

Your tour begins at the Silfra car park in Þingvellir National Park. Park at the Þingvellir P5 parking lot and walk approximately 400 metres back along the road to the snorkel and dive van area, where your Adventure Vikings guide will be waiting. Arrive at the meeting point at least 15 minutes before your tour is scheduled to begin.

After check-in, your guide will deliver a full safety briefing and help you into either a drysuit or wetsuit. The wetsuit is the recommended choice — it allows you to dive beneath the surface and explore the fissure more actively, rather than floating on top as you would in a drysuit.

• Approximately 30–40 minutes of active snorkeling inside the fissure
• Exceptional underwater visibility in glacially filtered freshwater
• Guided experience with complimentary photos taken during the snorkel
• Hot chocolate served after the snorkel to help you warm up

Total tour duration, including briefing and suiting up, is 2 hours 30 minutes.

Adventure Vikings is the only operator in Iceland offering wetsuit snorkeling in Silfra — a meaningful distinction. The wetsuit allows active diving into the fissure, delivering a far more engaging experience than the passive float a drysuit provides.

The tour is compact at 2 hours 30 minutes, making it easy to combine with other activities in the Þingvellir area. Gear, a knowledgeable English-speaking guide, complimentary photos, and hot chocolate are all included — no separate equipment hire needed.

With no diving licence or prior experience required, this tour is accessible to any confident swimmer who meets the physical prerequisites, making it one of Iceland's most approachable bucket-list water experiences.
