Silfra Fissure is a natural rift in Thingvellir National Park, where the North American and Eurasian tectonic plates slowly drift apart. Filled by glacial meltwater filtered through lava rock for decades, its water is exceptionally clear and remains 2–4°C year-round.
Unlike a typical dive site, Silfra is a calm, freshwater canyon of submerged rock walls, deep crevices, and shifting light, explored by snorkeling or dry suit diving between continents.
A narrow, dramatic channel where you slip directly between two continents. Sheer rock walls and intensely clear water create a surreal first impression.
Silfra lies within Thingvellir National Park, the historic site where Iceland’s national parliament, the Alþingi, was established in 930 AD. For nearly 800 years, chieftains gathered here each summer to debate laws, settle disputes, and shape the nation.
The fissure as we know it today was created after a series of powerful earthquakes in 1789 widened existing cracks in the lava field. These seismic events opened deep fractures between the tectonic plates, allowing glacial meltwater to fill the newly formed canyon.
It wasn’t until the late 20th century that divers began exploring the fissure, drawn by reports of extraordinary water clarity. Word spread quickly within the diving community, and Silfra gained international attention as a rare place where people could float between two continents in freshwater with visibility often exceeding 100 meters.
Today, Silfra is protected as part of Thingvellir National Park, a UNESCO World Heritage Site recognized for both its geological significance and its role in Icelandic history.
Silfra is located in Thingvellir National Park, where the North American and Eurasian plates are slowly pulling apart by roughly 2 cm per year. It is one of the few places on Earth where this continental drift is clearly visible above sea level.
The fissure formed after the major earthquake in 1789 opened cracks in the surrounding lava field. These fractures are filled with glacial meltwater, creating a deep, narrow canyon of submerged rock walls and boulder chambers.
Water from the Langjökull glacier filters through underground lava rock for decades before reaching Silfra. This natural filtration results in visibility often exceeding 100 meters, with water temperatures staying between 2–4°C year-round.
Silfra is a freshwater rift formed between the North American and Eurasian tectonic plates. It’s famous for its exceptionally clear glacial water and the rare chance to float between two continents.
The water comes from the Langjökull glacier and filters through lava rock for 30–100 years before reaching the fissure, creating visibility that can exceed 100 meters.
Yes. Silfra lies along the Mid-Atlantic Ridge, where the North American and Eurasian plates slowly drift apart by about 2 cm per year.
Depth varies by section. The deepest point, in the “Silfra Cathedral,” reaches around 18–20 meters.
Yes, when visited with a certified guide. All snorkeling and diving tours include safety briefings and specialized dry suits.
Not for snorkeling. However, scuba diving requires an Open Water certification (or equivalent) and proof of dry suit experience.
Yes. Tours operate in all seasons, including winter. Snowy landscapes can make the experience especially striking.
Basic facilities and meeting points are available at the Silfra car park (P5), but amenities are limited compared to city attractions.
Wildlife is limited due to cold temperatures, but you may spot small Arctic char or tiny freshwater invertebrates.
Summer (June–August)
Winter (November–March)
Address: 7V3M+W2Q Thingvellir National Park, 801 Thingvellir, Iceland
Stroll the marked trails of Thingvellir National Park, where lava fields and dramatic rock walls frame the fissure. Easy to moderate terrain; allow 1–2 hours. Sturdy shoes and weather layers are recommended. Great for families or anyone who prefers a dry adventure, pair your walk with a morning snorkel for a full day out.
Float in crystal-clear glacial water between the North American and Eurasian plates inside Silfra Fissure in Thingvellir National Park. Expect 30–45 mins in 2–4°C water, wearing a drysuit, mask, fins, and thermal layers (all provided on guided tours). Intensity is moderate; you should be comfortable in water. Ideal for first-timers and bucket-list seekers, book a guided slot to secure photos and small-group support.
Explore deeper sections like the Cathedral with a licensed guide. Dives typically last 30–40 minutes and require drysuit certification (or logged drysuit dives). Water remains 2–4°C year-round; full diving gear is provided on tour. Intensity is higher than snorkeling and best for certified divers who want extended bottom time. Reserve in advance due to limited spots.
Balance the cold-water thrill with a warm lagoon visit the same day (popular pairings include oceanfront or countryside hot springs). Minimal intensity; stay as long as you like. Bring swimwear and flip-flops. It’s a relaxed, romantic finish. Choose a combo ticket to streamline logistics and save time.
