What is silfra snorkeling and where exactly does it take place?
Silfra snorkeling takes place inside the Silfra fissure, a water-filled tectonic crack in Thingvellir National Park (address: Silfra, Thingvellir National Park, 801 Thingvellir, Iceland) where the North American and Eurasian plates slowly drift apart. The glacially filtered water maintains year-round visibility of up to 100–120 metres, making it one of the clearest dive sites on Earth.
What are the opening hours for silfra snorkeling?
The Silfra fissure and Thingvellir National Park are open every day of the year from 00:00 to 23:59 — there is no closing time. Guided snorkeling tours operate on scheduled departure times set by individual operators, typically starting from 07:45 in summer (May 15–August 31) or 08:30 in winter (September 1–May 14).
How much does silfra snorkeling cost and what does the fee cover?
A water-entry fee of 1,500 ISK per person is charged by Thingvellir National Park for anyone entering the water at Silfra; most tour operators include this in their booking price, so verify at checkout. Parking at the park's P5 lot costs around 1,000 ISK per vehicle per day, payable via the CheckIt system, and is separate from the entry fee.
What is the best time of day to go snorkeling in Silfra to avoid crowds?
Arriving at Silfra between 08:00 and 10:00 is the recommended window to beat peak Golden Circle tour-bus crowds and benefit from morning light filtering into the fissure. Midday and early afternoon slots tend to be busiest during summer.
Do I need to be an experienced swimmer to join a Silfra snorkeling tour?
Participants must be comfortable in the water and able to swim; no prior snorkeling or diving certification is required for guided snorkel tours. You cannot join if you are pregnant, and those with serious heart, respiratory, or neck conditions should consult a doctor before booking. The minimum age on most Silfra snorkeling tours is 12 years old.
What should I wear for a snorkeling tour in Silfra?
All necessary equipment is provided by the tour operator: a thermal undersuit, a sealed drysuit, neoprene hood and gloves, fins, mask, and snorkel. Wear thin, moisture-wicking base layers and two pairs of warm socks underneath; bulky jeans or thick cotton are not suitable. The drysuit seals tightly at the neck, so guests with claustrophobia or neck sensitivities should consider this before booking.
Can children participate in silfra snorkeling?
Children aged 12 and over may join silfra snorkeling tours with a signed parental consent form. Participants must fit into the available drysuit sizes and be confident swimmers; tour operators assess suitability on the day. Children under 12 are not permitted in the water but can enjoy the park's trails and boardwalks nearby.
Is photography allowed during the Silfra snorkeling experience?
Bringing a personal waterproof camera or underwater housing into the fissure is allowed and encouraged. Most tour operators carry a GoPro throughout the tour and offer the guide-taken photos to participants afterward — sometimes complimentary, sometimes for an additional fee around 3,000 ISK. Avoid obstructing other snorkelers with large camera rigs at narrow sections of the fissure.
What is the cancellation policy for silfra snorkeling tickets?
Most operators offer a full refund when a silfra snorkeling tour is cancelled at least 24 hours before the scheduled start time in Icelandic local time (GMT). Cancellations within 24 hours of departure are generally non-refundable, and the 1,500 ISK water-entry fee paid to Thingvellir National Park is non-refundable once used.
Are there food and drink facilities at Silfra?
There is no food or drink vendor at the Silfra fissure itself. Most guided snorkeling tours include hot chocolate and biscuits served immediately after the in-water session. A café and restaurant operate at the Thingvellir National Park Visitor Centre at Hakid, approximately 3.5 km from Silfra.
How do I get to Silfra from Reykjavik?
Silfra is about 50 km northeast of Reykjavik along Route 36, a drive of roughly 45–60 minutes. Self-drivers park at the P5 (Valhöll) lot and walk 5 minutes to the Silfra meeting point; most tour operators also offer minibus transfers from Reykjavik pick-up points, departing from around 07:45 in summer. There are no trains in Iceland.
What other attractions can I combine with a Silfra fissure snorkeling visit?
After your snorkel in the Silfra fissure, the Almannagja Gorge boardwalk and Oxararfoss Waterfall are a short 10–12 minute drive from P5 and make natural additions to the same day. The Hakid Viewpoint at the Visitor Centre overlooks Thingvallavatn Lake, Iceland's largest natural lake, and the Law Rock (Logberg) historic parliament site is also reachable on foot from the same car park.
