Þingvellir: Private Snorkeling Tour in Silfra Fissure

Silfra is ranked among the top snorkeling and dive sites on the planet — and for good reason. Located within the Þingvellir National Park UNESCO World Heritage Site, roughly 50 km from Reykjavík, this freshwater fissure reaches depths of 60–63 metres. The water is so exceptionally clear you can see almost from one end to the other, creating a weightless, flying sensation unlike any other aquatic experience.

This is a fully private tour, meaning your group has exclusive access to your guide and the experience is tailored entirely to you. No diving experience or diving licence is required — your guide will brief you thoroughly before you enter the water.

You have the choice of snorkeling in a drysuit or a wetsuit. The drysuit provides insulation through layered fabric, keeping you dry throughout. The wetsuit option, exclusively offered by Adventure Vikings among Icelandic operators, allows you to dive beneath the surface rather than simply floating on top — a noticeably more immersive experience.

After your snorkel, warm up with hot chocolate included as part of the tour. Free underwater photos of your Silfra experience are also provided, so you can relive the moment without needing to manage a camera in the water.

Your adventure begins with a transfer to Þingvellir, where your guide will conduct a full briefing and help you suit up — this preparation phase takes approximately 2 to 2.5 hours in total, including travel time. The snorkel itself lasts around 30 to 40 minutes inside the Silfra fissure.

Once in the water, you'll drift through one of Iceland's most extraordinary natural features. The glacial meltwater filtering through porous lava rock for decades produces visibility that is virtually unmatched anywhere in the world.

• Full gear fitting and safety briefing before entering the water
• 30–40 minutes of snorkeling in Silfra's crystal-clear fissure
• Private guide throughout the entire experience
• Free underwater photos delivered after the tour
• Hot chocolate to warm up afterwards

Participants must be comfortable swimmers and meet the physical requirements listed in the booking conditions. A liability release form is signed at the start of the tour.

This private snorkeling experience in Silfra stands apart from group tours. Your guide focuses entirely on your party, the pace is set by you, and the experience feels personal rather than rushed.

Adventure Vikings is the only Icelandic operator offering wetsuit snorkeling in Silfra, giving participants the option to dive beneath the surface — something not possible in a standard drysuit. All necessary equipment is provided, free underwater photos are included, and hot chocolate awaits you at the end. No prior diving experience is needed, making this accessible to most confident swimmers aged 12 years and above.
