Snorkel between tectonic plates in Iceland's Silfra fissure with dry suits, guided by certified instructors. Enjoy stunning underwater views and free photos.
Snorkeling in Silfra, Iceland’s famous fissure located within UNESCO’s Thingvellir National Park, offers something truly extraordinary: the chance to float between two continents in crystal-clear waters. This tour promises an unforgettable experience, combining natural wonder, expert guidance, and a bit of adventure gear. From dry suits that keep you warm to the breathtaking views underwater, it’s a trip that’s often praised for its authenticity and value.
What we love most? The expert guides, like Niko and Klaudyna, who make sure every participant feels safe, comfortable, and informed, even if it’s your first time in water. Plus, the included underwater photos let you relive the moment without scrambling for your camera.
A potential consideration? The dry suits can feel quite tight and constricting, especially around the neck and wrists, which might be uncomfortable for some. Also, the tour lasts around 3 hours, but most of that is geared towards gearing up, briefing, and changing, with about 40 minutes in the water — so be prepared for a quick but impactful experience.
This tour suits travelers who are comfortable swimming, want to explore something genuinely different, and aren’t put off by cold water or tight-fitting suits. It’s particularly great for those celebrating special occasions or looking for a bucket-list adventure in Iceland.


The adventure kicks off at the meeting point in Thingvellir National Park, about 50 km from Reykjavik. Arriving here, you’ll be greeted by your guide and quickly checked in. Most reviews mention how well-organized and warm the changing facilities are—crucial for the cold Icelandic weather. Klaudyna, one of the guides, is often praised for her professionalism and attention to detail, making participants feel at ease right from the start.
Once suited up in your dry suit—an experience some find a bit tight but usually very effective—you’ll head toward the snorkel entry point. The process of putting on the gear, checking the fit, and listening to safety instructions takes around 15 minutes. The guide will review safety protocols, including how to communicate underwater, which is key since the water is so clear that visibility extends beyond 100 meters.
The actual snorkeling involves navigating through an underwater canyon or fissure formed as the tectonic plates drift apart at about 2 cm per year. Here, you’ll glide through the water, marveling at the spectacular colors and clarity that make Silfra one of the top snorkeling spots globally. Reviewers consistently mention the surreal feeling of “flying” through the water or the sensation of being in a different world. A common comment is how the water, despite being around 2°C, feels almost warm thanks to the dry suits, which are designed to keep you dry and insulated.
Expect to spend approximately 40 minutes in the water, with most participants describing the experience as both peaceful and exhilarating. Some reviewers highlight the importance of wearing thermal layers underneath, such as long underwear and wool socks, which greatly enhance comfort. The guides often take plenty of photos, capturing moments that you’ll treasure long after the tour ends.
After snorkeling, you’ll walk back to the changing area, where your dry suit is removed, and you’re handed a warm hot chocolate—an appreciated touch to warm up after the chilly dip. Many reviewers note that the hot chocolate, served by guides like Ed, is the perfect end to an already memorable experience.

The process begins with a thorough briefing where guides explain safety measures and what to expect. Expect a short walk on a platform before slipping into your gear, which some describe as feeling quite snug but reassuringly secure. As Jennifer H notes, “your suit leaked a bit from the back when I turned over, but as long as I stayed face down, I was fine.” This honesty from reviewers highlights that minor discomforts are common but manageable.
Once in the water, you’ll notice how remarkably transparent the water is—seeing the bottom at 100 meters is possible. This clarity, combined with the silence and stillness underwater, creates a sensation of floating in a different realm. Many reviewers mention how relaxing and peaceful the experience is, even if your hands or feet go numb at times. The guides are attentive and will help if anyone feels uncomfortable.
It’s worth noting that the guides also take plenty of photos, often capturing your face underwater with a big smile, and some reviews mention how those pictures become treasured keepsakes. The hot chocolate served afterward is a simple but appreciated reward, especially considering the chilly water temperature.

Several reviews highlight the professionalism of guides like Arnold, Hugo, Ed, and Klaudyna. Their expertise clearly reassures nervous participants and ensures safety is always a top priority. For example, as one reviewer states, “Ed was fantastic and gave us lots of good information and support.” Their friendly, patient approach makes the whole experience approachable for first-timers and seasoned swimmers alike.
Guides also help with gear fitting, ensuring dry suits or wetsuits are correct size and properly sealed. Klaudyna, in particular, gets praise for her confidence and ability to put everyone at ease, as well as her attention to safety details—crucial when dealing with cold water and tight-fitting suits.
