Discover the thrill of snorkeling in Iceland’s Silfra fissure with guided tours, included photos, and all gear provided—perfect for adventure seekers.
If you’re heading to Iceland and craving a truly unique adventure, snorkeling in the Silfra fissure should be at the top of your list. This experience combines breathtaking scenery, geological wonder, and the thrill of floating between two continents — all in the crystal-clear waters of Thingvellir National Park. While I haven’t personally taken this tour, reviews and detailed descriptions paint a vivid picture of what you can expect.
One of the standout features of this tour is the expert guidance and all-inclusive setup, making it accessible even for those new to snorkeling or unfamiliar with cold water adventures. The chance to see underwater visibility of about 100 meters in glacier-fed water is captivating. However, it’s worth noting that this activity requires some preparation and adherence to medical and safety requirements, especially for those with certain health conditions.
This tour is tailor-made for adventure lovers who want a safe, guided experience with easy transportation from Reykjavik. If you’re comfortable in water and eager to explore one of Iceland’s most iconic natural features, this experience offers fantastic value — especially with free underwater photos included. If you’re looking for a relaxed, leisurely day, though, this might not be the best fit due to the physical demands and gear constraints.

One of the first highlights is the pick-up service in Reykjavik. The minibus, marked with the Troll Expeditions logo, starts collecting guests at the specified time, with pickups potentially taking up to 30 minutes depending on your location. This flexible approach minimizes stress, especially after a long flight or busy day. The journey to Thingvellir National Park is smooth and scenic, giving you a glimpse of Iceland’s diverse landscape even before the main event.
The transport is equipped with WiFi, which is a nice touch if you want to share your trip in real-time or catch up on some emails during the drive. The small group size ensures personalized attention and makes for a more relaxed and social atmosphere.
Once you arrive at the famous Silfra fissure, you’re greeted by an unassuming lake from the outside. It’s easy to mistake it for a regular spot, but wait until you’re underwater. The fissure lies between North American and Eurasian continental plates, making it a geological marvel. The walk to the water takes about five minutes, during which guides will prepare you for the gear and safety instructions.

The tour includes all necessary snorkelling equipment, including a dry suit and under-suit designed to keep you warm and dry. Reviewers like Lyndsey and Tülay appreciated the professionalism of guides Gerys and Vero, who made them feel safe and comfortable. The dry suits fit snugly, especially around the neck, which might feel tight but is essential for warmth in sub-zero waters.
You’ll want to wear comfortable clothes underneath — thermal layers are highly recommended. The guides will adjust your gear and give clear instructions, ensuring you’re ready for the water. The team’s professionalism is praised repeatedly, with Lilian and Vero going above and beyond to take photos of everyone underwater.

The water here is incredibly clear, thanks to the glacier melt feeding into the fissure. Visibility can reach about 100 meters — an astonishing sight that makes you feel like you’re floating through an underwater crystal cathedral. Reviewers noted that the experience of swimming between the tectonic plates, with only a thin layer of water separating them, is both surreal and awe-inspiring.
Expect to spend approximately 30-40 minutes in the water, with guides showing you the best spots and ensuring your safety. The underwater photos are a big hit with travelers, capturing moments that look almost otherworldly. Many reviewers like Noah and Lyndsey rave about their photos and the professional service.

Once out of the water, enjoy some warm hot chocolate or tea, along with Icelandic chocolate bars. This small gesture helps everyone warm up after their chilly swim. The guides are friendly and engaging, sharing insights about the park and the geological significance of the fissure.

After all the excitement, the ride back to Reykjavik is smooth and relaxed. Some trips end with a chance to review photos or chat about the experience, making it a well-rounded outing. The entire tour lasts around six hours, making it a substantial but manageable day trip.
At $192 per person, this tour offers excellent value considering everything included: transport, snorkelling gear, dry suit, photos, and post-activity treats. The small-group format ensures you’re not lost in a crowd and allows guides to give personalized attention. The inclusion of free underwater photos is particularly appealing, as most travelers want to relive this extraordinary experience without the hassle of taking their own pictures.
While the price seems reasonable given the level of professionalism and equipment provided, it’s not suited for everyone. The activity requires basic swimming skills, and participants must meet certain health criteria, including age restrictions (12-69 years old). Individuals with back, heart, or other serious medical conditions are advised against taking part.
The tour’s flexible booking policy — free cancellation up to 24 hours beforehand — makes it easier for travelers to commit without worry. Payment is deferred until after booking, which adds a layer of convenience.
This experience is ideal for adventure seekers who enjoy water activities and want a safe, guided introduction to snorkeling in a truly iconic location. It suits those who appreciate geological marvels and are eager to explore Iceland’s natural beauty from a different perspective. It’s a fantastic choice for travelers staying in Reykjavik who want a full-day experience without the hassle of organizing transportation or gear.
However, it’s less suitable for families with children under 12, elderly travelers over 70, or those with significant medical issues. If you’re not comfortable in water, or if you prefer a more leisurely, land-based tour, this might not be the best fit.
Snorkeling in Silfra from Reykjavik offers a rare glimpse into Iceland’s geological landscape and an adventure that’s both safe and exhilarating. The professionalism of guides like Vero and Lilian, combined with the stunning clarity of the water, makes for a memorable experience. Plus, the inclusion of underwater photos means you’ll have keepsakes to cherish long after you leave.
This tour strikes a wonderful balance of excitement, safety, and value, making it a top choice for those wanting to tick an incredible activity off their Iceland bucket list.
