Experience stunning underwater clarity in Silfra with a guided freedive from Thingvellir. Small-group tour includes gear, warm clothing, and hot chocolate for $219.
A guided Silfra Freedive Adventure from Thingvellir offers a unique chance to explore Iceland’s clearest waters while floating between two tectonic plates. Priced at $219 per person and lasting approximately 3 hours, this tour delivers an intimate experience with a small group limit of 6 participants. The tour leads you into the Silfra fissure, renowned for its over 100 meters of visibility, and includes all necessary diving gear, a wetsuit, and dryrobe overcoats to keep you warm.
What makes this experience stand out is the chance to freedive in the ravines that lie right between North America and Europe, an extraordinary setting for underwater adventures. The tour is guided by a bilingual expert, ensuring safety and personalized attention. After your swim, a hot chocolate provides a cozy finish to this memorable outing. While not suitable for children under 12 or those with certain health conditions, this activity appeals especially to those comfortable in the water and eager for a more immersive alternative to snorkeling.


The Silfra fissure is a geological marvel, formed where the North American and Eurasian tectonic plates drift apart. Guided by expert guides, visitors enter water channels nestled between these plates, experiencing a place where land and sea meet beneath the surface. The tour begins at the Þingvellir National Park, with participants parking at the Thingvellir P5 lot and walking about 300 meters to the meeting point where all dive vans are parked, marked with the Freedive Iceland logo.
Once at the starting point, guests gear up in 7mm open-cell wetsuits and dryrobe overcoats, leaving all belongings in the van-changer. The guide provides safety instructions, explaining the route and what to expect during the freedive. This setup ensures a smooth start, with enough time to get ready and acclimate before entering the water. The small group size enhances the experience, making it feel private even during busy days at Silfra.
Despite the water temperature being cold, the wetsuits keep participants comfortable throughout the approximately 3-hour tour. The 7mm wetsuit is designed for dry land and water, providing insulation so you can focus on enjoying the underwater spectacle. The dryrobe overcoats are available to dry off and warm up between dives or once out of the water, ensuring that comfort is maintained during the brief rest periods.
Gear such as fins, masks, and snorkels are included and suited for freediving, though reviews suggest that using the longer freediving flippers might enhance the experience further. The guide makes sure everyone’s equipment fits well and operates smoothly, especially important given the variety of heights and sizes in small groups.

Once everyone is suited up, the group heads to the staircase leading into the water. Freedivers then duck-dive into Silfra’s fissure at their own pace, swimming through narrow ravines and along the cracks between the tectonic plates. The guides stay close, offering support, safety tips, and explanations about the geological features.
The water clarity is exceptional, with over 100 meters of visibility creating an almost surreal experience. Freedivers can swim freely and comfortably, enjoying the mild current that helps with navigation and adds a sense of gentle motion. The duration in the water is flexible, allowing participants to stay as long as they wish to soak in the peaceful, pristine environment.
This tour’s limit of six participants creates a more personalized and relaxed atmosphere. Unlike larger groups, this allows the guide to give more individual attention, answer questions, and ensure everyone feels comfortable. This small size is especially appreciated by those new to freediving, as guides can tailor their guidance to different experience levels.
Guests consistently praise the helpfulness and knowledge of the guides, like Biggie and Bjarney, who ensure safety while keeping the mood light and fun. Clear communication and attentive support contribute to the positive reviews, with many describing the experience as intimate and highly memorable.

After emerging from the crystal-clear waters, guests return to the changing van to dry off and relax. The hot chocolate served at the end offers a comforting way to warm up after the cool water experience. This simple but appreciated gesture enhances the overall comfort and satisfaction of the tour.
The return to the meeting point is straightforward, with no additional transportation required. Participants can then continue with their Iceland adventures or explore nearby attractions at their own pace.
