Silfra Freediving: Discovering Free Dive Iceland 2024


Iceland, a land of unparalleled natural beauty, boasts a hidden gem that beckons adventure seekers and water enthusiasts from around the world – Silfra. This extraordinary fissure, located in Thingvellir National Park, is renowned for its crystal-clear waters and mesmerizing underwater vistas. Silfra is a place where snorkeling and freediving enthusiasts gather to explore the otherworldly beauty that lies beneath the surface. In this article, we embark on a journey into the depths of Silfra, uncovering its wonders, discussing the best spots for freediving, exploring the costs involved, delving into its impressive depth, and ultimately determining whether it’s worth experiencing this underwater marvel.

Silfra Overview

Silfra is not your typical diving or snorkeling destination. What sets it apart is its geological significance and the clarity of its waters. It’s a freshwater fissure situated in the Thingvellir National Park, a UNESCO World Heritage Site, in Iceland. Silfra is unique because it is where the North American and Eurasian tectonic plates meet, creating a natural wonder that allows you to swim or dive between continents.

The Water’s Purity

The water in Silfra is exceptionally clear and pure, offering visibility that can extend up to 100 meters (328 feet). This remarkable clarity is attributed to the water’s source – it originates from Iceland’s Langjökull Glacier, where it undergoes natural filtration as it trickles down through porous lava rock for decades before emerging in Silfra.

Challenging Conditions

Despite its breathtaking beauty, Silfra can be challenging to explore due to its frigid waters. The temperature remains consistently between 2°C and 4°C (36°F to 39°F) year-round, making it one of the coldest snorkeling and freediving sites in the world. This frigidity demands specialized drysuits and gear to ensure your safety and comfort while exploring its depths.
