About Silfra Fissure
Silfra Fissure is a remarkable underwater ravine in the heart of Thingvellir National Park, a UNESCO World Heritage Site in Iceland. It's a popular dive site and a geological wonder that fascinates scientists and tourists alike.
Silfra Fissure is unique in its location between the North American and Eurasian tectonic plates. These plates are drifting apart, creating a rift filled with crystal-clear glacial water.
The water in Silfra originates from the Langjökull glacier, about 50 kilometers away. It journeys through an underground network of porous lava rock, serving as a natural filter. This process yields crystal-clear water with visibility often surpassing 100 meters.
This extraordinary clarity makes Silfra one of the world's premier diving and snorkeling sites. Another distinctive feature of Silfra is its constant water temperature, hovering around 2-4°C (35-39°F) year-round.
Despite the cold, divers and snorkelers flock to Silfra for a unique swimming experience in such pristine and transparent water. The fissure includes several sections, including Silfra Hall, Silfra Cathedral, and the Silfra Lagoon.
Each section offers a different underwater landscape, from deep caverns to wide spaces with gentle currents. Silfra is not only a natural wonder but also a symbol of geological processes at work.
Diving or snorkeling in Silfra Fissure is not just about the underwater adventure; it's a journey into a fissure that marks the literal boundary between two continents. It's an immersive experience that combines the thrill of exploration with the awe of witnessing Earth's dynamic nature.

Safety Protocols When Diving Silfra Fissure
Safety is paramount in diving, especially in unique and challenging environments like Silfra Fissure. The location's distinctive characteristics – such as cold water temperatures, deep underwater ravines, and the need for specialized equipment – necessitate strict adherence to safety protocols.
Here are the key safety measures and protocols for scuba diving in Silfra Fissure:
Certification and Experience Requirements
Divers must have a valid diving certification, and it's highly recommended (often required) to have experience in dry-suit diving due to the cold water conditions. This is because controlling buoyancy and managing oneself in a dry suit can differ from diving in a wet suit.
Pre-Dive Briefing
All divers should receive a comprehensive briefing before the dive. This briefing typically includes details about the dive site, expected conditions, navigation routes, safety procedures, and emergency protocols.
Age and Health Restrictions
There are generally age limits (often 16 years or older) and health requirements. Divers must be physically healthy and may need to complete a medical questionnaire or provide a medical certificate.
Equipment Check
Properly functioning, high-quality dive gear suited for cold water conditions is essential. It includes a dry suit, regulators that can operate in cold water, a buoyancy control device (BCD), weights, fins, a mask, and often a hood and gloves.
A thorough equipment check before entering the water is a must.
No Solo Diving
Solo diving is generally prohibited in Silfra for safety reasons.
Buddy System
Diving in pairs or groups, where divers keep an eye on each other, is crucial. The buddy system ensures that assistance is readily available if any diver encounters difficulties.
Communication
Clear pre-dive communication about hand signals and underwater communication methods is essential. It ensures that divers can effectively communicate with their buddy and guide, especially when visibility is reduced.
Environmental Awareness
Divers should be briefed about the environmental aspects of Silfra, including the importance of not disturbing the delicate underwater flora and avoiding contact with the sides and bottom of the fissure.
Physical Fitness
Divers should be in good physical health. The cold water and the demands of diving in a dry suit require a reasonable fitness level.
Respect Dive Limits
Divers should adhere to the depth and time limits specified for the dive, considering their certification level and diving conditions.
Exposure Protection
Given the near-freezing water temperatures, appropriate exposure protection is necessary. It includes wearing suitable thermal layers beneath the dry suit.
Emergency Procedures
Knowledge of emergency procedures, including managing hypothermia, equipment malfunctions, and ascending safely in an emergency, is critical.
No Alcohol or Drugs
Divers must not be under the influence of alcohol or drugs while diving.
Local Regulations and Conservation Rules
Abiding by local regulations and understanding the conservation rules of Thingvellir National Park is essential to ensure the protection of this unique site. Interacting with or feeding wildlife is prohibited, as is touching or removing natural features.
Guided Tours
Guided tours with experienced dive Silfra guides familiar with Silfra's unique environment are especially recommended for those less familiar with diving in such conditions.
By following these safety protocols, divers can ensure a safe and enjoyable experience while exploring the underwater marvels of Silfra Fissure.
