Diving Between Continents: Unforgettable Silfra Experience Unveiled

Introduction

Iceland is a land of stunning natural beauty, with its rugged landscapes, towering mountains, and awe-inspiring glaciers. But did you know that Iceland is also home to one of the most unique diving experiences in the world? The Silfra Fissure, located in the Þingvellir National Park, offers divers the opportunity to explore the fascinating underwater world between two continents. This article will take you on a journey through the Silfra Fissure, exploring the history, geology, and the incredible diving experience it has to offer.

1. The Geology of Silfra Fissure

The Silfra Fissure is situated within the Þingvellir National Park, a UNESCO World Heritage Site in southwestern Iceland. The park is renowned for its geological and historical significance. The fissure itself is a crack formed between the North American and Eurasian tectonic plates, which are slowly moving apart. This movement has created a unique underwater canyon system filled with crystal clear glacial meltwater.

As the fissure widens, water from the nearby Langjökull glacier makes its way into the underground lava fields, slowly filtering through the porous volcanic rock. This process can take up to 30 years, resulting in some of the clearest water on Earth. The water in Silfra is so pure that it exceeds the quality of most drinking water. The clarity of the water is a result of the slow filtration process, which removes any impurities, leaving behind only pure, fresh, and cold water.

Due to the slow flow of water through the porous rock, the temperature of the water in Silfra remains a constant 2-4 degrees Celsius (35-39 degrees Fahrenheit) all year round. While this may sound chilling, it is one of the factors that make diving in Silfra such a unique and magical experience.

2. The Dive Experience

2.1. Diving Silfra: A Once-in-a-Lifetime Adventure

The Silfra Fissure offers a truly extraordinary diving experience unlike any other. Once inside the water, divers are immersed in a world of stunning underwater vistas with visibility that can reach up to 100 meters (328 feet). The incredible clarity of the water allows for breathtaking views of the underwater rock formations, crevices, and even fish that inhabit the fissure.

The dive itself is a drift dive, meaning that divers enter the water at one end of the fissure and let the current gently carry them through the various sections of the canyon. It’s an effortless dive that requires minimal finning, making it suitable for divers of all experience levels.

2.2. The Four Sections of Silfra Fissure

The Silfra Fissure is divided into four distinct sections: Silfra Hall, Silfra Cathedral, Silfra Lagoon, and Silfra Crack. Each section offers its own unique features and underwater landscapes.

2.2.1. Silfra Hall

Silfra Hall is the first section of the fissure that divers will encounter. It is the widest part of the fissure, providing divers with ample room to explore. The deep blue waters of Silfra Hall are mesmerizing, with light filtering through from above, creating an ethereal atmosphere.

2.2.2. Silfra Cathedral

As divers move deeper into the fissure, they will come across Silfra Cathedral, one of the most impressive parts of the dive. Silfra Cathedral is a narrow section of the fissure with incredibly high vertical walls, creating a sense of diving through a magnificent underwater canyon.

2.2.3. Silfra Lagoon

After passing through Silfra Cathedral, divers will enter Silfra Lagoon. This section is shallower, allowing divers to take their time and immerse themselves in the beauty of their surroundings. Silfra Lagoon is also known for its abundance of colorful algae, which adds a vibrant touch to the underwater landscape.

2.2.4. Silfra Crack

The final section of the Silfra Fissure is Silfra Crack, a narrow and challenging passage that divers must maneuver through. Silfra Crack is the most famous part of the fissure, and for good reason. Divers will feel as though they are suspended between two continents as they navigate the narrow gap.

2.3. Diving Conditions and Safety

While the diving experience in Silfra is undoubtedly breathtaking, it is essential to be aware of the diving conditions and take the necessary precautions to ensure a safe and enjoyable dive. Here are a few key points to consider:

• The water temperature in Silfra is cold, so it is crucial to wear appropriate thermal protection, such as a drysuit, hood, and gloves.



• Given the unique nature of the dive, it is highly recommended to dive with a certified guide who is familiar with the site.
• Due to the low water temperature, divers should also be aware of the potential for cold water shock and take measures to minimize the risk.
• It is important to note that Silfra is a freshwater dive, meaning that divers will not need to worry about the usual saltwater buoyancy calculations.
• As with any dive, it is crucial to monitor your air supply, ensure proper buoyancy control, and adhere to safe diving practices.

2.4. Certification and Prerequisites

While diving in Silfra is suitable for divers of all experience levels, there are a few prerequisites to keep in mind:

• All divers must be certified and have a minimum of 10 logged dives, with experience in cold water and drysuit diving recommended.
• Divers should bring their certification card and logbook as proof of their qualifications.
• For those who have never dived in a drysuit before, it is highly recommended to take a drysuit specialty course before diving in Silfra to ensure familiarity with the equipment and techniques.

2.4.1. Snorkeling in Silfra Fissure

If diving is not your cup of tea but you still want to experience the marvels of Silfra, don’t worry! Snorkeling in Silfra is also possible. Snorkelers will get to explore the surface of the fissure, admiring the crystal clear waters and the underwater scenery from above.

Snorkeling in Silfra is suitable for non-divers and provides a unique perspective of the fissure. Participants will be provided with all the necessary equipment, including a drysuit, to ensure their comfort and safety throughout the snorkeling experience. It’s a fantastic option for those who want to get a taste of the Silfra Fissure without venturing into the depths.

3. The History of Silfra Fissure

While Silfra is primarily known for its diving and geological wonders, the fissure also has a rich historical background. The Þingvellir National Park, where Silfra is located, holds immense cultural and historical importance in Iceland. The park was the site of the Alþingi (Althing), the world’s oldest existing parliament, which was established in 930 AD.

The assembly, which met annually, was responsible for governing Iceland and making important decisions for the country. Each summer, representatives from all parts of the country would gather at Þingvellir to discuss legal matters, resolve disputes, and establish laws. This important historical site reflects the democratic traditions and heritage of the Icelandic people.
