Meeting at Thingvellir: Starting the Dive in Iceland’s Geological Heart

The tour begins at Silfra meeting point within Thingvellir National Park. Travelers meet at the designated parking lot, with a small parking fee of 500 ISK for private cars. The location is easily accessible and well-marked, with clear instructions provided ahead of time. The guides arrive prepared to assist in gear fitting and safety checks, setting the tone for a professional and friendly environment.

This start point offers breathtaking views of the park’s rugged landscapes and volcanic formations. The briefing session covers dive procedures, signals, and park regulations, ensuring everyone understands safety protocols. It is here that divers also get acquainted with their dry suits, masks, fins, and tanks.

Essential Equipment and Safety Measures for Silfra Diving

All diving gear is included, such as dry suits, masks, fins, thermal undersuits, tanks, weights, and regulators. The dry suits are key to handling the cold water temperatures—which range from just below freezing in winter to slightly warmer in summer. The guides emphasize proper safety checks and weighting before descending into the water.

The descend involves a ladder leading to a metal platform, where divers stand in waist-deep water to adjust equipment and perform final safety checks. A taste of the pure, drinkable water is encouraged here, highlighting the exceptional clarity of Silfra’s waters. The guides are attentive, helping with gear fitting and ensuring all safety standards are met.

Navigating the Spectacular Underwater Terrain of Silfra

The dive route includes Silfra Hall, Cathedral, and Lagoon. Each location offers a distinctive scene, with crystal-clear water visibility often exceeding 328 feet (100 meters).

• Silfra Deep Crack: Swim through a narrow fissure between the continental plates; this space often feels like floating in a surreal, underwater corridor.
• Silfra Hall: Enter a vast cavern with sheer lava walls and impressive geological formations. The plug of water here is a favorite for its electric blue hues.
• Silfra Cathedral: The deepest point at 72 feet (22 meters), where the lava walls create a dramatic chamber with endless visibility.
• Silfra Lagoon: End your route at a brilliantly blue lake of pristine water, giving an almost otherworldly feeling of swimming in a liquid gemstone.

Divers glide through widening cracks, marvel at the translucent walls, and enjoy the serene silence beneath the water. The guides lead carefully, ensuring each diver experiences the beauty and tranquility safely.

Winter vs. Summer Dives: Adjustments and Expectations

During summer months, the tour offers two 30-minute dives, giving more time to explore the underwater sights. In winter, if water temperatures drop below freezing, the tour adapts to a single dive of approximately 45 minutes. Safety is prioritized, with guides adjusting the plan if temperatures threaten comfort or safety.

The dry suits provide warmth regardless of season, but the water remains cold, so warm clothing and thermal underwear are recommended for after the dive. The shorter winter dives mean less time submerged but still allow for spectacular scenery.

Walking Back to Shore and Post-Dive Refreshments

After completing the underwater route, divers ascend from the water, remove their fins and heavy equipment, and walk back to the parking lot. The changing area is not specified explicitly but is implied to be nearby for convenience.

The tour concludes with a hot chocolate and cookies break, providing a warm, comforting end to the adventure. The small group setting fosters a relaxed atmosphere, allowing for sharing experiences and asking questions about the underwater formations or the geology of Silfra.

The Small Group Advantage and Guide Expertise

This small-group experience is capped at three divers, ensuring personalized attention and focused guidance. Guides are PADI-certified, with many praised for their knowledge, enthusiasm, and supportiveness.

Guides like Francesca, Wilmar, and Fede stand out for their energy and dedication, helping nervous divers feel at ease and enjoy the experience fully. Their expertise makes the underwater exploration smooth and safe, even for those with some prior dry suit experience.
