This small-group tour, limited to 6 participants, ensures an intimate experience with personalized guidance. Your PADI-certified guide provides a thorough introduction to snorkeling techniques and equipment use, making sure everyone feels comfortable before entering the water. The guides are praised for their friendliness, expertise, and calmness, which helps ease nerves, especially for first-timers.
Once at Silfra, you’ll change into a dry suit—which is worn over warm clothing—and learn how to handle your snorkeling gear. The dry suits are specially designed for the cold Icelandic water, allowing you to float comfortably in waters that are only 1-2°C (34-36°F). Many reviews highlight the guides’ attentiveness and the safety measures that make the activity accessible for most participants.

The main attraction of the tour is the chance to float between the tectonic plates in the deep, narrow fissure called Silfra Big Crack. The water clarity is extraordinary, often exceeding 328 feet (100 meters), which means you can see the underwater rocks, algae, and plant life in sharp detail.
Guides lead you through the Silfra Hall, a wider fissure, and into the Silfra Cathedral, a deep section with impressive rock formations. The float over boulders and the view into Thingvallavatn Lake evoke a sense of being in a different world—an environment unlike any other on Earth.

Participants are advised to wear long underwear and thick wool socks under the dry suit for added warmth. The dry suits are designed to keep you dry and insulated, though some reviews note that they can feel tight and constricting. The wet suits are not used in this tour, emphasizing the importance of proper layering.
The entry and exit involve stepping into the water using designated stairs, which is straightforward but requires some effort. The guides provide a comprehensive orientation before entering, ensuring everyone understands safety procedures and how to manage the equipment.
The water is cold, but the dry suits effectively maintain warmth. The tour includes hot chocolate and cookies afterward, perfect for warming up after your underwater adventure. Some reviews mention that dressing in layers and being prepared enhances comfort and enjoyment.

The actual snorkeling lasts around 30 to 40 minutes, with the total experience taking approximately 4 hours and 30 minutes from pickup to return. The small group size means a more personalized pace, but guests should be prepared for a wait outdoors in cold temperatures during the briefing and gear-up process.
Transport issues are occasionally noted in reviews; some mention delays or uncomfortable bus rides, so planning accordingly is wise. The pickup and drop-off service simplifies logistics and saves the hassle of navigating Iceland’s roads.

All necessary snorkeling equipment is included, with dry suits and warm undersuits provided to handle the icy waters. The guides are PADI-certified, ensuring professional instruction and safety oversight. Many reviews emphasize how well-managed the equipment fitting process is, with helpful staff assisting with suit adjustments.

The tour is suitable for anyone who is comfortable swimming, physically fit, and healthy. The minimum height and weight requirements are 150cm and 45kg, with a maximum of 6ft 7in and 120kg.

Post-snorkeling, guests are treated to hot chocolate and cookies, which offer a comforting and warming end to the adventure. This small touch receives positive mentions in reviews, as it provides an opportunity to share the experience and relax after the cold water.
There are no other food or beverage options included, but the provided refreshments are enough to re-energize before the return journey to Reykjavik.

The main strength of this tour is the unique opportunity to snorkel between tectonic plates in a setting renowned for extraordinary clarity and vivid scenery. The guides’ professionalism and equipment quality consistently receive high praise, making the activity accessible even for those new to snorkeling.
However, waiting times outdoors in icy conditions can pose a challenge, particularly during busy seasons or if logistical issues arise. Some reviews note that the process of suiting up and briefing could be more streamlined. Participants with claustrophobia or discomfort in tight suits should be aware that the dry suits can feel tight and constricting.
The cost of $194 offers good value considering the equipment, guides, and transport included. The tour’s small-group format enhances safety and personalization, but it can be affected by delays or crowding at busy times.
This Silfra snorkeling experience stands out for its geological rarity and visual spectacle. It suits adventurers eager for a unique environment and those comfortable with cold water activities. The expert guidance helps ensure safety and enjoyment, even if you’re new to snorkeling or dry suits.
The all-inclusive package, with hotel pickup, quality equipment, and refreshments, makes it a hassle-free way to enjoy a one-of-a-kind Icelandic landscape.
