Black & Blue - Caving & Snorkelling

This Iceland snorkeling and caving tour allows you to experience the country from a new angle.

We start a day with the black part of the tour by exploring a lava tube cave close to Reykjavík. We'll head to Raufarhólshellir, one of Iceland's longest lava tube caves. This adventure gives you great insight into the volcanic activities that have formed the country. After caving, you will have a chance to grab some lunch between the two activities. Next, we'll meet you at Þingvellir National Park (Thingvellir), where the Silfra fissure is found. Here we will put on our dry suits and get ready to explore the blue. Witness some of the clearest water on Earth as your guide leads you on a fascinating underwater journey.

Raufarhólshellir is a geological paradise renowned for its stunning minerals. Covered with colorful stalagmites and stalactites, this underground cave shows the fiery side of the land of fire and ice.

The longest lava cave in Iceland, Raufarhólshellir, spans 1360 meters long. No need to worry about crawling through tight spaces - the ceiling of this vast tunnel reaches 10 meters high. Lava tube caves are formed by a flash cooling process of lava that flows deep below the Earth's surface. Formed over 5000 years ago by the Leitahraun eruption, Raufarhólshellir is an ancient relic of a long-lost volcano. During the Raufarholshellir tour, you'll witness a place where time stands still. Marvel at the main tunnel ceiling where three stunning light beams shine, then continues to three small tunnels decorated with frozen lava. These spectacular rock formations are one of the best sights in Iceland!

Thingvellir is one of Iceland's most famous national parks. It is a UNESCO world heritage site and a historic landmark and geological wonder. Step back in time to the place where the first parliament (Alþingi) took place in 930. Today visitors can still find archeological relics such as the Lögberg or Law Rock and ruins of stone shelters. Perhaps its most remarkable feature, the park sits on a rift caused by the separation of two continental plates. The valley has rocky cliffs and fissures, such as the awe-inspiring Silfra fissure, world-renowned as a dive and snorkel site, where we embark on our underwater adventure.

Snorkeling in Silfra is a rare experience. Located between the Eurasian and North American tectonic plates, it is the only place in the world where you can swim between two continents. Dubbed the clearest waters on Earth, the visibility at Silfra reaches close to 150 meters for unparalleled views. Stare into the ocean's depths in a way you never have before. Your guide will accompany you as you drift through the peaceful waters. You'll soon see why this experience has been called liquid meditation. You'll also explore the underwater geology under these glacial waters. Touch lava rocks and observe Iceland from a different angle. This one-of-a-kind adventure requires no previous snorkeling experience and is sure to captivate all ages. Underwater pictures are taken by our guides during the tour so it is not necessary to bring a waterproof camera.

Participants need to be comfortable in the water and be able to swim. You cannot participate if you are pregnant due to the small risk of cold water entering the suit.

To participate in the tour, you must read and sign the medical statement form in our Snorkeling Handbook before booking. If you have any medical conditions, medical approval from a doctor is required.

Dry suit sizes: While we would like everyone to join our tour, our gear sizes reflect what is available on the market, and it is important guests are within the size parameters. This ensures the safety equipment can serve its purpose and keep guests from getting cold in the glacial water.
