Lava Tunnel Caving & Snorkeling in Silfra with Transfer | Free Photos

About this activity

Combining snorkeling and caving gives you the ultra experience of Icelandic nature. You will explore the hidden world of the lava fields on foot and underwater. The cave we will visit is called Leiðarendi. The 900 meter long lava tube offers unique rock formations, such as stalactites and shelves.

Some light crawling may be required yet Leiðarendi cave has a rather easy access to the underworld wonders of the Icelandic lava fields.

Snorkel in between two continents at one of the top diving sites in the planet! Silfra is located in Iceland’s National Park, Thingvellir, and is a fissure that was formed by the divergent tectonic drift of the Eurasian and North American plates. What makes Silfra exceptionally unique is not only its geological significance, but it is also world-renowned for its crystal clear, fresh glacial water.

No diving experience or diving license is needed for this experience, and all the gear that you need is provided.
