Snorkeling Silfra & Caving in Thingvellir

Water and caves between the continents

Two perfect stops on the Golden Circle!

In just a few hours you will snorkel or dive in Silfra between two tectonic plates and take a walk through a tunnel created by the flow of glowing lava. You do not want to miss seeing the unique scenery on these adventures — it’s like nothing else on earth! These tours are a great addition to your self-drive Golden Circle tour or visit to Thingvellir Park.

Silfra is a fissure created by the separation of the North American and Eurasian tectonic plates. The fissure fills with glacial water that has been filtered through underground lava rock for decades. Once this water reaches Silfra it is crystal clear, providing over 100 meters of underwater visibility. The astonishing clarity allows for colors and views possible nowhere else on earth. As the water is 2°C-4°C year round, we will provide you with a dry suit and undergarment to keep you warm and dry in the water.

The lava cave system you will visit is called Gjabakkahellir. According to folklore, the caves are entrances to the ninth world or Niflheimar. At some points inside the cave we will have to climb and crawl a little, but this cave tour can be undertaken by everyone who feels comfortable in confined spaces and is fit to take a short hike. Please make sure to bring good shoes.

This is a perfect combination adventure for you if you want to get a truly in-depth view of our beautiful landscape and make the most of your day. You can read more about the Silfra Snorkeling tour here.

The schedule for this combination tour is as follows:

10:00: Snorkeling Silfra Tour – meet us at the Silfra parking lot.

Wir mieteten ein Wohnmobil entdeckt und waren alleine unterwegs. Dies war das einzige, was wir " geplant " der ganzen Woche, die wir dort waren. Wir hatten eine tolle Zeit! Jorgan war unser Führer und er war sehr informativ und unterhaltsam. Wir trugen zwei Schichten sowie verdoppelt bis auf Socken! Wir reisten am Anfang Oktober und wir waren nicht so kalt an. Es dauerte eine Weile, um sich in unsere Ausrüstung aber sobald wir das Wasser, es war das Geld wert! Das Wasser war so klar, es war wahnsinnig. So schön! ! Die heiße Schokolade und Kekse waren sehr zu schätzen am Ende der Reise!
