Schnorchel Silfra, Caving & Nordlichter

Gehen Sie durch Lavaröhren, schwimmen Sie zwischen Kontinenten und beobachten Sie Nordlichter

Snorkel through lava filtered water, walk where lava flowed

On this self-drive tour, you will snorkel through one of the world’s most fantastic snorkel and dive sites, Silfra, and go hiking through a lava tube that was created thousands of years ago by a river of red glowing lava! Additionally, you will observe the Northern Lights in a way that is not possible anywhere else. This tour combines our top rated Silfra Snorkeling Tour with a caving tour through a lava tube and a visit to the unique Aurora Basecamp.

The lava tube you will visit is called Leiðarendi cave. Leiðarendi displays the typical features of this most common type of lava cave in Iceland. It is full of utterly weird and wonderful rock formations as well as a splattering of amazing colors. Even though at some points inside the cave we will have to climb and crawl a little, this cave tour is an easy one that 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.

You will see another feature of tectonic activity from another and most unusual perspective: underwater! Silfra is a fissure created by the Eurasian and North American tectonic plates pulling apart. The fissure is filled with crystal clear glacial water that has been filtered underground for decades. This is an underwater scene unlike anywhere else on earth. You can read more about the Silfra snorkeling tour here.

Aurora Basecamp is a Northern Lights Observatory where you will experience a unique indoor simulation of the Northern Lights as well as learning about hunting them in the Icelandic sky. At Aurora Basecamp you will also get tips on how to spot them, how to take photos of them on your camera and much more. The visit will be during the day, but your voucher allows you to visit again the same night, a perfect starting point if you plan to hunt for the Northern Lights while in Iceland.

This is a combo self-drive tour. Meeting point for Silfra Snorkeling is at Thingvellir national park. The drive from Reykjavik is about 1 hour. Meeting point for the Cave and Northern Lights tour is at Aurora Basecamp. The drive from Reykjavik is about 20 minutes. Daily departures at 15.00 / 3PM.

"What an amazing experience! While we were super excited about the idea of doing this, the reality was a bit daunting. It's cold, it's a bit confining, but wow was it worth the slight discomfort. Our guide Tanya was amazing; personable, funny, helpful, calming, I could go on. As a quasi-seasoned snorkler, I can say that you will never see anything like this anywhere. Do this tour with if you have the chance."
