Snorkel through lava filtered water and walk where lava flowed
In one day 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! This tour combines our Silfra Snorkeling Tour with a tour of volcanic activity on the Reykjanes peninsula, including a hike through a lava tube.
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.
Prior to your hike in the lava cave, 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.
The Silfra Snorkeling & Lava Caving Tour is a great combination tour for those who want to make the most of their time in Iceland. Please note that the volcano and caving tour is operated by a trusted partner.

Amazing dive/lava caving combo
Enno and Eric did a wonderful job as our guides. Very helpful every step of the way. I dove and my girlfriend snorkeled. We were both very pleased with our tour. Our driver Stephano got big points too. While we were driving out to the park we saw a sheep that had tangled itself in barbed wire and was in great distress. Stephano made a quick u-turn to help free the poor little guy. Left a great impression for us. As for the diving, you will not see visibility like this anywhere else on earth. I've been to the Maldives, Red Sea, Micronesia, Palau, Belize; and this dive is still up there in my favorites. We also did the lava caving combo in the afternoon and we would highly recommend that as well. Didn't feel too "touristy". You actually have to get down on your hands and knees and do some crawling, and it is pitched black when you turn your torch off.

How long are we in the cave for?
We are usually underground for 45-60 minutes, depending on the speed of the group.
I use glasses, is that a problem?
Unfortunately it is not possible to wear glasses underneath the dive mask, as the mask would fill with water. We therefore advise that if you are near-sighted (i.e. you need glasses for distance), that you consider wearing contact lenses or bring your own prescription mask with you. If you are snorkelling and have prescription swimming goggles you are able to wear them, but you must also bring a nose clip to close of your nose, so that you are able to use your snorkel. If your prescription is not very strong (up to approximately -4) you may find that the natural magnification of the water will still allow you to see quite clearly. Should you need to purchase contact lenses, there are several opticians in Reykjavik where you would be able to do so.
