This is where we originate from... The area all around the glacier contains hundreds of lava tubes, which makes the area really special for those interested in caves. Our story began few years ago when we started cave guiding in Vatnshellir Cave. That lead to fast expansion that has now made Summit Adventure Guides.We are the only tour operator that has permission to guide you into Vatnshellir cave, which is by now probably the most visited cave in Iceland. Vatnshellir was closed by the National Park few years ago for protection reasons and now it's only open with guidance from us, approved guides by the National Park.
The cave itself is an 8000 year old lava tube created by volcanic eruption from a nearby crater in the Purkhólar crater family. As the lava rushed down the hill in a lava river it began to cool on the surface, creating a crust on top of the lava river. As the eruption stopped, all the lava from underneath this crust continued to drain out. That eventually left behind empty tube with roof on top that gradually cooled down.
We offer 45 minute guided tours to Vatnshellir cave. It is one of the most easily accessible cave in Iceland, however you need to be reasonably fit to participate. Exactly how fit is difficult to say, but if you can walk up 2-3 story building without stopping and if you don't have trouble walking on uneven surfaces you should be fine.
You need to dress warmly for the cave tour, since the temperature is just above freezing throughout the year. Hiking shoes/boots are recommended but sneakers are acceptable. We will not permit high heels or flat-bottom shoes including flip-flops for this activity. Gloves are recommended for your safety and comfort. If you fall down, gloves can save your hands from the knife-sharp lava rock!
