Reviews on TripAdvisor


"Before we climbed through the narrow opening of the cave, our guide reminded us that today we were cavers, not tourists. That set the stage for the entire tour. Unlike other cave tours, there wasn't a man-made path through the cave and the only light came from our flashlights. There were points in the cave where it was so narrow that we actually had to crawl through. But our guide was experienced and reassured us that we were all capable of making it through. We would definitely do the tour again!"

Tour Description

lava tube cave iceland

Enjoying the underground experience

Cave Leidarendi is about 900 metres long and is situated in a lava field near a volcanic crater south-east of the town of Hafnarfjordur. It was first mapped in 1992.

We will enter through narrow cave entrances and find they open out to reveal an extraordinary scenery of lava formations and unexpected colours.

We will see interesting forms of lava stalactites and different rock formations making this an experience of majestic and almost indescribable beauty. The cave becomes wide and high in some places and with an even floor. However, the trip can also be tricky at times, since we need to crawl in a few places.

We recommend you wear good walking shoes or hiking boots which are suitable for walking on uneven lava surfaces.

Shedding light into earth's interior - simply amazing

Stóri-Bolli (Big-Cup), is scoria crater and is about 150 metres in diameter. Around 2000 years ago an eruption started in Stóri-Bolli and from it flowed its namesake lava field, Stóra-Bollahraun and the lava tube Leidarendi was created within this.

We will see the craters from the site of the cave. It only takes 25-30 minutes to drive to the cave from Reykjavik and the cave's entrance is just a short distance from the road.

The Lamb

When the cave was discovered there was found deep in the cave a skeleton of a little lamb that had stumbled or fell in to the cave at some point. This skeleton is still inside the cave and we will have the opportunity to see and observe the skeleton.

Nobody knows how this little lamb got in there but we sure know it had difficult times in the total darkness.

Caving experience

We'll be using hand-held flash lights and headlights. Most of the time you can choose which one you prefer.

This tour is suitable for all who can walk on uneven surfaces and at times, on all fours.

The cave's ceiling and walls are broken or collapsed in very few places and it is therefore easy to navigate. Although sometimes the cave’s ceiling gets a bit low so at times you might have to crawl for a short distance.

Leidarendi lava tube is considered to be a subterranean wonder world. The entrance is a small pit that leads down into the cave; the cave itself runs in both directions and connects in two parts so it runs as a line with a circle in the middle.

Unpolluted Nature

Respect for nature and safety are our main concerns. There are no handrails, lights or any tools installed in or around the caves. We rely completely on the equipment we carry and it is important that people respect our guidelines.

You don't need to be afraid to go caving in Iceland; Cave Leiðarendi hasn't changed in over 2000 years!
