Surtshellir — Attraction in undefined

This was an amazing experience, but on the edge of our comfort zone. We arrived in a cold, windy day with not a soul in sight. So to make it easier, we walked all the way along the path past holes 1, 2 3 and 4. Thst way, you know where you are heading.

We entered the lava tube at hole 4 - mainly as the distance between hole 4 and hole 3 is the shortest and gives you time to gain confidence. You can see the light from hole 3 almost as soon as you enter hole 4. Then hole 3 to hole 2 is medium distance = more confidence gained. Only a short way before the light of hole 2 comes into view.

Hole 2 to hole 1 is the longest and is amazing and you can truly appreciate it after gaining confidence being the the lava tube. It's a while before you see the exit, but by this time you are happy in the lava tube environment and can really enjoy it.

I hope this helps anyone else who arrives at the lava tube and is a bit daunted.

We didn't need a 4x4 for the road...

Visited 16th July 2025. We entered through entrance 1 and continued for a couple hundred meters to reach complete darkness, then returned. If you want a nice experience of going through the tunnel, make sure to have very sturdy shoes (not just soft sneakers), proper headtorches (no, iPhone light is not enough), warm and sturdy clothing (it’s cold down there and anything gets ripped easily). Caving helmet would be ideal but a woolly hat is better than nothing (if you bump your head against the rocks. For me good gloves were essential as you need to grab the rocks to climb over them and they are super sharp. It’s a mega cool experience, we were completely alone, the darkness is magnificent and who can say they climbed through Iceland’s longest lava tunnel eh? In other places on Iceland, you pay a lot of money for the guided tour but this is genuine hiking/climbing, and not elevated walkways with...

Great lava caves to explore. Sturdy boots with good grip and headtorch are essential. There are parts of the cave where no daylight reaches. It's possible to enter or exit the caves at holes number 1, 4, or 6 only. The caves are quite large, so you can stand up throughout the cave system. Some of the rocks inside are quite loose, so caution is advised. The carpark is right beside hole number 1. There is a pathway marked out above ground, so after going through the caves we took the overground path back. When we went, Google maps was confused between carparks 1 and 2 when we went, we took the road signposted on the road, and it brought us to the carpark at hole 1. The second carpark is just a short walk from holes 4 or 6. We went in mid September & roads were...
