Midway between Grimaren and Røysdalsnuten on Lifjell, by the beautiful mountain lake, lies a huge boulder against the rock. You may or may not have noticed it. It's easy to see, but as part of the rock. This has fallen off at some point in time and formed a large cavity on the inside. High walls (5-6 metres) on each side with a small entrance in the south and a slightly larger one in the north. Check this out next time you're in the neighbourhood.
