The Djupviksgrottorna (Grottan) is a bouldering paradise since the area is filled with beautiful routes on good holds with great landings. The lines often have a very steep or roof profile.
The area is full of many excellent routes like Martikainen 6C+, Hammas (RIP) 6C, and Voodoo 7A. There are dozens of easier and harder world class problems.
The best time to visit is during spring before the ticks wake up.
Grottan is slightly more than a 1 km hike from Soltuna and The path was remarked at 2016 and it is now well marked with arrows and rock cairns. The road leading to the area is privately owned and should not to be used.
