South coast.
Stenstugorna (the stone cottages) is a small south-facing wall by the sea with two small caves. There are several trad routes from 5.5 to 5.11; the more difficult ones start in the caves. There are numerous options for building anchors, but the easiest is to sling the big block at top and extend to the lip.
Park in large lot before the road ends at the light house. Follow path from lot south past designated camping area through forest, across wooden planks. Continue down hill through gate and turn right (west). Stenstugorna is the next wall toward the lighthouse from Åkersberget. Follow trail west another ~200 m. Either scramble down to base of the wall here, or continue ~50 m further then left to overlook. Rap from here, or scramble down either the west side (easier) or east side to the base.
