Hanshallaren has become famous all over the world for being a crag suitable for the strongest climbers. But you will also find routes for the regular climber there: ranging in difficulty from 4c to 9c ("Silence", being the world's hardest route). Hula (the cave) consists of hard and pure granite, and you can climb there even if it rains.
All climbing fields dries up quickly after rain, as it saves heat in the granite, and you can basically climb all day in the middle of summer.
Parking in designated area.
