Hyllikeberg is steep for being Bohuslän. Despite its height of 10-15 meters you will feel your power running low before reaching the top. The crag is dominated by cracks through bulgy compact granite and the routes are in the seven span.
Hyllikeberg is southeast facing and is a good spot for afternoon climbing. It does no longer deserve its local name Mörkrets Hjärta (Heart of Darkness) after the clearing of the forest in front was done.
