Aspeberget rises in a low ridge close to Litsleby and is the fourth main site of the Tanum World Heritage. The carvings here are scattered across a series of smooth granite outcrops — sun-wheels, boats, a famous panel of ploughmen with oxen, and one of the few clear depictions of a Bronze Age fishing scene.
A wooden walkway loops over the rock and information boards explain the most interesting panels. Free, open year-round, and rarely busy. Easy to combine with Litsleby on foot.
