Hallstaberget is a fifteen meters high and 75 meters long crag with lots of different formations like; dihedrals, arêtes, roofs, overhangs, slabs and nice little cracks. That's quite unusual for Stockholm. This is not just a good crag for those who want to climb bolted routes in varying grades, it's also quite ok for beginners who want to practice traditional climbing. Although the cracks and corners are not long, they are clear-cut and well-defined. As a spice on the mash, there is also a unique little section (Left Wall) with pockets and edges which is taken directly from the 80's Buoux in southern France. Many routes have been bolted and fitted with anchors (2016). Some rarely climbed and poorly protected traditional routes have also been bolted.
The crag is located behind some trees in a field not far from the highway (you can hear the highway, but it's ok). Mostly ok rock quality, but some loose blocks exist, especially the right wall is more loose and broken. The ground on the left sector is flat and very children friendly. On the right sector, the ground is more bouldery and uneven. If you want to set a top rope, it's easy to get up on the crag via a path from both sides.
The wall is west and southwest facing, mostly open for the sun but with some trees that give shade here and there.
