A forerunner to the 'climbing gardens' of Graubünden. In Oldis near Haldenstein, this striking limestone slab rises 200 meters from the valley floor; it has been a playground for the Chur climbing scene from as far back as the 1950s. Othmar Stiegers route "Isabahn Schina", so named because the gear he used unmistakably came from SBB stocks, became a major early classic, and today holds one of the most 'worn out' cracks around. This varied and popular route is still a fantastic multi-pitch and can be climbed almost all year round. The previously quarried rock of Haldenstein is not always 'bombproof'. The single pitch routes are mostly very polished, requiring a precise and determined approach. During weekdays, work at the nearby wood storage facility can be noisy.

Occasionally, the criss-crossing of routes can be confusing. The Topo should provide some clarity - if it's even correct (many generations have left their mark here!)

Most of the routes are now well equipped with HSA-Inox-Bolts. You can also find all conceivable models of historic bolt-like-fixings here. Nuts and friends can be placed when older specimens cannot be trusted, though the smooth limestone here is also not the best for friends.
