The Rundlehorn is a classic climb almost inside the town of Banff. It is a meandering 11-pitch 5.5. To access the route, drive toward the Banff Golf Club. From town you head toward the Fairmont, but take the Bow Falls exit. Drive through the falls parking lot and across the bridge. About 500 meters down the road there is a pullout on the right hand side. A trail begins behind the lot, but to be honest you can basically just start heading up. There are so many trails, it's a pick-your-own-adventure sort of thing. You are aiming for a scree triangle. As you get higher, the trails converge. The start of the route can be tricky to find. Look for the bolts; they start about a 80 meters bellow the end of the scree triangle. You can leave your shoes here, although approach shoes are better than climbing shoes for this route.
The route meanders diagonally up toward the crest of the ridge. The rock is limestone, but there are calcified features that make for excellent holds on the slab. It's run out but very easy climbing. The pitches here can easily be linked because they are quite short. Eventually you gain the ridge and it's a scramble up very loose scree to the next. Next to a very sappy pine tree you will find a gap in the rock band. Bolts can be observed higher up. This is defintiely the better half of the route, though the route finding is less obvious. Eventually it gains a broad, flat open area large enough to pitch a tent, and you're at the top.
