Aftonroe on Guide's Rock has deservedly been a hugely popular climb for some time now. Descending parties have always had to rap down over others climbing the route in the past. There is now a designated descent which is entirely separate from the main climb and is mainly a walk off.
From the top chains of Aftonroe, make three rappels (30 m, 25 m, 25 m) on the climber’s right side of the Aftonroe climb to reach a good ledge. Note: you can bail from the top of pitch 5 on Aftonroe by traversing climber’s right on the same ledge but a large tree with long branches pushes you onto down sloping slabs with exposure.
Walk the ledge east (towards Banff townsite) sticking to the base of the steeper rock. There is a scuffed in trail with cairns and flagging marking where the trail zig zags down around a tree before heading east again to a fixed rope. The rope leads down a short step into a gully which is traversed to the far side (cairn). Follow cairns and flagging down the scuffed in trail until just above a main gravel filled gully. Instead of entering this gully which may funnel rock fall from others descending above, stay on the descender’s left, in and out of a smaller gully past more cairns until the main gully can be crossed lower down on a level trail which leads back west to the base of the climbs.
