The Stirrup Towers consist of a series of crags oriented northwest to southeast for a few hundred yards.

Individual rock formations on the west side, from north to south, include the (a) Star Trek Tower, (b) Frolic Towers, (c) Pyramid Tower and (d) The Stirrup.

 The routes are generally moderate in grade (5.8 - 5.10), on fairly good quality rock and are mixed or bolt protected.

The Mental Block, on the east side, sports two excellent bolted climbs that share the initial bolt and anchor. Paranoia (5.11b) ascends a steep face on edges while Manic Depression (5.11b) involves smearing on shallow depressions.

The Hand Grenade Corridor is near the north end of the Stirrup towers, east of the Frolic Towers and is hidden from view. The best routes are Hand Grenade (5.10a), a fun hand to fist crack climb and Horseshoe (5.11c), a steep, runout face climb to hand crack.
