Between the south ridge and the wedge there are several cliffs that make up "the mountaineers wall". The mountaineers wall hosts massive variety of near 200 climbs; with classic slabs, corners, aretes, faces, cracks, & some steep overhanging climbs as well. The area is an acquired taste, as the dirt, grass, & loose rock is complimentary to the diverse quality climbing. The mountaineers wall is in season on cooler days, but unlike the wedge, there are several crags that see afternoon shade, making a half day outing well worth the hike. The free topo on climbingtoposofsandiego.com (thanks CH) is great.

From the quarry road, continue past the raptor nesting sign that marks the turn for approaching the wedge. Within 100' or so there is another trail that branches off from the quarry road to the Mountaineer's side of the hill, it is well defined & is marked by a knee high boulder on your right. This trail links up all the larger boulders as it gently climbs its way upwards, & is pretty enjoyable and aerobic as compared to the wedge approach. 1st tier approach can be done in 30-40 mins if you keep your head down.

Once you are high on the MW this elaborate cliff band becomes an adventurous series of chutes and ladders. Loose rock can exist so always take caution. The locals have left a nice series of little metal signs at most of the junctions in the trail to let you know where you are.
