This crag is on San Ildefonso Pueblo. MORE INFO >>>


A south, east and SE facing cliff of dirty, pocketed basalt. This crag is opposite of the North side of The Overlook. Currently has ~5 bolted routes and a few pointless cracks.

This crag is so-named due to its proximity to a sewage treatment plant. The climbing is not particularly stanky, nor is the surrounding environment. A good place to go if you want a bit of seclusion. The routes would be really good if they ever got cleaned up, but that seems like an awful lot to hope for.

Getting There 

The approach is much shorter, easier and cleaner than all of the area guidebooks imply. It took me ~15 minutes, and I never had to 'ford a foul smelling stream'.

Park at the Overlook. Walk N from the P-lot and locate the Sewer crag visually across the canyon. Note the creek you will need to cross, and identify the approach route, which basically traverses the canyon rim until you are almost above the Sewer Crag, then descends a grass covered talus field to the base of the wall.

Walk back up the road the way you came for about 100 yds to a large clearing on the N side of the road. Bushwhack NW for 100 yds into thickening brush, and pick up a faint trail that leads to a stream crossing near the large waterfall. It is trivial to cross this stream without getting your feet wet. Once across the stream, continue on a much better trail N, then NE, then E along the canyon rim. After ~ 200 yds a subtle cairn appears on the right, about 30 yds S of the trail. Walk to this cairn, and descend the bushy talus field below to the base of the cliff. First bolted route encountered is "Toxic Avenger".

Though this route appears to be squeezed into the shallow dihedral between "Fecal Antimatter" and "Septic Maiden", it's actually a fun, independent line and is the best warm up at the Sewer crag. The climb begins on large, slightly loose blocks. The holds become progressively smaller and less positive, presenting the thin, technical crux around the fourth bolt. After this, the difficulty eases, and the route follows fun stemming and crimping moves up the dihedral, past a small roof, and to the ...[more]   Browse More Classics in NM

Better parking beta for the Sewer Crag is to park at the RC car track on the right side (south side) of the Overlook road just before the main Overlook parking area. Do not park at the county sewage facility parking area, please.

This is a fun little area that deserves a visit from the 11+/12- climbers. I lump it in the same gray area of access as The Y and Potrillo Cliffs in that I really don't think it's a problem to be climbing there despite not being on public land. The trail above the climbing area clearly sees a lot of traffic likely from nearby residents walking their dogs.
