Morning Alpenglow on Bath Rock from my campsite pa...
Bath Rock is an excellent area for beginners and even non-climbers. Thanks to the rangers for allowing rebar steps to be added to the west side. (Insert derogatory remark about rangers conservation vision here!!) The approach is none, and all faces have climbs. Difficulties range from 5.4 to 5.12a, with the majority on the easy end. A lot of sport routes also exist.
Due to the size of Bath Rock, areas have been broken up into four significant and isolated walls.
Park at the area for campsites or in the large, accommodating lot by the bathrooms.
Mountain Project's determination of some of the classic, most popular, highest rated routes for Bath Rock:
This is a simple route that starts directly across from the Bath Rock parking area. the route varies from guide book to guide book but basically as a 5.5 it runs straight up to a tree belay. The climbing involves moving from one large hand hold to the next. It is on the east face, and a little left of center. Descend via the back....[more]Browse More Classics in ID
Ditto that. They're not even sure when or who might have placed the rebar on Bath Rock. Might even pre-date most climbing in the area (ie, pre Alpenbock or Steinfell folks).
My guess is it's most likely a local effort done in conjuction with one of the old promotional events way back in the '30s to '50s or so. Whoever did it, actually did a nice job. For a climber, though, that down climb is pretty reasonable, although, would be spooky as an onsight downclimb.
