The West Side has more of an adventurous feel to it. Many of the multi-pitch routes have a (no-longer-deserved) reputation for loose rock and scary bolts. Nearly all routes have been re-bolted with modern/bomber hardware. Much of loose rock has been cleaned off over the years. The setting of many routes more than offsets the occasional loose hold.
Please be respectful of other users of the West Side. Climbers have spent many years developing a working relation with the NPS. Please stay on the marked use-trails and leave the loud boom-boxes at home.
Please be aware of closures for birds from MLK Day to early July: https://www.nps.gov/pinn/planyourvisit/advisory.htm
