Kor-Ingalls was made famous by the book 50 Classic Climbs of North America, and it’s for a good reason. Castleton Tower is a must do desert spire that attracts climbers from all over the world. The Kor-Ingalls route is the most popular climb on the formation and follows a huge corner splitting the South face. All belays are very comfortable, the rock is mostly solid (but beware of the occasional loose block), and it demands a good variety of techniques, including face climbing, stemming, chimneying, and jamming. The highlight of the route is the classic 3rd pitch chimney, where previous desert chimney climbing experience helps.

Kor-Ingalls protects relatively well, but you can’t always place pro where you want to, so don’t skip a good placement. This climb is very popular and can get hot. Come early, climb it in winter or be ready to climb something else. Good nearby alternatives include North Chimney (5.9-), Fine Jade (5.11a) and Honeymoon Chimney (5.11b or 5.9 A0). These routes are located just a few minutes away from Kor-Ingalls, and it's not too difficult for a competent party to climb two routes in a day.

Note that free campsites and wag bags (donation box) can be found at the trailhead to Castleton Tower. No water or toilets are available, and the space is limited.
