Trail guide
Cathedral Spires Trail is a 1.2-mile out-and-back from the Needles Highway hairpin into a basin ringed by granite pinnacles. The current signed route usually takes one to two hours. Most of the walk is a forest approach; the last stretch climbs steeply over boulders into the spires. An older 2.3-mile figure also circulates, but it does not match the shorter, currently mapped trail to the basin.
The first part is mostly gentle walking through ponderosa pine and spruce, with the rock towers coming into view between the trees. Switchbacks lead toward the final, much steeper section. Expect large, uneven boulders underfoot and take your time here. Follow the trail markers: the paths connect into longer hikes near the basin.
The payoff is getting close to the tall, narrow rock pillars rather than viewing them only from the highway. They were shaped by erosion over millions of years and are protected as a National Natural Landmark. Their organ-pipe profile is what gave the Cathedral Spires their name. Late-afternoon light brings out the texture in the granite.
The Cathedral Spires route meets Black Elk Trail #4 and the Little Devils Tower trail. Those connections make longer outings possible, but they are extensions, not part of this short basin hike. For the route described here, turn around at the marked junction and return the way you came.
Start at the signed pull-off on Needles Highway at the sharp hairpin, about a mile east of Needles Eye Tunnel. Parking is limited. Park admission is required. Dogs are allowed in the park on a leash no longer than 10 feet.
