The next pull-off is Agua Canyon, one of the finest vistas in the park. Massive hoodoos stand close to the rim; farther off are the vividly colored Pink Cliffs; and on the far horizon is the domed profile of Navajo Mountain, over 10,000 feet [3,048 meters] high.
Continue to the end of the road at Rainbow Point. Stop here for a picnic among the thick stands of fir on the park’s highest elevation, 9,115 feet [2,778.3 meters]. A pleasant mile [1.6-kilometer] walk follows the Bristlecone Loop Trail to expansive views. A spur trail leads to more views at Yovimpa Point; the cliffs that descend from there in stairsteps are named for their rock colors—pink, gray, white, vermilion, and chocolate. A stand of ancient bristlecone pines grows on the exposed edge of the plateau; the oldest in the park has been alive for more than 1,500 years.
Acoustic studies have found that the natural silence here equals the quality of a sound studio. Park air is superb, too. But rangers worry that this purity will be threatened by possible development on adjacent lands.
