Ape Canyon Trail

Ape Canyon Trail Professional Review and Guide

"A mile-wide lahar scoured portions of the Muddy River valley, while other parts of the canyon offer you features created by eons of erosion from floods and long-forgotten mudflows.

The trail takes you in and out of several small side basins, each providing a unique thrill. Some are filled with wildflowers and ferns. Others are rich woodlands. All are alive with birdsong and critter activity."
