Union Peak Professional Guide

Detailed Trail Description from our Guidebook

"Crater Lake National Park is Oregon’s only national park. The centerpiece, Crater Lake, is one of the deepest lakes in the world. It is the caldera of the ancient volcano, Mount Mazama, and the peaks surrounding the lake are all that remains of the mountain. Union Peak, in the southwest corner of the park, is a volcanic remnant and was first climbed in 1862.

The Pacific Crest Trail provides the well-maintained approach for this scramble. Although the scramble is on a trail, the upper section of the mountain is loose and the trail is difficult to follow. Note that the Park Service completely rerouted the Union Peak Trail, a project lasting three years that was completed in late summer 2003."

"Anyone who has approached Crater Lake National Park from the west has seen Union Peak. Just before the park boundary, at milepost 64 on OR 62, an immense black, steep-sided volcanic mountain suddenly looms in front of you. Almost immediately, the highway curves away and the mysterious peak disappears from view. It is never seen again—not from the highway or from any other road. The hike up Union Peak, the 7,709-foot sentinel of the park’s southwest corner, is one of Southern Oregon’s more challenging. The peak’s 800-foot-high rock pyramid sticks out like a boil amid much more level surroundings. The horrendously steep 0.5-mile final walk up the pyramid is immensely scenic, great fun (if exhausting), and well worth the lengthy trek to the base." Read more
