Pinnacle Peak Park is a 256-acre volcanic cone that rises straight out of the Enumclaw farmlands and straight down to the White River. Also known locally as Mt. Peak, and even Mt. Pete, Pinnacle Peak is one of the most popular hikes for Enumclaw and South county families. A one-mile long forested trail climbs 1000-vertical feet to the top of the 1800-foot geological knob. Once you get to the top, you will see extruded outcroppings of columnar basalt, concrete footings of an old fire lookout and best of all, spectacular views from the south side of Mt Rainier and the White River valley.

The trail is named for Cal Magnusson, a long time Cascade mountaineer who worked at REI for 25 years with famed mountain climber Jim Whittaker. A recent acquisition of 83 acres on the south side of the park provides another access to the peak along gravel roads and even more spectacular views along the way. The new acquisitions also present an opportunity to develop an equestrian trail and other recreation amenities.

Acreage: 334

Trail length: 4 miles
