Denman Peak is located in the Tatoosh range along the southern boundary of Mt. Rainier National Park
in Washington State. Another prominent, if lesser, peak in the Tatoosh Traverse
, Denman, lies just northwest of Plummer Peak
, and just east of Lane Peak
. Denman is an easy scramble and has great views of the surrounding peaks and Mt. Rainier
across the valley to the north. This peak is a slight notch harder than Plummer (e.g. off-trail) and likely receives fewer visitors. The easiest approach is via the Pinnacle Peak trail and following a user path across the north shoulder of Plummer.
Denman Peak could easily be combined with climbing Pinnacle Peak
, Plummer, or other peaks along the Traverse for a full day outing.
From the Nisqually (southwest) entrance to Mt. Rainier National Park, follow Hwy 706 past Longmire towards Paradise, turning off for Ohnapecosh. Continue on a short distance to a roadside parking area at the Reflection Lakes
. On the opposite side of the road is the Pinnacle Peak trailhead.
must be paid on entering Mt. Rainier National Park.
When To Climb
Denman is probably best in late-spring/summer/fall -- although it can probably be climbed all year 'round. Access in winter may be trickier -- the road is generally plowed up to Paradise, but the section down to the Reflection Lakes may be closed - requiring a much longer snow approach likely requiring snowshoes.
There is camping permitted within the park. The closest car-campground is at Cougar Rock between Longmire and Paradise. A back-country permit
(available at the Wilderness Information Center in Longmire) is required for camping up on/near Denman.
