Plummer Peak

Washington

About

Plummer Peak is a summit of 6,369 feet in the Mount Rainier Wilderness, within Mount Rainier National Park in Washington. The National Park Service manages the land, and the nearest town is Packwood, about 10.5 miles away. Summer is the most comfortable time to visit. Typical July highs reach about 62°F with lows near 44°F, based on averages from a nearby weather station at Rainier Paradise. That station sits roughly 900 feet lower than the peak, so temperatures up top run cooler. The Tatoosh Range, a climbing area, lies just 0.1 mile away, and Pinnacle Peak is about 0.3 mile off. For a longer outing, Mazama Ridge is about 1.4 miles away, and Cougar Rock Campground is about 2.8 miles away.
