Pacific Coast Trail: Mount Washington Wilderness

The Mount Washington Wilderness section of the Pacific Crest Trail is one of the most unique sections of the entire 2,650 mile trail. You’ll cross relatively recent lava flows, having occurred just 1,500-3,000 years ago. A short side trip can also take you to the top of Little Belknap Crater, one of the small shield volcanoes responsible for the flows.

This hike might not be for everyone however, as crossing the lava fields require study footing and good shoes. There is also limited shade and no water sources.

Begin the hike from the Pacific Crest Trailhead at Big Lake, near Big Lake Youth Camp. If you are just day hiking there is no need to acquire an advance permit. Follow the PCT as it gradually climbs through the forest, eventually wrapping around the west side of Mount Washington.

You’ll soon enter the lava fields, but will then have a break as the trail crosses an enjoyable, lightly forested section. This is the last spot to enjoy shade or camp (permit required) before the final lava flow section.

Reenter the lava flow and head toward Little Belknap Crater. There is a short side trail that leads to the summit, a highly recommended side trip. From the summit you’ll have 360 degree views of the volcanic landscape.

It is then all downhill, but still slow going through the lava field.

Continue until the lava field pauses just before you arrive at the Pacific Crest Trailhead at McKenzie Pass. This is the end of the section, but if you have the time I’d also recommend walking a short distance up the road to the Dee Wright Observatory.
