McKenzie River Ranger District

The McKenzie River Ranger District is in the middle part of the Willamette National Forest, bordering the Deschutes National Forest. Accessible from the west via Highway 126 from Eugene, Oregon, or from the east on Highway 20 from Sisters.

The McKenzie River Ranger District is a collection of stunning lakes and waterfalls, epic mountain biking and rafting, and opportunities to explore history.

Hiking: Get your water fix at the Upper McKenzie Trail Area hiking the Water Falls Loop Trail #3503 where you can see the popular Sahalie and Koosah Falls. View the headwaters of the McKenzie River at the stunning Clear Lake Loop Trail #4341.

Other Recreation: The O’Leary trail complex and Upper McKenzie Trail Area offer some of the best mountain biking on the forest. Road cyclists will love the challenge of the McKenzie Pass-Santiam Pass National Scenic Byway and the views are spectacular from your vehicle as well!

Don’t miss the Dee Wright Observatory, along the scenic McKenzie Highway (Hwy 242), for panoramic views of Cascade peaks such as Mount Washington and the Three Sisters. For Highway 242 opening and closing dates, check the Oregon Department of Transportation website.

History buffs will enjoy a stop at Fish Lake Interpretive Day Use sites, or try spending a night at an historic guard station (reservations required) such as Box Canyon Guard Station or Indian Ridge Lookout.

Take a guided trip down the river with one of our McKenzie River Permitted Outfitters and Guides.
