Getting Oriented
Lolo Pass sits 6 miles northwest of Mount Hood and 10 miles northeast of Zigzag. The south approach leaves US 26 at the Zigzag Ranger Station and climbs through old-growth Douglas fir to the pass. The north side drops down the Hood River watershed through Lost Lake and out to Dee, where pavement returns and OR 281 carries traffic into Hood River.
The pass is significantly lower than Bennett Pass on OR 35, which made it the historic route for travelers crossing the Cascades north of the mountain. The Pacific Crest Trail crosses the pass at the high point, with the Lolo Pass trailhead serving as a popular access for through-hikers.
Trail Overview
Thirty miles of mixed pavement and gravel, point-to-point. The southwest segment from Zigzag to the pass is paved and signed; the northeast descent is graded gravel with washboard sections, narrow stretches, and occasional one-lane pinches. There are no technical obstacles, but the surface deteriorates in the rain and the road closes from snow most winters.
The forest service does not actively maintain Lolo Pass Road for snow and ice. Closure dates vary year to year; expect the gate at the pass closed from December through May.
Points of Interest
- Lolo Pass summit (3,415 ft). PCT crossing with parking, an information board, and views toward Mount Hood from a short trail off the lot.
- Lost Lake. Major Forest Service reservoir on a paved spur off the north descent. The Lost Lake Resort, two campgrounds, and trail system around the lake make it a worthwhile stop.
- Bull Run Watershed boundary. The road's south side passes the boundary of Portland's drinking-water watershed; the watershed itself is closed to public access.
- Old-growth Douglas fir. Several stretches on the south climb run through stands of mature Douglas fir worth pulling over for.
- Dee covered bridge area. Near the road's north end, the East Fork Hood River runs through the Dee mill site; pavement returns here.
Where to Camp
Lost Lake Campground (Forest Service, 99 sites) is the largest developed option directly off the route, on a paved spur from the north side. Riley Horse Camp, McNeil Campground, and Lost Creek Campground sit on Forest Road 1825 near the south entrance to FR 18. Dispersed camping is allowed on Mt. Hood National Forest land along most spur roads.
Tips for a Safe and Enjoyable Trip
- Confirm the road is open before driving. The Hood River and Zigzag ranger district offices hold current status.
- The gravel north side gets slick after rain. Drop tire pressure if the surface turns muddy.
- The road is narrow and can pinch to one lane. Slow down for blind corners and yield to oncoming traffic.
- Combine with the Mt. Hood Scenic Byway for a longer loop based out of Hood River or Sandy.
- Lost Lake is a popular weekend destination from Hood River; expect busier traffic on the north spur in summer.
