Using the 5.8mi (5% ascent) FR3512 to replace the 2.1mi (15% ascent) Tilly Jane Tr643 does reduce the grade to something more manageable, but the downhill is not worth such a long fireroad ascent, leaving this ride best suited for those able to manage a 15% ascent.

Depending on trail conditions, it may be possible to create a return loop with Polallie Ridge Tr643A (sometimes called Beargrass Path).

Be sure to check with the Parkdale Ranger Station on current conditions prior to riding either of these trails in the Spring or early Summer.

Nearby Dog Rvr Tr675 offers a more reasonable ride profile, with a long enough downhill to make the ascent worth the effort.

The Gunsight-Gumjuwac loop ride offers an even steeper downhill than Polallie Ridge Tr643A.

 

Mount Hood Wilderness Hiking

Timberline Trail 600, Pacific Crest Trail 2000-G and surrounding trails form a hub and spoke trail system around Mount Hood in classic Pacific Northwest trails circumnavigating Mount Hood with alpine vistas, waterfalls, alpine meadows and west side Cascade forest.

This section of the Pacific Crest Trail extends from Barlow Pass to Lolo Pass, with Timberline Trail 600 surrounding the north and east sides of Mount Hood at the treeline, from Yocum Ridge to Timberline Lodge.

Timberline Trail 600 was constructed by the Civilian Conservation Corps in the 1930’s, with challenging glacial-fed drainages crossing Newton, Coe, Muddy Fork, Sandy and White Rivers.

Wilderness permits are required and locator beacons are suggested. Mount Hood Summit info. Don't become a statistic, be prepared, especially if climbing above Timberline Tr600. Consider using a guide if not experienced climbing Mt Hood.

The Area Maps on the following pages cover most of this trail system Pioneer Bridle Trail 795 East Fork Trail 650, Sahalie Falls Trail 667C, Timberline Glade Trail 661.

Timberline Tr600 TopSpur east to Cloud Cap crosses Lad, Coe and Eliot streams, with late season snow due to northern exposure and well established campsites at Mcneil Point, Carin basin (stone shelter) and Elk Cove.

Elk Cove Tr631 offers open views of the northern Mount Hood. The upper section wanders gently along the broadening ridge, crossing a shallow stream, then following a drainage switchback to the Timberline Tr600 intersection.

Pinnacle Ridge Tr630 follows Pinnacle Ridge to the scenic timberline area of Wy’east Basin and the Barrett Spur. After several stream crossings on the way to the treeline, cross a wet meadow area, after which the trail becomes faint, then is reestablished in the woods. Cross alpine meadows on the upper section of the trail, with close views of Mount Hood snowfields and spurs.

Vista Ridge Tr626 combines with Eden Park Loop Tr600H and Timberline Tr600, and offers relatively quick access to Elk Cove, Barrett Spur, Eden Park, Cairn Basin and Wy'east Basin.
