Flag Mountain Trail #766


Flag Mountain

Flag Mountain Trail offers a few excellent views of Mt. Hood. Dogwood and Rhododendron bloom abundantly here in June. This lower elevation trail is free of snow much of the year.

From its northwestern end, this trail climbs steeply for almost ½ mile until it reaches the ridge. This section may be too steep for most bikers. Once on the ridge, the trail has a gentler grade, but still gains and loses elevation. For bikers, the trail is a narrower single track trail, and can be challenging on the ridge.
