The trailhead is a 30-45 minute drive from Oroville (depending on traffic). It is 5 miles from the trailhead on the upper trail. Elevation gain is about 1,200 feet - actually more gain on the way out. The lower trail is currently closed because bridges washed out. It is a well maintained trail with bridges, benches and mile markers - most people do it as a day hike. There is a nice free campground at the trailhead.
