Glenn Campground is a hike-in/bike-in accessible camping area located 6.

5-7 miles along a paved National Scenic Bikeway that parallels the West Fork San Gabriel River, featuring 10 campsites with picnic tables and fire pits, vault toilets, and several accessible fishing platforms for native trout fishing (catch-and-keep regulations apply below the second bridge, catch-and-release above).

Physically challenged groups can obtain a permit from the Glendora ranger office to drive to the campground; all visitors need an Adventure Pass or America the Beautiful Pass for trailhead parking and a California fishing license.
