Riley Campground is an equestrian facility located northwest of Oregon's majestic Mt. Hood. Horse corrals are tucked into the forest near the campsites, and several horseback riding trails can be accessed from the campground. A variety of recreational and sightseeing opportunities are available for visitors to enjoy. Several hiking, biking and horseback riding trails can be accessed from the campground, including the 5.3-mile Cast Creek Trail, which was reconstructed in 1998 and leads from the campground to the Zigzag Mountain Trail. Combined with the nearby 4.9-mile Horseshoe Ridge Trail and part of the Zigzag Mountain Trail, visitors can make a nearly 14-mile excursion. The Sandy River Trail follows the river and stretches about 3 miles.
Fishing is available in nearby Lost Creek, as well as the Sandy River, which is not far from the campground.
