Forest Road 373 winds through ponderosa pine and oak woodland, connecting approximately 20 numbered dispersed sites along a bumpy but passable dirt loop. The road requires some clearance due to washouts and rocky sections, though campers report success with standard SUVs and even careful navigation in regular cars.
Site spacing varies considerably throughout the loop. Cody P. notes that "the first three campsites are nestled together," while sites further along the loop offer more separation. Site 4 backs up to hiking trails with vista access, making it popular with RV campers who can handle the approach road. Sites 16 and 17 accommodate larger groups with multiple trailers, though one reviewer found significant broken glass in the shared fire ring area.
Most sites include metal or stone fire rings, though seasonal restrictions often apply during dry months. The loop connects to hiking and biking trails, with some sites providing direct trailhead access. Cell coverage varies by carrier, with Verizon performing better than T-Mobile according to recent visitors. Wind picks up notably during morning and afternoon hours, creating substantial noise that some describe as waterfall-like.
Road traffic continues through evening hours, with vehicles passing sites until around 10 PM. The area sees steady use, particularly on weekends, though November through early spring typically offers better availability. Sites closer to the entrance fill first, while those requiring higher clearance toward the back of the loop remain open longer. Some sites show signs of heavy use, requiring cleanup of scattered trash and glass.
