The Montclair area camps year-round, but each season changes what is open and how busy it gets. Spring, March through May, is the peak window for Chino Hills State Park, when green hills, poppies, lupines, and mustard bloom across the grasslands. Online reservations at Rolling M Ranch Campground open six months in advance through ReserveCalifornia and weekend dates fill quickly during this period. Summer brings hot, dry weather and the heaviest demand at lakeside and resort parks. Bonelli Bluffs RV Resort and Campground and Fairplex RV Park book out around holidays and major Fairplex events, including the LA County Fair. Fire danger climbs sharply, and open fires and charcoal BBQs are not permitted at Rolling M Ranch. The park closes for at least 48 hours following Red Flag warnings and quarter-inch-plus rain events. Fall cools down and crowds thin, making it a strong shoulder season. Winter is the wet season, with most annual rain falling between December and February. River-canyon access near Camp Williams Resort can be affected by storm runoff on East Fork Road.

Sites near Montclair fall into two clear groups. Resort-style parks like Fairplex RV Park and Bonelli Bluffs RV Resort and Campground offer paved pads, full hookups with 30 and 50 amp service, pools, laundry, and showers, but sites can feel close together and surrounding city noise is audible. Bonelli sites along the bluff have lake and mountain views; many do not include fire pits, and some lack picnic tables unless requested at check-in. Primitive and canyon sites are quieter and more scenic but more limited. Rolling M Ranch at Chino Hills State Park has 20 sites, flush toilets, potable water, no hookups, and a 30-foot RV length limit driven by a narrow access road. Camp Williams Resort sits on the East Fork of the San Gabriel River with shaded oak sites; cell service is spotty in the canyon and the access road is winding.
