State Route 243

California State Route 243

California 243 is a north-south state route that connects California 74 (Pines to Palms Highway) near Mountain Center with Interstate 10 in Banning via Idyllwild. Most of the route lies within the San Bernardino National Forest, following a National Scenic Byway through the forest. Elevations rise from 2,400 feet at Banning to 6,165 feet at Pine Cove and 5,400 at Idyllwild. Much of the route is a winding mountain road, with plenty of scenic vistas, hiking trails, and other recreational opportunities.

California 243 was established as a state highway in 1970, replacing former Riverside County Route R-1.1
