State Route 243 (SR 243), or the Banning-Idyllwild Panoramic Highway, is a 30-mile (50 kilometer) two-lane state highway in the U.S. state of California that runs from Banning (in the north) to Idyllwild (in the south) in Riverside County. The highway is a connector between Interstate 10 (I-10) and SR 74. Along its route, it provides access to the San Bernardino National Forest. A road from Banning to Idyllwild was planned around the turn of the twentieth century, and was open by 1910. The road was added to the state highway system in 1970. From Wikipedia
