Monterey to Redlands: Coastal Descent to Inland Empire

This 370-mile journey from Monterey to Redlands passes through 5 distinct climate zones, dropping from 50°F coastal fog to 100°F inland heat. The route follows Highway 1 south to Highway 101, then cuts inland via Highway 198 or 46 to Interstate 5, finally joining Interstate 215 to Interstate 10 east. One historical quirk: the stretch of Highway 101 through San Luis Obispo was originally part of the Camino Real, the Spanish mission trail linking 21 missions.
