On Hwy-18, 10 miles North of San Bernardino. The rustic community of Crestline, mostly concealed along winding forested lanes, is no appeal whatsoever except as a start (or end) point of the Rim of the World Drive. From here, heading left (through the Valley of Enchantment) leads to Silverwood Lake State Recreation Area, turning right (through the Valley of the Moon) leads to Lake Arrowhead.
