About This Drive
San Diego's driving roads are an underrated treasure. This route pack combines Palomar Mountain. a technical, engaging climb from 700 to 5,500 feet through 21 tight hairpin turns. with the Ortega Highway, Temecula Valley wine country, and the dramatic desert-edge roads of eastern San Diego County.
The South Grade Road up Palomar Mountain is the star: a series of tight, well-banked switchbacks through oak and pine forest that rewards precise driving. At the summit, the Palomar Observatory offers a unique stop before the descent. The route then loops through Temecula's 40+ wineries for an afternoon of tasting before returning along the coast.
This is a route that surprises people. San Diego is known for beaches, but the backcountry roads are world-class.
