I’m with you on that Joe. I live on the East Coast but I’ve put well over 10K miles on rental cars in California over the past 15 years or so on business trips and vacations, mostly around SoCal. I did the Coast Highway drive from Monterrey to Cambria in ’99 when I went to the Historics and Pebble Beach. I agree, it’s a beautiful drive. Then I cut inland to the 5 freeway for a boring but quicker ride back down to LA.
Another favorite is CA State Route 2 a.k.a. the Angeles Crest Highway above the LA basin from La Canada to Wrightwood. Great road but there’s a lot of traffic on weekends, at least the first half of the drive.
Here’s one I’ve done while staying in Laguna Beach: Drive up the Coast Highway to the 55 freeway to Chapman Ave. East. That first part is a boring drive. Chapman turns into East Santiago Canyon Road. But first have lunch on the deck at Orange Hill Restaurant (http://www.theorangehillrestaurant.com) with a beautiful view of SoCal stretching out below. Then back on Chapman to Santiago Canyon Road and out into the twisties. It eventually loops around to El Toro Rd. and Trabuco Road right back to the Irvine commercial district and Mazda headquarters,where the original Cars and Coffee is held on Saturday mornings.
And the Ortega Highway from San Juan Capistrano to Lake Elsinore is a great drive now that the road work is done, but it too can be pretty crowded with sport bikes. However, leaving the Lake Elsinore area continuing east, if you cross the 15 and 215 freeways and pick up Highway 74 again in Hemet farm country, the drive up through the San Jacinto mountains and the San Bernadino National Forest to Idlewild and then back down the other side to Palm Desert in the Coachella Valley is spectacular, and there’s a lot less traffic even on weekends. The views and the switchbacks coming down to the desert floor in Palm Desert are unbelievable. If you plan to stay overnight there are a lot of good choices for lodging in the Coachella Valley before heading back to LA or Orange County. My wife and I have stayed a few times at the Casa Cody B&B in Palm Springs (http://www.casacodypalmsprings.com). Nice place stay, and there are plenty of good restaurants and bars in the area. I’m sure there are thousands of miles of little-known canyon roads in Southern California which the locals could tell us about, and I haven’t even mentioned my favorite roads in the San Diego area, but those are some of my favorites anyway.
