The best drives aren't just about what you're driving, they're about what you see, feel, and soak in along the way. S6 South Grade climbs Palomar Mountain through tight switchbacks that reward every driver who commits to the route. At the top, the Palomar Observatory has been watching the stars since 1948, earning S6 and S7 their nickname: the Highway to the Stars. But the drive doesn't end at the summit. The descent through S7 into Mesa Grande opens onto a quiet rural plateau that most visitors never bother to reach. This is the reward for drivers who complete the full loop. The Palomar Mountain design captures the full experience: the observatory dome rising against a constellation-filled sky, a bobcat holding its ground in the mountains, dual S7 and S6 San Diego County shields marking the way, a Jeffrey Pine rooted in the mountain's slopes, and the Mesa Grande sign pointing toward the payoff at the bottom.

Perfect for mountain drivers, stargazers behind the wheel, motorcycle riders, and anyone who knows that the best part of Palomar isn't the summit, but it's what comes after.
