Sunnylands Center & Gardens
37977 Bob Hope Dr., Rancho Mirage
The fact that Sunnylands serves as the Camp David of the West Coast kind of does this stunning estate a disservice: And while it's still frequented by many presidents and politicians, it's open to the public. Designed for the Annenbergs by A. Quincy Jones in the '60s, it is one of the more stunning examples of mid-century architecture, and it's situated on meticulously manicured grounds. Book well in advance for tours, though you can always stop by to see the permanent exhibition, which offers a great survey on some of the home's big moments over time.
