2 Best Sights in Rancho Mirage, Palm Springs and the Desert Resorts

Despite being an active retreat venue, the stunning 200-acre winter home of the late Ambassadors Walter and Leonore Annenberg, which has welcomed eight presidents and first ladies, royalty, numerous world leaders, and countless celebrities, is open to the public for free. You could easily spend a day taking a self-guided audio tour of 9 acres of art-filled grounds; viewing art exhibits; watching a film about the estate and the desert diplomacy that has happened here; grabbing a bite in the café; and participating in wellness activities, classes, or other programs. For an insightful peek inside the 25,000-square-foot mid-century marvel, book a 90-minute Historic House Tour. Guided estate (shuttle and walking options) and birding tours are also available.

Get a good look the night sky at this city-owned observatory next to the public library. The complex includes five high-powered telescopes—four on the deck and a main telescope in the 360-degree observatory dome that's designed to look like a comet. There is a 3 pm tour on weekdays, and stargazing parties are usually scheduled two times a week. Astronomy lectures are also held regularly.
