In the middle of San Francisco Bay sits Angel Island State Park, offering spectacular views of the San Francisco skyline, the Marin Headlands and Mount Tamalpais. The island is circled by foot trails and fire roads. Visitors can climb to the 781-foot high summit of Mount Caroline Livermore. Bicycles can be brought to the island on the ferry and used on the island's main roads. Beaches are at Quarry Point and Ayala Cove on the island. Perle's Beach, although more exposed to wind and weather, offers a spectacular view and opportunities for walking and beachcombing.

The island is also alive with history. 3,000 years ago the island was a fishing and hunting site for Coastal Miwok Indians. It was later a haven for Spanish explorer Juan de Ayala, a cattle ranch, and a U.S. Army post. From 1910 to 1940, the island processed thousands of immigrants. During World War II, Japanese, and German POWs were held on the island, which was also used as a jumping-off point for American soldiers returning from the Pacific. In the '50s and '60s, the island was home to a Nike missile base. Today, there are two active Coast Guard stations on the island. Access to the Island is by Public Ferry or private boat.
