Circling the Bay: A Day Hiking Angel Island State Park
Ferries, coastal trails, and Bay-spanning views on San Francisco’s historic island escape
The ferry noses past Alcatraz and into the bright bite of wind that rules San Francisco Bay. Gulls heckle the bow, the skyline stacks itself like a story you can’t quite finish, and Angel Island rises ahead—green shoulders, bluff edges, the hint of a trail curling into the trees. The current pushes, the tide answers, and for a few minutes the city slips away as if it were only a rumor. When the boat glides into Ayala Cove, the island feels closer and older than you expect, a self-contained world ringed by water and history.
Trail Wisdom
Catch the First Ferry
Arrive early for the morning boat to beat crowds and take advantage of calmer winds and softer light on the ridges.
Choose Your Loop Wisely
For an easier day, hike the 5.5-mile Perimeter Road; for a more rewarding climb, combine the North Ridge and Sunset Trail for a 6–7-mile figure-eight.
Mind the Wind and Fog
Bring a windproof layer year-round; summer can be the windiest with fog swirling near the Golden Gate.
Poison Oak Awareness
Some singletrack edges are lined with poison oak—wear long sleeves or keep a wide berth, especially in spring.

Conservation Note
Stay on established trails to protect sensitive coastal scrub and historic sites; pack out all trash and respect building closures and restoration areas.
From 1910 to 1940, the Angel Island Immigration Station processed and detained immigrants—many from Asia—earning the site the nickname ‘Ellis Island of the West.’
