The hills were originally named 'Los Pechos de la Chola' (Breasts of the Indian Maiden) by early Spanish settlers.
The two peaks are individually named Eureka Peak and Noe Peak.
The area is home to the Mission Blue butterfly, an endangered species protected under local conservation efforts.
The peaks were historically used by the Ohlone people for lookout and ceremonial purposes.
The topography acts as a primary wind tunnel for the city's famous fog.
The park contains the Twin Peaks Tunnel, which carries Muni Metro light rail trains underneath the hills.
Twin Peaks serves as a high-altitude vantage point in San Francisco, offering a 360-degree panorama of the Bay Area from an elevation of approximately 922 feet. The park consists of two adjacent hills, Eureka and Noe, which remain some of the few remaining unbuilt hills in the city. A paved road leads to a central parking plaza, while pedestrian trails connect to the summits. The site provides unobstructed views of the Golden Gate Bridge, Mount Tamalpais, and the Financial District skyline. The park is managed by the San Francisco Recreation and Park Department and maintains a natural, open-grassland habitat. Fog frequently rolls over the peaks, creating a distinct microclimate separate from the city below.
The main North Peak lookout parking lot, specifically the concrete wall facing the downtown skyline.
Dress in layers regardless of the sunny forecast, as the wind chill at the summit is significant.
Visit during the 'golden hour' for clear visibility before the evening fog settles in.
Secure all belongings inside your vehicle out of sight, as this is a high-traffic area for vehicle break-ins.
Do not leave any bags, electronics, or personal items visible inside parked vehicles.
Stay on marked trails to protect the fragile coastal scrub ecosystem.
