Amphitheatre The San Francisco Recreation Department constructed a multi-purpose outdoor amphitheatre in the center of McLaren Park in 1970 and named it the McLaren Park Amphitheatre; In 2005, it was renamed the Jerry Garcia Amphitheater, after the member of the rock band Grateful Dead, who had grown up not far from the park, at 87 Harrington Street. At the time, it had a capacity of 2000 seats. La Grande Tank La Grande Tank is a prominent blue water tank on the western edge of the park, visible from Interstate 280 and the Excelsior neighborhood. It was built in 1956 and stands tall. During the seismic upgrades performed in 2006, money was set aside to improve what became the Philosopher's Way trail. Philosopher's Way A loop trail around the perimeter of the park called Philosopher's Way was dedicated on 5 January 2013. The trail, funded as a public art set-aside by the San Francisco Public Utilities Commission, offers views of Mount Diablo, Mount Tamalpais, Angel Island, and the Pacific Ocean on a clear day. It was co-designed by artists Peter Richards and Susan Schwatzenberg and features fourteen stone markers by mason George Gonzalez intended as "musing stations" to stimulate contemplation. Louis Sutter Playground Louis Sutter Playground, near McNab Lake in the northeastern corner of the park, was completed in 1965. Mansell Street Mansell Street was a four-lane divided road running east–west across McLaren Park, roughly dividing it into northern and southern halves. It was completed in 1963 and had been used as a shortcut to Candlestick Point and occasional street-racing dragstrip, but it was reconstructed as a two-lane road during the Mansell Street Corridor Improvement Project, a construction job lasting one year. One side of the road was rebuilt as a dedicated pedestrian and bicycle path, and crosswalks with bright flashing beacons were added to major intersections, allowing foot traffic between the north and south halves of the park. Mansell Street through McLaren Park is significantly wider than the city streets it connects with on the western and eastern edges of the park. It was designed and constructed as a segment of the planned Crosstown Freeway which never came to fruition in the wake of the San Francisco Freeway Revolts. Mansfield-Burrows Playground Mansfield-Burrows Playground, near La Grande Tank in the northwestern corner of the park, was added in 1978.
