Glen Canyon Park

A quiet city park great for hiking, dogwalking and nature viewing, containing a steep canyon situated amidst some residential neighborhoods. The park offers a rare glimpse into what the hilly landscape of San Francisco looked like before development. A small creek, Islais Creek, runs through the canyon and is one of the last free-flowing streams in the city.
