Beyond Glen Canyon Park's recreation center, ball field, and tennis courts lies a large urban canyon that has incredible spring wildflower displays, dramatic rock (chert) formations, and Islais Creek, one of the few remaining free-flowing creeks in San Francisco. This 60 acres of wilderness, formerly referred to as the San Miguel Hills, not only provides critical habitat for a wide array of wildlife, but serves as a relaxing sanctuary from the city's urban bustle. An extensive network of hiking trails leads through a variety of habitats, from the lush creekside vegetation to the rocky grass- and scrublands of the canyon's steep eastern slope, where a profusion of wildflowers blooms each spring.
