Milagra Ridge Sharp Park Rd & College Dr, Pacifica, CA94044 Milagra Ridge, part of Golden Gate National Recreation Area, is known as an island habitat, meaning it is a unique…More ecosystem surrounded by human development. In fact, it is one of the last remaining habitats for the Mission Blue Butterfly and the San Bruno Elfin Butterfly, both federally endangered species. This 239-acre expanse of land, criss-crossed by well-maintained, mostly-paved trails, is a place of striking, almost surreal views. Fog from the Pacific Ocean hits the ridge and whips over its crest, slowing as it heads East amidst thick, low-lying brush and squat shrubs accented by vibrant wildflowers. On clear days, hikers can see westward for miles. Although the ridge teems with native wildlife, including coyotes, many species of birds and several kinds of plants, human development, off-trail use, and invasive non-native plant species continue to threaten the habitat. Milagra Ridge has therefore become the focus of local conservancy and stewardship efforts. Visit its Web site for more information and volunteer opportunities.
