Anna's hummingbird Will Elder/National Park Service
A great hike for nature lovers that connects Arguello Gate to the Presidio's Main Post. The Ecology Trail is multi-use for pedestrians and cyclists, and connects to the Bay Area Ridge and Mountain Lake Trails. Check out El Polin Spring, a great site for spotting hummingbirds, and keep your eyes peeled for wildflowers like the native Presidio clarkia.
