The dog-friendly Ecology Trail at the Presidio is a 1.4 mile pathway in San Francisco with distinctive habitats from shaded forests to serpentine grasslands. Dogs are welcome on this trail as long as they are on leash.
A variety of California native plants can be seen here, from the endangered Presidio Clarkia, which supports pink blooms in spring, to majestic oaks and redwood trees. A spur trail connects to El Polín Spring, an “outdoor classroom” known for history, bird-watching, and a terrific new picnic area.
The trail is hiker-only in the upper portions, but bicycles are allowed below.
