The 12-mile long multi-use Alameda Creek Regional Trail hugs both banks of Alameda Creek from the mouth of Niles Canyon in the east, to San Francisco Bay at its western end.
The south bank trail provides access to Coyote Hills Regional Park on the Bay. The south bank trail is designated for use by pedestrians and cyclists (no motor vehicles are allowed), and the trail along the north bank is also available for use by horseback riders.
The Alameda Creek watershed covers 633 square miles, and is the largest tributary to southern San Francisco Bay. The creek once supported salmon and steelhead trout; a very small remnant population of steelhead remains. There are currently a number of efforts underway to help restore native fish to the creek and improve migration of these and other migratory fish into the Alameda Creek watershed.The trail is also good spot for observing birds in an otherwise developed landscape.
The trail is accessible from several thoroughfares in the Fremont, Union City and Newark areas, and is only a few blocks from the Union City and Fremont BART stations.
