Part of the Fremont section of the San Francisco Bay Trail (SFBT) runs inland along city streets through neighborhoods and industrial areas without much of a view of the bay. The exception is a small segment along Fremont Boulevard in FremontCoyote Creek Lagoon.
The 4-mile trail is wide and flat, making for a good family ride or walk. The marshes hum with birdlife and you can fish along Coyote Creek just before it enters the lagoon.
The Coyote Hills and Alameda Creek sections of the SFBT incorporates the Don Edwards San Francisco Bay National Wildlife Refuge, 25,902 acres around the South Bay from Redwood City to Fremont. It's the largest urban wildlife refuge in the country, and your ride or walk through the trails here will offer plenty of bird watching. You can also fish from Dumbarton pier and stop by the visitor center in Freemont to learn more.
Within the refuge, take the Tidelands Trail, beginning from the visitor center and climbing to the top of the hill. An overlook offers spectacular views. The Coyote Hills Trails reach only 291 feet at Red Hill Summit but provide panoramic views of the Bay Area. The steep Red Hill Trail runs down the spine of the hills and intersects the Nike, Soaproot and Glider Hill trails.
The Alameda Creek Trail allows recreational access to the levees along the creek and flood control channel. The trail runs on both sides of the creek and the Alameda Creek Flood Control Channel, from Niles Canyon to San Francisco Bay. The trail on each side of Alameda Creek is about 12 miles long. The south-side trail is paved, while the north-side trail is mostly unpaved and favored by equestrians. Both sides traverse densely-populated areas and are heavily used.
