Coyote Hills Regional Park was dedicated to public use in 1967. Comprised of nearly 980 acres of marshland and rolling grassland covered hills, this busy park is located along the eastern shore of San Francisco Bay, northwest of the cities of Fremont and Newark. The most popular visitor activities by far are bicycling, walking, bird watching, jogging, nature exploration, and picnicking. Well used every season of the year, spring, summer, and fall tend to be the most popular. But the park's winter beauty is wonderful to behold.
I really enjoy biking at Coyote Hills. I created this trail to share the big loop that includes the shoreline trail to the Dumbarton Bridge for those who like the challenge of a little extra distance. You can do a shorter version by taking the "no name" trail back. I added a track that shows this, it's about 9 miles. Someone should really name that trail. :)
There is no shade at Coyote Hills and you will get some reflection from the water, so be sure to bring protection. Also, do not bike on shoreline trail after a recent precipitation as you will get bogged down in the track along the slough. It's like biking through cement when it's wet.
There is moderate traffic along the trail until you reach the western portion. The section between Alameda Creek Trail and the Dumbarton Bridge has very little traffic. This morning I didn't see anyone, just a bunch of geese. I like getting off the beaten path and this is a good place to do that.
If you want to add some distance, you will pass the entrance to bike across the Dumbarton Bridge along Marshlands Rd. And you can also connect to the Newark Slough trail.
I averaged 15 mph throughout the trail. Usually you will get a tail wind on the way back to the parking area on Paseo Padre, which makes the last couple of miles easy.
