Rush Creek Trail is really just a dusty old fire road that skirts a tidal marsh. It’s flat and at about 4 miles to the end and back is popular for beginning cyclists, joggers, and families out for a stroll with their dogs. Because of it's open vistas and wildlife; It's also great for photographers.
In season, usually fall and winter Rush Creek Marsh is a prime location for viewing shore birds including Great Blue Herons, egrets, pelicans, and ducks and wading birds of all types. Riding the thermals above Pinheiro Ridge, which is on your right on the outbound leg of the walk, there will usually be a red-tailed hawk or two, possibly a red-shouldered hawk and, almost certainly, a handful of turkey vultures.
Across Rush Creek Marsh, on your left, are nice views of Mt. Burdell, which at 1,500 feet is the highest peak in Northern Marin. When the tide is in and the wind is light Mt. Burdell will be reflected in the marsh waters and is especially dramatic during sunset with the sun setting directly behind the mountain.. In spring there are plenty wildflowers.
This is not a park; there aren’t picnic tables or restrooms or other amenities. You’ll have to carry everything you need and pack out what you don’t. Rush Creek is located just north of Novato, California, off of Atherton Avenue, about 30 miles north of San Francisco.
