The Mill Valley/Sausalito Multiuse Pathway is a convenient connection between neighborhoods, schools, shopping, restaurants, and both a skate and dog park. The short dirt section at the north end is just a minor neighborhood connection and can easily be omitted if you are riding a bike or skating. Otherwise, the trail is entirely asphalt.
Overall, the trail gets a good mix of cyclists, walkers, joggers and skaters, so brush up on the rules of the trail before you begin. You can also access the trail by way of the ferry in Sausalito, making it possible to connect with other opportunities in San Francisco and Marin County. You could even rent a bike in San Francisco and take the ferry to Sausalito. This can make for a great day of exploring the region.
Although the trail is rather short, it and the nearby shoreline and art galleries are all worth exploring. The best feature of the trail is its views of the bay, where it passes through a scenic wetland marsh. You will see many species of birds here, including the marsh wren, brown pelican and maybe even a raptor, if you are lucky. Be sure to enjoy the houseboats of Sausalito when you cruise by. Parking is available at many of the adjoining business areas and at Sycamore Avenue. The trailhead has a public restroom.
The trail connects to the short Charles F. McGlashan Pathway at Coyote Creek, allowing trail users to enjoy pleasant views of the adjacent waterway. Most of the Mill Valley/Sausalito Multiuse Pathway is also a component of the San Francisco Bay Trail, and you will see signs advertising the trail as such. The system is a colossal effort to create a 500-mile multiuse trail encircling its namesake bay.
To reach the parking at Sycamore Avenue, take US 101 and exit at East Blithedale Avenue. Take East Blithedale Avenue west to Camino Alto and turn left (south). Take Camino Alto to Sycamore Avenue and turn left (east). Parking is available at the end of the road.
