Hamilton Park, 1210 S Eliseo Dr, Greenbrae, CA 94904, US

Within walking distance of downtown Mill Valley, Old Mill Park is a popular spot for local families and historians alike. The name refers to Reed's Mill, one of the first structures built by European immigrants in southern Marin County. The original mill was built in the 1830s and replaced by an exact replica in 1990. The redwoods in the park aren't as grandiose as those in nearby Muir Woods but have a calming effect on everyone who comes to play, picnic, or sit.Parking and public transportation at Old Mill ParkStreet parking only, as the Park is in a neighborhood near the Mill Valley Library and across the street from Old Mill School. Parking is mostly free (metered closer to downtown) but comparatively hard to come by as the area is well-traveled. Busses run to downtown Mill Valley regularly and from there it's a short walk to the Park. It's almost better to make the Park a destination on a bike ride or hike to avoid the parking hassle.Best and worst time go to Old Mill ParkWith Old Mill Elementary school right across the street, avoid school drop-off and pick-up times if at all possible. Weekday early mornings and late afternoons, before and after the schoolkids are gone, are the quietest times to go. Since it is rather popular there will always be some sort of crowd but it's usually easy to find a little place of your own. The Mill Valley Fall Arts Festival is held on the grounds every year.Admission to Old Mill ParkNo admission fees to Old Mill Park. Open hours are from dawn till dusk. No camping allowed.
