Alston Park covers 157 acres in the unobstructed rolling hills of northwest Napa. The open-space park, owned by the city of Napa, was made public in 1991. Alston Park has three miles of meandering trails that are open to equestrians, mountain bikers, hikers, and dog walkers. Redwood Creek, a tributary of the Napa River, forms the park’s western boundary. This hike climbs to the upper area known as Canine Commons, a popular off-leash dog area. The trail circles the oak-dotted grassland through an old plum orchard on the south and wildflower- covered meadows with oak and madrone groves to the north. The hike detours into the shaded canyon by Redwood Creek and leads to picnic areas and overlooks, offering sweeping vistas of the city of Napa and Napa Valley.
