Westwood Hills Park is a heavily-wooded Napa City park. The park provides three miles of trails through beautiful groves of oak trees and grassy meadows, and affords expansive views of the city. The park includes benches and picnic tables near the parking lot and along the trails.
The non-profit Napa Valley Naturalists operate the Carolyn Parr Nature Museum near the parking lot at the park. The Center's exhibits depict the plants and animals found in Napa County's five different habitats. There's also a children's nature library, "hands-on" corner of skins, nests and bones, and an extensive nature reference library. The Center is open year-round on Saturdays and Sundays from 1-4 pm. During the summer it is open Tuesday-Sunday at the same hours.
