The Napa Valley State Parks Association is volunteer led, nonprofit organization with the mission to raise funding and volunteers to support the three California State parks located in the beautiful Napa Valley: Bothe-Napa Valley State Park, the Bale Grist Mill State Historic Park, & Robert Louis Stevenson State Park. Funding raised by the Association is used for a wide assortment of maintenance and improvement projects, including replacing the great wheel on the Bale Grist Mill and sponsoring several summer outdoor education programs for Napa Valley youth.


Support our State parks by donating to the Napa Valley State Parks Association or attending a fundraiser. All proceeds go towards protecting our State Parks and increasing access for all. Funding is used for part improvements, purchasing needed supplies and supporting outdoor education program. Join us at one of our events and help us protect these amazing resources.


Robert Louis Stevenson State Park is 5,272 acres and contains stunning views of Napa, Sonoma and Lake Counties from the summit of the highest peak in the California Wine Country, Mount St. Helena.

Built in 1846, the Bale Grist Mill was a central piece of life during the early development of the Napa Valley as settlers came to have their grain ground into meal or flour and offers an authentic peek into Californian’s rural heritage.

Located in the beautiful Napa Valley, Bothe-Napa Valley State Park is the perfect getaway and community park. Hike amongst the redwoods, enjoy the creeks and scenery, camp out, picnic, or enjoy the spring fed swimming pool on a hot summer day!


In April 2012, Napa Open Space District (NOSD) along with Napa Valley State Parks Association, began operating Bothe-Napa Valley State Park and Bale Grist Mill State Historic Park as park partners.  Now, the NOSD operates Bothe-Napa Valley State Park, Bale Grist Mill State Historic Park and Robert Louis Stevenson State Park. While NVSPA provides financial support to help keep these parks running, both are not-for-profit entities supported by membership, donations, and fundraisers.

The California Department of Parks and Recreation provides for the health, inspiration and education of the people of California by helping to preserve the state’s extraordinary biological diversity, protecting its most valued natural and cultural resources, and creating opportunities for high-quality outdoor recreation.

NVSPA is proud to partner with 1% for the Planet, a global organization that exists to ensure our planet and future generations thrive. Click on the logo to view Napa Valley businesses that donate a portion of your purchase towards the NVSPA.
