Friends of the Napa Open Space District Friends of the Napa Open Space District is dedicated to sharing the parks and trails of Napa County that are managed by the Napa Open Space District.

In November of 2006 Napa County voters approved Measure I establishing the Napa County Regional Park and Open Space District. The District is authorized to plan, improve and operate a system of public parks, trails, outdoor recreational facilities, and outdoor science and conservation education programs, as well as to protect and preserve natural areas, wildlife habitat and other open space resources. Its jurisdiction includes all of Napa County. The District is governed by a Board of Directors whose members are directly elected by the public in each of five wards. Ward boundaries coincide with the County’s Board of Supervisors’ districts. Funding and staffing for the District currently comes from the County of Napa, at the level determined by the County Board of Supervisors. The District is also empowered to obtain grants, accept gifts and collect fees for services provided. Subject to voter approval, the District is authorized to raise revenues through some types of property assessments and taxes. The District has no power to regulate private land use, is subject to all applicable city and county regulations, and may only acquire property from willing sellers.

The annual Ridge Trail Service Day is coming up soon and we still have a couple of spots available!

For 16 years, the Ridge Trail has hosted one day in November where volunteers can join in one of multiple sites along the Ridge Trail route. We're always excited to host a Napa site and get some of our local volunteers together with traveling Ridge Trail fans for the day.

This year, the NOSD project will be at Bothe-Napa Valley State Park, where we'll get in to a more remote section of the Ridge Trail and work on trail improvements. Bring your work gloves and hiking boots, and get ready for some fun!

Register on the Ridge Trail website or email us at [email protected] for details.

Today, NOSD recognizes Indigenous Peoples' Day. This is an opportunity to recognize and reflect on the history and culture of our nation's first inhabitants.

The Napa County Regional Park and Open Space District respectfully acknowledges that the lands we manage occupy the ancestral unceded land of the Micewal, Me-Wuk, and Wintun peoples, who have stewarded this land throughout the generations and continue to have a sacred connection to these places.

It’s been a bit warm lately, but we’re still finding times (like early morning) to !

You can help support NOSD’s continuing work to grow and maintain parks and trails across the county with donations to the ReLeaf Napa Fund. We’re glad to be able to keep most of our parks and trails free-free at the trailhead for everyone’s enjoyment, and everyone’s donations and ReLeaf Napa memberships help us do just that.

If you’re already a regular donor, thanks for all the support! If you haven’t donated lately, we have donation boxes at Moore Creek Park and Oat Hill Mine Trail, or the online donation box at NapaOutdoors.org/ReLeafNapa

We’re getting close to the end of the year already (somehow), but there are still a couple of our guided 3rd Saturday Hikes coming up! Look for RSVP details for these in our monthly newsletter and posted to the website a few eeks in advance of each date.

The 3rd Saturday Hike series happens on the 3rd Saturday of each month, naturally. These are free guided group hikes and we switch up the themes for each month every year when we assemble the calendar. Find one that suits your interests, or learn about something new that you’d never even considered before!
You can get details for each monthly hike on the “3rd Saturday Hike” page of our website (link in bio).

Can’t make it to Old Mill Days this weekend but interested in the history and function of this heritage building? We put together a series of videos in 2021 that serve as virtual tours of the Bale Grist Mill.

You can check out the full playlist on our Youtube channel (@ NapaOpenSpaceDistrict).

Of course, we think it’s much much better to see the mill in person, open weekends for tours – and of course this Sat/Sun for Old Mill Days! You can get details on the “Events Calendar” page of our website (link in bio).

We know we’ve been posting a lot of golden eagle photos lately, but these are too good not to share!

The goldens at Suscol Headwaters Park seem to love the cameras lately, could be that they’re appreciating their newfound fame as nature models.

Raptors of various kinds inhabit the ridges along Suscol Headwaters Park and can be seen most days gliding and soaring on the updrafts that shoot up the ridgeline. If you’re into bird watching, this is a great spot to enjoy the view and watch them doing their thing.

Special thanks to anonymous NOSD staffer that's gotten so good at capturing these (usually) camera-shy birds.

Old Mill Days is coming up this weekend & we’d love your help!

We have a small army of volunteers that help put on this event each year and help folks step back in time and experience what life was like in the “old days” at the Bale Grist Mill. We’d love to have a few more volunteers to help out this weekend.

If you’re available to help, send us a note at [email protected]. The event runs from 10am-2pm and we have different roles and shifts available.
