Flatten the Covid-19 curve at parks by taking soap and hand sanitizer, maintaining social distance of 6 feet or more, stay home if you're sick.

Updated Sunday, March 30, 2020

The health and safety of our community, preserve visitors, volunteers and employees are Midpen’s top priority. We are working hard to keep trails and preserves open to provide a safe opportunity for people to be in nature for mental, as well as physical, health during this public health emergency.


Most Midpen preserves are open at this time. However, if visitors do not maintain safe social distancing—stay 6 feet apart from people you do not live with—we may have to close our preserves. Please follow these simple guidelines to reduce crowding in Midpen preserves.

  • Do not hold social gatherings at parks or anywhere.
  • Share the trail and yield to others to maintain a safe distance.
  • Do not park in a crowded parking lot or use a crowded trail.
  • Leave no trace: pack out what you pack in. Most Midpen preserves do not have garbage cans and collection is limited where we do..
  • Look for nearby nature to enjoy, look for the hidden nature in your own neighborhood.

Know before you go

  • Restrooms and drinking fountains are closed; plan ahead before leaving home.
  • Windy Hill Preserve is closed. Other areas receiving high use may be closed without notice. Please check the trail conditions and preserve pages before heading out.
  • Certain crowded narrow trails at Rancho San Antonio will be restricted to one-way traffic beginning Monday, March 30.
  • Parking restrictions around popular preserves have been posted for Highway 35 around Purisima Creek Preserve, Alpine Road around Russian Ridge, on Cristo Rey Drive near Rancho San Antonio, and around Windy Hill in Portola Valley.
  • Paper maps are no longer available at preserves. Please download a map before leaving home or snap a photo of the signboard map before you hike.
  • Group gathering areas are closed including Deer Hollow Farm, Daniels Nature Center, Black Mountain Backpack Camp and Picchetti Winery and picnic area.
  • Group activities are suspended including docent-led hikes, volunteer projects and special use permits. 
  • Midpen has closed our main office at 330 Distel Circle in Los Altos in compliance with county health official orders to shelter at home. Staff are working from home and remain available via telephone or voicemail (650-691-1200) and email (info@openspace.org or individual emails) during regular business hours of 8:30 a.m. to 5 p.m., Monday through Friday.

A letter to the public from the Midpen Board of Directors

As we all face these extraordinary times in response to the COVID-19 order, the Board wants to thank everyone in the Midpen family for their efforts and successes in keeping most Midpen lands and trails open so people can get exercise, get out of their apartment or house, breathe in the fresh air, and have a respite in nature. We are proud of our staff for acting creatively and proactively so we can continue to serve the public in this way, while also continuing our constant work of managing our open spaces to protect our vital natural resources and enhance our overall regional resilience within our spectacular Bay Area home.

More than ever, we need “room to breathe.” Thank you for the support you have all shown Midpeninsula Regional Open Space District over the years, and please join us in thanking our staff for their dedication and continued work.

    Good health to you all,

    Ana Ruiz, General Manager            Karen Holman, Board President
