The health and safety of our community, preserve visitors, volunteers and employees are Midpen’s top priority. We are following county health orders as we work 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. 

Please be understanding, we are all in this together. Be responsible for your own behavior.

We’re grateful these public lands exist and that so many of you support efforts to protect, preserve, maintain and restore our natural and working lands for the benefit and enjoyment of our broader community.
