Many areas of Midpen preserves are open to the public daily, free of charge, providing an extensive trail network for low-impact recreation. Our programming connects people to nature through enriched experiences including environmental interpretation, docent-led activities and volunteer opportunities.
Preserves are open a half-hour before sunrise until a half-hour after sunset, with sunrise and sunset defined by the US Naval Observatory for coordinates set to Midpen’s Administrative Office in Los Altos, CA. Learn more here.

Trail Closures
Trail conditions can vary depending on the time of year, the impact of rain and storms, construction and maintenance and other occurrences. Please be aware that trail closures may change from day to day without notice, based on current and predicted weather conditions. During winter storm season high waters can make creek crossings hazardous, so plan your outing accordingly.
