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 seasonal trail closures may change from day to day without notice, based on changing weather conditions. During winter storm season high waters can make creek crossings hazardous, so plan your outing accordingly.

There will be extensive trail work and closures during 2015 on the remaining moderate and high priority Watershed Protection Program road and trail projects within the El Corte de Madera Creek Open Space Preserve.  This work is planned to occur between May and October, 2015.  It will result in some closures and or delays when using trails within the preserve.  Please see the Trail Work and Closures Map for the dates of anticipated closures.  When possible trails will be kept open but do not count on being able to use any of the trails during the dates they are anticipated to be closed.
