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 changing weather conditions. During winter storm season high waters can make creek crossings hazardous, so plan your outing accordingly.  This page is updated as needed when trails are opened or closed, or when there is scheduled trail maintenance.
