All other trails remain open year round. Seasonal trails in the Pearson-Arastradero Preserve close any time rainfall exceeds one-half inch over 48 hours or 1 inch in seven days*. Trails are then evaluated for reopening after 48 hours of no rain and reopened only when dry.

For daily trail condition updates, please check the bulletin board in the preserve parking lot, or call 650-329-2423 and ask for the latest trail conditions in the Pearson-Arastradero Preserve.

*Rainfall is measured in Foothills Park, near the headwaters of Arastradero Creek.
