Excellent trails. Bring drinking water when you visit the 1,833-acre Preserve; no drinking water is available. Please note that dogs must be on-leash at all times while visiting or hiking in Brushy Peak Regional Preserve to protect the area's fragile natural resources.
From I-580 in Livermore, exit north at Vasco Road and immediately turn right onto Northfront Road. After about .8 miles turn left onto Laughlin Road and proceed approximately two miles to the staging area at the end of Laughlin Road.
