Irish Hills

Irish Hills Natural Reserve is a geographically discrete 720-acre riding area, yet it contains over 8 miles of trails. Many loops are possible on mostly single-track trails. The rocky, serpentine landscape contains chaparral, oak, grasslands, and riparian habitats. The area’s wandering distribution of double-track attests to its mining history and also serves as a link between the single track sections. Dogs welcome on leash.
