Irish Hills Natural Reserve is a geographically discrete 720-acre riding area with 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.

Lopez Lake

The predominately sandy trails of Lopez Lake wind around the Wittenberg Arm of the lake. The gentle roller coaster single-track curves through the campground, emerging to skirt the water’s edge, and finally climbs to the top of the ridge for a panoramic view west to the Pacific Ocean.
