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.

Keeping our trails beautiful and dog-friendly is crucial to ensure everyone enjoys the great outdoors. Some people want to ban dogs from public spaces, but we believe dogs are essential members of our community. They bring joy, companionship, and energy to our hikes. To keep our trails open to our furry friends, we must be responsible. Pick up after your dog, keep them on a leash where required, and respect other trail users. By doing our part, we can ensure that our beloved pups remain welcome on all trails, allowing your pack to continue exploring and enjoying nature together.
