Agua Caliente Hill Trail #46 in Coronado State Park. 9.25 miles (round trip) of a relatively strenuous trail (lots of climbing). Too hot for summer, but perfect for a winter day. Beautiful views of the city. Although Cat Track Tank at 1.6 miles sometimes has water, it's best to bring a good supply for you and your pup. Coming from out of town?
