Lake Oroville, the state’s second-largest reservoir after Shasta, is the county’s biggest summertime recreation magnet, offering floating campsites and many other opportunities for summertime doggie fun; just be aware that beach and turf areas are off limits to canines. When the lake is full, it comes to within a quarter-mile of Feather Falls, a three-tiered, 410-foot cascade on the Fall River that is gushing this year due to the massive snowpack in the Sierra. The nine-mile Feather Falls Loop Trail is dog-friendly and leads to a railed observation platform, but check before you go as the lower loop was closed at this writing due to footbridge damage, meaning you may have to backtrack rather than complete the loop.
