If you live in Sacramento or anywhere near the Interstate 80 corridor through the Sierra Nevada foothills, the five-mile round trip to 30-foot Hidden Falls
should be on your "must do" excursion list. The falls, whose furious roar can be heard long before the wall of white water can be seen, are the centerpiece of 221-acre Hidden Falls Regional Park between Auburn and Lincoln in Placer County. Dogs are welcome, but with a caveat: Because the trail is shared by hikers, mountain bikers and equestrians, it's important to keep Rover leashed and to observe standard trail etiquette
. The rule of thumb: cyclists yield to horses and hikers, while hikers yield to equestrians. If you see or hear a horse approaching, step off the trail on the low side to let the riders pass. Never, ever approach a horse unannounced from the rear.
