Highway 49 is the main route to a little clothing-optional beach on the north side of the American River, in Auburn.
Temperatures bake here in the summer, making the riverbank a tempting spot to disrobe.
Rangers have reportedly told visitors they won't issue citations for nude sunbathing unless they receive complaints. But they have also advised users not to stand or walk around without bathing suits. Head east on Elm, then turn left onto High Street, which is at the first signal. Stay on High, which becomes Route 49, for about two miles, until it widens. From the parking area, take the trail down toward the river until it comes to a wider dirt road.
