Hike Details: Elevation - 550' - 700' Location - Auburn State Recreation Area Parking - We parked in the lot (fee required) right at the trailhead on the left side of Highway 49 after crossing the bridge. There's often parking along the road for free if you get there early. Mileage - 5+ miles Hiking time - 2 hours Route - We just followed the trail along the river, with a little side hike up to a rock climbing area, than continued back along the river for a couple of miles, and returned back the same way. Good morning, beautiful American River! Mountain Quarries Mine entrance -- apparently there's a little lake inside with a boat still tied up. Inside the little cliff/quarry rock climbing area Rocking our Heidi Run shirts And rocking the selfie stick :)
