Depending on who you ask, the American River Parkway is 23 miles long. It's made up of smaller parks like Discovery Park, River Bend Park, and Ancil Hoffman Park, and you can reach it via access points along U.S. Route 50. The Parkway makes swimming, wildlife-spotting, kayaking, and boating a joy, and you can jog or bike the neat Jedediah Smith Memorial Trail.
