48 SMITH RIVER Crescent City The largest undammed river in California, the Smith River fl ows 25 winding miles from the Klamath Mountains to the Pacifi c Ocean. Its sparkling waters attract anglers chasing the autumn chinook salmon run or winter-to-spring steelhead run, and kayakers seeking whitewater challenges. In summer, the river turns lazy, and swimmers hit the banks for tubing and picnicking. Lay your towel on beaches at Mary Adams Peacock Bridge, Myrtle Beach, or Panther Flat Picnic Area off Highway 199. ,
