Yep. Left Hand can be done solo if you stay on Trail Marker 286. You could possibly even do the "Squeeze," if it isn't too wet and you don't mind stacking a few rocks. The right hand side, line, is the way to do that obstacle. Turning around at the "Squeeze," isn't a big deal, but you will run in to traffic going back down, and the trail is barely wider than one truck in most places.
