We did this trip towards the end of September and were rewarded with clear skies,golden larches and spectacular views. The ride on the shuttle bus eliminates the real hard work of getting out of the valley and drops you high in the alpine region.The only thing I would add to other reviews though, is that once there, the hiking is not completely effortless. By Rockies standards it isn't difficult, but by the time you have climbed up from the main ski lodge (where the shuttle bus drops you), descended to the lakes on the other side, maybe climbed to the lookout, and then completed the circuit, the amount of uphill hiking must be not far short of 1500 feet.
We got the impression that some people on our shuttle bus thought they would get the fantastic views as soon as they got off the bus. Certainly quite a few of them didn't tackle the first quite steep climb out of the ski lodge bowl, so they didn't get the views.
