Looking to ride up Locket Meadow. I've wanted to ride that section for years and haven't hit it yet by bike.

After the initial climb through the aspens, what are the trail riding options? Any maps or suggestions? Will need to end up at the Locket Meadow trail head, via loop or up and back (won't have a shuttle avail). Main goal is to max the ride time in the aspens. I sould have the whole day or upto 20 miles ... Ummm, aspens.
