Managed a smaller version of this loop as a day trip. Center Park TH up ridge to 11,842 through Stone BM, then I dropped down past Doll Lake to the north end of Five Points Lake and took the trail out. GPS read 26.6 miles and 5000 total vertical gain. Took me 11 hrs.
Thanks to ZeeJay for such an awesome route posting! Outstanding views both east and west from the ridge. Lots of elk at treeline and mountain goats higher up.
