This is just one section of a very long trail. It's an 'ok' trail that affords you lots of high-country access (Sparks Lake, Todd Lake, Flagline trail). It's a great trail, but it can be soft and horse trodden in some places, mostly near Todd Horse Camp (surprising!).
The section from Todd Horse Camp to ~1/2 mile past Flagline access is a pretty decent uphill, and the views are well worth it.
