Thanks for the info. guys. Is Mt. Langely open now? Someone told me that it's closed due to the big horn sheep. Starting from horeshoe medows, how long would it take us to go up and down and back to horseshoe medows? Is there good camping there ? Thanks in advance.
It's not currently closed. There's good camping both at the trailhead, and along the trail if you choose to do it as an overnight. As to how long it will take - that's up to you, but can tell you it's about 18-20 miles, depending upon which route you take. It can be done as a long dayhike.
I did it last week via (Old) Army Pass - no snow on any part of the route.
There are recent threads on Langley - would suggest you do a search if you plan to do it.
