My suggestion? Don't do it as a dayhike! LOL
I'll send you a PM, but will say I hope you are good at route-finding. The "trail" from the main trail up to Kerlee Lake would have been almost impossible to find had I not been there with someone else that knew where to find it. And steep!
Overall, though, it is a beautiful area and we didn't see anyone after we broke off the Tin Cup trail. If you're going to be there a couple of days, you could also try climbing the Como Peaks and the Lonesome Bach, they are actually right above Kerlee Lake.
