Need advise on 5 days in the Rae Lakes, 60 Lakes Basin, Lake Relfection area with daughter.

I am supposing you mean Deerhorn Saddle? Secor has very little to say about it other than it's class 2. I haven't been over it myself. It appears to be a steep scree slog on Google Earth. Is it worth it? I suppose that depends on how much you love scree.

Lake Reflection is gorgeous, so are all the lakes near Rae Lakes. That's a hard call to make. If you want something less athletic the second option sounds nice. If you're fishing, 60 Lakes is fishless.

Sixty Lakes Basin to me was more about seeing faint, old trail. Not much there, might be pretty early in the season with green grass and flowers. I found an old trail in there, so that was neat. Have to consult a map on which lake I left from to get into the basin. I had hiked up from Woods Crossing that AM, maybe the second lake up from the Crossing, headed south, you may have to scout a tiny bit, or go off of the contours on your map for the easy way in, there was a use trail, although some rock had rolled onto the trail. Fish and eat all you can at the Rae Lakes, they have too many fish.

I've read a few trip reports which included traversing Deerhorn Saddle, a few by very experienced folks, none have come anywhere close to a recommendation…
