New guy -- trip planning for Yukon Terr.

Wanted to see if I could get any advice from some of the more experienced hands on the boards…New to the whole packrafting/trekking thing, and while I’m still trying to read up on as much as I can – here and elsewhere – decided I want to try the Carcross-Whitehorse trip below.

Just sounds like a helluva trip! But wondering though when would be the best time of the year to do this? Again, this would be my 1st packrafting/trekking trip, so any advice is much appreciated. Thanks.

Did I post this ? in the wrong area? If so, I can delete/repost in the correct forum. Really need some advice on this trip. Thanks

July would be ideal.
