I was up in the Yukon a couple of years ago. We didn't do a lot of fishing, lots of touring around. I did find the people at the information centers really helpful. The visitor center in Haines Junction is really nice. From Haines we went south and fished Kathleen river. Caught a rainbow and some grayling. Good sizes there. We then went to Jarvis river west of Haines Junction. It is smaller but full of grayling. My daughter had a blast there where she named her little mepps the grayling slayer. She couldn't keep them off. Beautiful up there!
