2 years ago while fishing the Cheakamus around Fergies Lodge (first bridge) I saw a small black bear on a number of occasions. I believe Rod "ran into" (lol) a deer or 2 a few miles up Squamish Main after the Paradise Valley turnoff. I have even seen a black bear at the side of the road by Furry Creek. If you go all the way up Squamish Main and take the Elaho Main you might even see some Goats or Sheep, and maybe even a Grizz. I have fished a side channel of the Squamish by the Ashlu a few times and have seen Grizz tracks, but never actually ran into one. A CO did tell me that they have been reported as far down as the mouth of the Cheak where it dumps into the Squamish.
I have also seen deer and black bear across the Fraser from Laidlaw, I think they were on an island, but they had to get there from somewhere.
If it were me, Squamish would be the place to go. There should be some Bald Eagles around Brackendale, and the scenery along Squamish Main is friggin awesome.
Also take them for a quick walk up to Shannon Falls...I have taken out of towners up there and they loved it...we jumped the fence and scrambled up about halfway...good pics.
Have fun...
