Way out of the way for you, probably, but accessible by vehicle off the Cassiar Highway - Hyder, northeast of Ketchikan. The border is open coming into the US - no customs station - but not so going back into Canada. Their customs is about 300 ft past the border.
You can also fly in from KTN via Misty Fjords Air.
There is a
bear viewing area about a mile north of town on Salmon River Road. I was there last fall as part of a work trip (the road is being paved from the border to the bear viewing area). It can really be a spectacle but there have to be fish in the stream for the bears to show up. They have both black and grizzly there.
