we were just there a couple of days ago. Saw one black bear, one big grizzly. ranger said 7:30-8:30 pm is the best time, but the bears are pretty full. dead salmon everywhere.
what was BETTER was Hanna creek., just south on the Cassier. apparently 2 young grizzlies hang out there regularly. We watched them fish for salmon for about 15 minutes.
Milepost tells you where Hanna Creek is.
here's my blogpost about it:
