We stayed in Denali in August (last year) and saw tons of bears because they were out feeding for their winter sleep. The bus in front of us reported a mamma grizzly with her 2 two year old cubs in the road. Mama grizzly was upset with the bus being in her territory and slapped the bus door with her paw, nearly breaking the door, thrilling and scaring the passengers. By the time we got to that location, the bears had moved off the road onto the hillside to continue feeding. Must have been the time of year we visited Denali but we saw tons of wildlife with the exception of the elusive wolf.
