Now as to Wildlife there is no correct answer, the time of year and weather will have a lot to do with that. Scott didn't have much luck in the park, I how ever shot Grizzly, caribou and many Moose with the 18-135. Saw over a hundred Moose, many Grizzly, Dall Sheep. Weather was bad, well into Sept, so the bears were feeding heavy at lower elevations. Moose were rutting and stopped traffic for 30 minutes at one point. In June this will not be happening. I did not see" the mountain" because of weather, 3 days and no Denali showed for me. It was a trade off, bad weather equals lots of Wildlife, good weather = good Landscape and maybe a great shot of the Mt.
We were there in July each time, so your September visit definitely would have been much better for wildlife viewing in the park. As for seeing the mountain, on our first visit it was out for just one hour over the two days we were around the park. However, on our more recent trip, the mountain was visible the entire three days we were in the area. We were extremely lucky in that regard.
