We saw at least one of nearly every “mega-fauna”: grizzly bear, moose, caribou, fox, dall sheep, sea otter, duck, sandhill crane, bald eagle and golden eagle - but not wolf. But overall, we did not see a lot of wildlife. The bus driver at Denali pointed out that in mid-July, the mammals are mostly in the higher country. Very early and late summer are apparently better times to see wildlife.
Although we considered “treating” ourselves to a motel room or cabin now and then, we ended up camping every night, many of them in the rain. The campgrounds always had plenty of empty spots and many had showers. The long days are well suited to camping. Although we never actually saw it happen because of the clouds, sunset was around 11:30 pm and sunrise about 4:30 am. We could spend a long day sightseeing or hiking, and then roll into the campground at 8 or 9 pm and still have plenty of time to set up camp and make a late dinner. Sometimes we hiked after dinner until 10 or 11 pm. I took an extra dark brown tarp to put over our tent to make it darker - that helped us sleep well. I generally woke up at least once each night because it was so light, only to look at my watch and see that it was only 1:30 or 3 am.
