Aspenglen is located just inside the Fall River Entrance Station.  Once you have entered the park it is the first left that takes you down to the Aspenglen campground.  There are a few more trees in this area, so you are more likely to find shade.  There are some sites that are specifically for tents and others that accommodate small to medium RV's.  There are no hookups for electricity or water and cellphone service is mostly non-existent.  The sites are spaced more widely apart than at Glacier Basin.  There are bear boxes to store your food, fire rings, and tables.  Three loops, and some walk-in sites compose the layout.  There was a host at the campground.  They did sell firewood near the check-in post.
