I live nearby so I'm a bit biased towards the park. Definitely one of my favorite places to day hike. The trails are well maintained, and the scenery changes every few steps. Lush hardwood forest; plenty of shade for summer hikes. Not crowded at all in the off-season.

We stayed in the Indian Cabin #I11.  There are 4 twin sized bunk beds but be forewarned, the springs and mattresses were ancient during our stay.  There is a small table, a refrigerator, electric stove and oven, and there is heat.  The windows do not open very much so bring a fan if you're camping in warm weather.   The bathhouse is clean and the showers are hot. 

The cabins can be difficult to find in the dark, but they are located just behind the campground offices.  If you pull around to the rear of the building and look across the creek that is there, you cannot miss them.
