Wooden Staircase in the trees

I was in the Lake of the Ozarks area in Missouri and came upon Ha Ha Tonka state park.
There was a bay where people were enjoying the cool water on a very hot day.
There was also a trail leading to a spring fed river and trails to walk leading higher into the forest.
Older folks were happy to use this staircase that ascended to the top of the ridge where they could get a better view of the bay.
