This park is beautiful. I have been going to Clifty for the last 20 years and I've never once had any problems with this park.
It has always been very clean. Some parks I've been to in the past I've wondered if they even have any one there to upkeep the bathroom, or fallen limbs and trees, or even just to make sure that there is no trash thrown on the grounds.
The pool area is super nice, I love taking my kids there. They even saw their momma jump off the diving board for the first time there (Or slide off anyhow)
The falls are so majestic and the trails can get steep but as long as you stick to the path you will be fine. I am even thinking about investing in a walking stick to help out with my hip on the harder trails. This is a definite must see if you love to hike, camp, or swim! A great weekend getaway
