We recently visited Mt. Trashmore with my little boys. It had been a long time since I had been there. So I was pleasantly surprised to remember that their kids area was so huge and so much safer than many other parks. All of the climbing areas were enclosed so that the children could not jump off, well the littler ones anyway. There were so many mazes and things to do. It is a wooden structure, so not incredibly hot.
There is a restroom and soda machines very close to it also.
Well, if this weren't enough, Mt. Trashmore is also a large hill that the kids can run up, roll down, or climb the stairs. There is also a pond with many waterfowl. There is a jogging or bike path to take. And there is also a skate park that is very nice.
I am sure I am not even telling everything about this park. Please check the website and know that I think it is awesome!
