This trip to Cedar Hill State Park was for a homeschooling adventure, so we did not get a chance to do any camping. We took our co-op class here so we could show the kids some old houses and farming equipment they have at the park.
We went in December of 2019 so there were no leaves on the trees which made the park look kind of empty of nature. They had also recently done a controlled burn which also caused the park to look blackened and crispy. From this particular visit, I can't say that this park is somewhere I would recommend for trees or the view. It's possible that spring is a better time to visit this park, but I don't know personally.
Also, it is very close to the city so it isn't the quietest of parks either and light pollution probably doesn't allow for very dark nights or star viewing.
Overall I think the park is great for day trips with homeschools, but I probably wouldn't plan a trip to camp overnight.
