Patapsco Valley offers 6 different entrances. Each one provides a several different trail heads and experiences. For camping or just spending a day out on the trail with the kids we prefer the Hilton entrance. There are two huge playgrounds and a youth campground as well as a family campground. The trails we have been on are all pretty moderate to hard but offer beautiful waterfalls and river views. This definitely is a park that takes a while to explore all of it. It cannot be done in a day. Which is nice. It's close enough to home that we can visit often and not get bored.
