Brown County State Park is Indiana's biggest and, in my opinion, most beautiful park. There are lots of amenities that can suit any age of visitor. There are several vistas that overlook the rolling hills of southern Indiana that would rival any even the great Smoky Mountains. However, camping at Brown County has its challenges. Most sites are located along the main thoroughfare of the campground and offer little privacy. Traffic can be a distraction if you are looking for a peaceful night around the campfire.
Nonetheless, Brown County's large trail system, both hiking and mountain biking, can take adventurers over ridgelines, through ravines, and can connect all of the vistas overlooks. Overall, this Indiana gem was one of my most memorable experiences today, and 30 years ago when my wife and I were just dating.
