If you like hiking, Arkansas is paradise. One of my favorite trails goes deep into a canyon at Petit Jean State Park and ends at Cedar Falls. When it rains in the spring, the falls change from a trickle to a cascade.
Petit Jean State Park is one of the best parks in Arkansas. Aside from a restored lodge atop the mountain, there are miles of excellent trails, waterfalls, trail riding, a petting zoo, caves, camping, rock formations, and a tragic love story. At the visitor center, get hands on with some Arkansas wildlife—posthumously.
