Big South Fork National Park. This park, which straddles the border of Kentucky and Tennessee, is beautiful but not highly visited. It is honeycombed with trails and is a great place to get away from the crowds you can find at some national parks. Our hike started with the Twin Arches and took us southwest to the Middle Creek trailhead. There are a lot of impressive sandstone formations. Sadly, there is also a lot of pine beetle damage.
