8) Big Bend National Park
Big Bend National Park borders Mexico, with the Rio Grande as one of the boundaries. It’s quite remote and, therefore, one of the least visited parks in the United States. This makes it perfect for those looking for solitude and to get away from it all. It has more than 150 miles of hiking trails through desert, along the river and in the mountains. Bicyclists have access to 100 miles of paved roads and 160 miles of dirt roads. Other activities include boating on the river, bird watching, fishing, and some of the best stargazing in the country. The park has traditional camping, as well as RV hookups. Chisos Mountain Lodge is inside the park offering rooms and cottages. Some of the small surrounding towns offer additional lodging and meal options outside the park if you are willing to stay a few miles away.
