At 5,550 acres (2,200 hectares), Arkansas’ Hot Springs National Park is the second-smallest national park in the country. If you’re looking to do some real wandering, try the nearby 1.2-million-acre (500,000-hectare) Ozark-St. Francis National Forest instead. There you’ll find waterfalls, high bluffs, gentle mountains, spring-filled caverns, dense hardwood forests, and swirling lakes and rivers.
Popular activities include hiking Pam’s Grotto, climbing Sam’s Throne, or kayaking the Buffalo National River, one of the longest undammed rivers in the Lower 48. It offers both gentle floats and rapids, and when night falls, it doubles as a designated International Dark Sky Park.
