Wooded islands and clean water inside the Ouachita National Forest.
Lake Ouachita is Arkansas's largest lake and consistently ranks among the cleanest reservoirs in the country. Managed by the U.S. Army Corps of Engineers, its shoreline is protected inside the surrounding Ouachita National Forest — as a result, private development is almost entirely absent, and the lake is dotted with hundreds of undeveloped wooded islands ideal for anchoring, hiking, and swimming. Resorts along the shoreline rent houseboats ranging from mid-size boats to larger group vessels. The lake sits a short drive west of Hot Springs National Park, which pairs naturally with a lake trip as a pre- or post-vacation day.
