6 Warm-Weather Adventures
Arkansas' Ozarks brim with caves, caverns, sinkholes and underground rivers ripe for exploration. Visitors at Blanchard Springs Caverns in Mountain View tunnel through subterranean tubes into areas rarely seen on the Wild Caves Tour. Those who prefer to remain upright wander 200 feet into the earth to view stalactites, stalagmites and flowstones. Awaken your inner spelunker and come on down! The caves even stay warm (50s-60s) in winter (800/264-0316; ozarkgetaways.com).
