If you are looking for an adventure in southern Arizona, you should visit **Coronado Cave**! This amazing cave is part of the Coronado National Memorial and is one of the few open, undeveloped caves in the region. You can explore the cave on your own, without a permit, and discover its wonders. The cave is a large cavern 600 feet long and 70 feet wide, with stalactites, stalagmites, flowstones and other formations. The cave may have been used by ancient people, Apache warriors, miners and settlers as a shelter and hideout. To get to the cave, you need to hike half a mile on a moderate to strenuous trail that climbs 500 feet in elevation. You also need to bring at least two sources of light, gloves, water, snacks and other essentials. The cave is dark, cool and slippery, so be careful and respectful of the cave environment. You will have a blast exploring Coronado Cave and learning about its history and geology!
