Arkansas Ozark Mountain Caves
North Arkansas is part of a geologic area known as the Ozark Plateau and contains over 4,500 known caves. While most of these are undeveloped, seven of them are open for tours. In these "show caves", you experience adventure, see beautiful calcite formations, learn of historical uses of the caves, and view fossil remains of creatures from the past. If you think our mountains are beautiful on the surface, you will be awed by the beauty below!
Show Caves 
Of the seven show caves open in North Arkansas, two are within a 30 minute drive from Harrison. Crystal Dome, and Mystic Caverns are located seven miles south of the Harrison city limits on Arkansas Scenic 7 Byway with entrances about 400 feet apart. Less than a one hour drive from Harrison, Cosmic Cavern is located near Berryville, Arkansas, and Onyx Cave is located in Eureka Springs, Arkansas.
A little more than a one hour drive from Harrison, to the east is Bull Shoals Cavern, or to the west is War Eagle Cavern. And, about two hours drive from Harrison to the southeast is Blanchard Springs Cavern (the only cave in the U.S. operated by the U.S. Forest Service).

Cosmic Cavern is one of Arkansas' hidden treasures. You will see 2 bottomless cave lakes during your 1hr and 15 minute tour with one having cave trout in the clear, dark waters. The first lake, South Lake, has had trout in it for nearly 50 years. Some trout have gone blind and most have lost their color. The bottom or end of these lakes have yet to be found. Cosmic Cavern has been named as one of the top 10 show caves in the United States, so don't forget your camera as there are several photo opportunities throughout the cave.
During the cave tour, you can see the newly discovered area "Silent Splendor". Silent Splendor has been hailed as a must see in Arkansas. Silent Splendor houses one of the longest soda straw formations in the Ozarks measuring over an incredible 9 feet! As you journey along the inspected and safe walkways, you will see many unique and beautiful formations. You will witness stalactites, stalagmites, flowstones, sodastraws, helictites, cave bacon, draperies, and many other speleothems along the cave routes. Also, among the awesome cave formations, you will also get a chance to see a rare and threatened salamander, the Ozark Blind Cave Salamander.
