Colossal Cave
Just a few steps in and you know… you’re definitely not in Kansas anymore. Sunlight disappears quickly. The air is a cool 70°. And in between gasps of wonder you’d swear you can hear your own heartbeat. Miles of narrow passageways and large halls are adorned with otherworldly stalactites, stalagmites and other bizarre forms. Get ready. For the next hour or two you’ll be immersed in a faraway world you won’t soon forget.
