This park is not in Glenwood proper, but rather above it: gondolas rise 1,400 feet from the valley floor up the side of Iron Mountain, where visitors can not only tour a cave, but also ride the Cliffhanger, the highest-elevation roller coaster in the U.S., and other amusements. The centerpiece of this park is the historic Fairy Caves, which were first visited by tourists in the late 1890s. The standard cave tours offer handrails and stair cases, but most of the caves have been left in as natural a state as possible for the Wild Tour ($60) which is for individuals who don’t mind crawling through dirty narrow passages wearing knee pads and helmet lights. Allow several hours.
