In an effort to attract a bit more visitation, many commercial caves are adding new "thrill" attractions such as extreme wild caving tours, dinner theatres, sluicing for gems, rappelling, climbing walls, etc... Taking advantage of their cliff-side perch, Colorado's Cave of the Winds has added their Wind Walker Challenge Course, where a visitor can navigate a series of ropes and cables suspended over a cliff edge to test their balancing skills while fighting vertigo. Price: $15. _http://ww1.prweb.com/prfiles/2011/04/20/8330512/windwalker1.jpg_ (http://ww1.prweb.com/prfiles/2011/04/20/8330512/windwalker1.jpg) _http://caveofthewinds.com/what-to-expect/wind-walker-challenge-course_ (http://caveofthewinds.com/what-to-expect/wind-walker-challenge-course)
