High atop the mountains lays one of the most adventurous theme parks around. A zipline over the edge of the mountain, roller coasters, and other thrill rides combined with cliffs- could it be more thrilling? The adventure starts at the parking lot which is at the base of the mountain. Attendees take a gondola to the top of the mountain. Glenwood Cavern Adventure Park has a Wild West theme and includes cave tours, 4D movies and other attractions. Also, at the base of the mountain is another popular destination, Glenwood Springs.
