Disneyland - The Matterhorn!

The Matterhorn Bobsleds or the Matterhorn is an attraction composed of two intertwining steel roller coasters, which opened in 1959 at Disneyland in Anaheim, California. It is modeled after the Matterhorn, a mountain in the Swiss Alps. It is the first tubular steel continuous track roller coaster ever constructed and thus an ACE (American Coaster Enthusiasts) Coaster Landmark.
