Explore the haunting beauty of three natural limestone caverns connected by man-made tunnels.  This National Monument is located on the Alpine Scenic Loop in American Fork Canyon. The cave system is well known for its colorful formations, unique helictites, fault-controlled passages, alpine surroundings, and rich history.
The 1-1/2 mile-long paved trail (1,160 feet elevation gain) to the cave is also a popular attraction. The trail provides spectacular views of the geology and beautiful scenery of the American Fork Canyon. 
 
The man-made Timpanogos Cave system joins three natural caves that contain at least 42 types of cave formations-an unusually large variety. The uniquely colored cave features include unusual combinations of delicate helictites and anthodites in quantities not found in other caves worldwide.  
 
The cave is open from mid-May to mid-October (Tours will be available only on the weekends of Oct. 3-4, 10-11 and 17-18, then the Cave will closed for the 2009 season), weather permitting.  A fee to American Fork Canyon is required for use of Forest Service facilities.
