Holy Terror Mini Golf Course

The Holy Terror Mini Golf course is nestled on the side of a pine-covered slope in Keystone. Named after the last active gold mine in Keystone. The course will have you “screamin’ mulligans” as you putt around gold-flecked boulders, up steep hills, down thru the mine slew, and around the water wheel and bubbling stream. Challenging, yet fun! The 18-hole mini golf course rises up a 50 foot steep hillside, and then descends back down the slope. The first and eighteenth holes are unified by a gold mining display and rushing water that flows from a water tank, thru sluices, over a waterwheel and into a millpond. Three types of artificial turf simulate fairways, sand traps and rough which will add to the realistic experience that only Holy Terror can offer! Located next to the National Presidential Wax Museum & Grapes and Grinds. On the road to Mt. Rushmore.
