Holy Terror Mini Golf Course

609 Highway 16a
Keystone, SD

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 will add to the realistic experience that only Holy Terror can offer!
