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!

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.
