Holy Terror Mini-Golf in Keystone, South Dakota
You'll be screamin' Mulligans at Keystone's only 18-hole mini-golf.
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.
A mini golf experience the whole family will never forget!
Challenging, yet fun! The 18-holes meander more than 50 feet up a steep hillside, and then down again, unified by a gold mining motif and rushing water that flows from a water tank, through sluices, over a waterwheel and into a millpond. They even have three kinds of artificial turf that simulate fairways, sand traps and rough.
