Holy Terror Mini-Golf in Keystone, South Dakota

You'll be screamin' Mulligans at Keystone's only 18-hole mini-golf.

Come have a rip-roaring mini golf adventure at Holy Terror Mini Golf! This mining-themed 18-hole mini golf course is named after the last functioning gold mine in Keystone and will have you and your family screaming "mulligan" as you make your way up a pine covered mountain, under the mining sluice, and down to the picturesque stream and water wheel. After your golfing adventure, cool off with a beverage from Grapes & Grinds Coffee Shop & Wine Bar or take a stroll through US presidential history at The National Presidential Wax Museum - both of which share a parking lot with Holy Terror Mini Golf. Open seasonally from mid-May through the end of September. 

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.
