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 watertank, thru sluices, over a waterwheel and into a millpond. They even have three kinds of artificial turf that simulate fairways, sand traps and rough.

It was a lot of fun. Lots of sloped holes that were hard to complete. The side of the hill layout was cool, overall fun. It was a hot day and I kept standing under the trees for shade, long course.

Minigolf is one of our favorite vacation activities, but this course is so off balance that it is almost too frustrating and maddening to finish the game. The first few holes are pleasant, but after that, there are hardly any areas that are level enough...More

This is probably the most challenging mini gold course I've attempted. I wouldn't necessarily recommend this for families with young children because it takes some time to get through the entire course and each hole gets gradually harder as you work your way up. Nevertheless,...More

It was a convenient location to our activities for the day (Tramway, Mt. Rushmore and Pizza), but as a mini-golf course was really sub par! We hadn't read the reviews beforehand obviously. Agree that there are no level areas to start your putt and many...More

This is by far the hardest mini golf you will ever play. Some holes are basically impossible. Expect many scores in the teens per hole. Most are straight up hill and if your ball doesn't go in it rolls all the way back to start....More

This was a fun yet challenging golf course that is built into the side of a mountain. Several of the holes are impossible to make. With all that said our family had fun playing a round together.

Hello! Sadly, no. The course has many, many stairs as it makes its way up the mountainside and back down. The coffee shop/wine bar and the National Presidential Wax Museum, which we also own and share the same parking lot... More

Yes actually! The river, sluice and water wheel are up and running. The whole place got a paint job! Carpet has all been replaced and we have spent a ton of time landscaping! Come check it out!
