I love this little par 3 course because it's so close to Denver International Airport. I travel to and from Denver several times a year, and I like to schedule my flights late so I can stop here and work on my game.
It's a small, 9-hole course that you can play in under an hour, but for ten bucks you can play as many times as you want. I like to play two balls and play a lot of different shots. This is an excellent way to improve your short game.
Another note: this course directly supports the First Tee Program and is an excellent course to bring your kids along.
In addition, there is a driving range that, for fifteen bucks, you get unlimited range balls. And for you who are really committed to improving your game, there is a McGetrick Golf Academy at the course.
If you are interested in playing an 18-hole regulation golf course, Green Valley Ranch Golf Course is a beautiful golf course that they keep in spectacular shape. However, for you lower handicaps looking for a challenge, I would recommend Buffalo Run Golf Course. This is a tough, links-style course located just down the street.
