If you really want to hit a good mountain type course not too far from Denver, you have to check out the 20 hole course in Conifer. Just a little west of Denver. Digit covered some good courses around Denver. I would say mainly Badlands is the must play (18 main holes and 9 back in the woods). Johny Roberts is good but gets very crowded with people enjoying the park. So be very careful of where you throw because it doesn't take much to hit somebody. Main reason I don't play the course anymore besides tourney time or bad weather when people stay in. I think if you play early in the morning it's not as crowded either. Expo is a putter/mid-range course unless you can find the long tees and then you get to use your driver a bit more. Bird's Nest is fun and don't let the wind scare you. It's not really that bad on most days. Westy is decent, haven't been out there in a while. Widefield in CO Springs is a must. Kind of a tight course and can get some big crowds out there but you play along water and in trees the entire course. Also, if you feel like making a little more of drive south from there, you should hit the Pueblo course. Played it again this year and forgot how much fun it was. Very challenging course. It also gets a bit crowded and is in a city park with walkers/picnicers. If you want to drive up to Fort Collins, they have a very good course in town. Then a little further northwest of that is the two private courses (mountain type play but not way up in elevation) that are beautiful.

If Aspen has the course open at that time, it is well worth the $$ for the ride up the mountain on the ski lift to play at like 11,000 feet. Some absolutey beautiful views and some great holes to play. Bring the oxygen mask. I had to stop and catch my breath a few times on that one and that was just walking to one of the holes. If you go really west, you should stop in and play on Fritz's home ground in Palisade. Never played that course until States this year and would love to go back and play it again. Terrific course they have out there on the western slope. Those are the main ones I have played the last couple of years. There are a few more mountain courses like Montrose, Snowmass, Steamboat and Winter Park that I hear very good things about but haven't made it to those for first hand experience. Oh yeah, if you are driving to Denver, you should make it a point to go through Fort Morgan and play the course there. I think it is 22 holes. If you are here during High Plains Challenge (A-tier) tourney, they set up another temp course that will challenge the best of them. So something to think about. Anyway, hope this helps you out.
