Diamond Bar Golf Course

Course layout is nice. Nice big greens. well maintained landscape.

Always an enjoyable round here- challenging but fair.

The biggest issue is their greens. They are still fairly new- but is they have huge divots in them- that impacts your putts. It almost had to be an auto 2-putt on many of the greens because of all the divots.

They need to find a way to fix this problem.

The fairways had too many hardpan dead spots. The greens had divot marks everywhere. I played here less than a year ago and the course was in much better condition then. I bragged about it to my friends who played with me and we were both disappointed with course conditions. I was a little embarrassed because I had talked it up so much. I doubt my friend will want to come back.

they put 5-8 mimutes per group, super slow play evrytime.

First time since the re design it was very good the greens where a little rough due to irrigation

The course did not notify us before booking the tee time.

Overall the attendant was late so start of play was a bit confusing and we couldn't grab coffee or hit practice balls at the range...

The putting greens were very bad. Several unrepaired divots made it difficult to putt at aver hole. I did not expect this for the recent renovations on the course. I waited long to play this course and was disappointed. I likely wont be coming back.

Started 2:50 on a Friday afternoon no starter no Marshall . A foursome of very young kids ahead of us walking . They actually played quickly , at hole 3 it bottle necked 3 groups ahead of us . The kids waited patiently but then people behind us started cutting us and them killing the pace of play . It took 3 hrs for 9 holes . I thought it was bad last time I was there it got worse. The kids totally respectful with talent in playing and then yahoos that can’t play cutting and looking for there ball for 15 min and driving on the green . No Marshall . Great course if you play early only. No not a one off only day wasted my time money .

Always a challenging layout- but a fun track.

After redoing many of the greens during the remodel- they have been very hard. Those greens are now softening- but the divots are taking their toll. The greens are very pocked and affects the roll of your ball. Not sure how they will address this moving forward !!

Other than that- always a fun round on this course.

The course and pace of play were great today at DB. You get great value for your money here.

If you can avoid (or bypass) a slow group in front of you, then the course plays fast. Did 9 holes in less than 90 minutes.

The first time I played this course, it took us 3 hours to complete the front 9. No marshall in sight, no sense of direction from anyone. I left after 9 holes. On 3/29/26, on a last minute tee time, I decided to give it another try. Let me say this, if you want to put in an 8 hour golf shift, this place is it. Never again. It took 4 and half hours to play 12 holes. Again, no marshall. Nothing. This is insane. Course is next to the 57/60 freeway, keep that in mind.
