Diamond Bar Golf Course

5 hour and 30 minute round on a Friday...plus the coffee shop and bar closed before 3pm.

Expect a long day and hitting off tee boxes in worst shape than the fairways, basically dirt with patches of grass in between. The course layout is great but overall conditions and pace are very poor.

only 4 minute between groups, can you believe that?

Just make sure sand bottles are filled so golfers can repair divots or course will deteriorate over time

Super slow pace. There was a marshall but they just drove around and didn’t say anything, just waved and kept on going. Haha Just be prepared for 6 hour rounds

This course isn't worth coming to even on a hot deal, let alone to play for free. The course condition is decent and the staffs are great but the SLOW pace of play can't make up for that.

Good muni course. Bunkers are in great shape. Course is in decent shape. Greens are good. Carts are ok. Just short of a 5 star rating. Definitely will be back

It took just under 3 hours to play 9 holes and 5 hrs 45 mins to play 18. What I learned is that the book every 10 mins but once ever hr they book a time at 5 mins also they over book the back 9 start so even if your the first to tee off you will come to a stop at the back 9. I didn’t see the Marshall once, and I wish they took more pride in the pace of play this was terrible.

Tee time was 8:50 and I finished at 2:40

This was my first time playing here. The course was recently renovated and it was in great shape and very scenic. The only con was the play was super slow. You had 3 to 4 groups on a tee box at times. Maybe the tee times could be spaced out a bit more to rectify this issue.

First time I played since the redesign of the course. Nicely redone and great track. Tee times are hard to get but worth it. Going to play here again

This course has never been so bad since the GM left couple of months ago this whole course is ran by kids & even the so called Managers inside then office are kids 😑 I see nothing but kids running this course i can tell the staff years ago was way more experienced i see customers complaining all the time in go in the pro shop trying to pay & play this needs to be addressed real quick by upper management & the county needs to be contacted to remove all these inexperienced staff especially the kid running this circus ,

Just wondering who runs this course very bad managed i paid top dollar to play non ranked bunkers divots on almost all the greens people don't repair it at all to bad since the grand opening was very nice now I see the reviews only @ 3.6 the only positive thing I saw was an older white guy i think he was the marshall repairing the divots and fixing the damaged rope that aligned the greens i saw kids working in the pro shop just sitting around and talking while the old gentleman fixing the divots and repairing other damaged things around the course , to bad the course is spiraling downward the rounds are long also 5.30 hours long & they cram everyone real tight maybe business is bad.

I’ve been playing here the last few weeks and the experience has been pretty disappointing. We usually book tee times around 2:27 and pay for 18 holes, but we can barely finish 9 before it gets dark because the course is way too overcrowded.

I’m not sure why so many groups are sent out at the same time. There are also a lot of walking groups, which slows down the pace even more, and some players take multiple practice swings or even hit multiple balls on the tee box. The worst time, there were four groups backed up on a single hole, all just waiting to hit.

It really feels like the course management needs to improve spacing and scheduling. Otherwise, it’s hard to justify coming back.

I had a hotdog from the restaurant and the bun was dry.

We’ve been coming to Diamond Bar Golf Course for over a year, and it’s disappointing to see how far the experience has declined. The place needs a serious overhaul, not just of the course itself, but of the staff and management as well. If I were managing this course, I would be embarrassed by the poor conditions, the lack of consistency, and the overall attitude of the employees.

Course & Grounds:

The condition of the course is horrific. Several fairways are unplayable; you can hit dead center and still end up in a pool of mud. These issues have persisted for over a year with no sign of improvement. There’s also no enforcement of pace of play, making rounds drag on unnecessarily.

Even worse, we’ve repeatedly had problems with a groundskeeper following our group during play. On multiple occasions, he has moved tee boxes and even changed flag positions on the green while we were still playing the hole. It’s unacceptable and completely ruins the experience. Management failed to address this properly when we brought it up.

Staff & Management:

The morning staff are consistently rude and dismissive. One employee in particular greets guests with sarcasm and a condescending tone. Management’s handling of customer issues is just as poor. When there was a simple check-in mix-up that led to a $30 overcharge, instead of resolving the issue professionally, the manager argued, defended their mistake, and offered no proof of our supposed “error.”

Food & Amenities:

The cart snacks are subpar, and the restaurant food has been even worse. Two members of our party got sick after eating there on separate occasions. For a course in this area, the lack of quality control is shocking.

Overall:

Diamond Bar Golf Course needs new leadership that takes responsibility for both the condition of the course and the customer experience. The problems here are ongoing and widespread, and until management steps up, I cannot recommend this course to anyone.
