After reading a ton about how this course suffered from the heavy rains/flooding from earlier in the year, my group decided to go back to one of the most unique and enjoyable courses in SoCal. We were not disappointed! Sure, there were some moist spots in the fairways and other areas that were marked "GUR", but as a whole, Summerly is more than playable. The greens were in good shape, the bunkers were near perfect and the fairways were firm-but-playable (like links golf should be). The biggest difference right now is that when you hit it into the low-lying waste areas, chances are you are under water. You will do well by staying away from the burns and waste areas, and you can score very well here.
One more point: The customer service was excellent! From the pro shop to the beverage cart girl and the restaurant bar, everything was great!

Certainly a great course and facility. Great conditions and staff. #6 is still one of the most beautiful holes anywhere.

Everything keeps getting better here. With maturity comes better playing conditions and scoring. A must if you're in Mesquite.

As I stated from last year: Incredible, if not one of the best courses ANYWHERE. Once they get their clubhouse done, this place won't be touched!!!

Fun course that definitely needs to age. Playing way too fast for this kind of set-up. (If it says 220 to the layup spot, play for 180, trust me.) A couple years from now it will be a top course in the area. Big potential, but I disagree with the previous reviewer, -it is not as good as Wolf Creek, but not too far behind and you will score better.
The club house, driving range and staff all both top-notch and the course will certainly get there soon.

The course was in very good shape with the exception of the 428 yard par 4 #5 being washed out and made into a 126 yard par 3. This might have been OK, but there was no prior warning to our group of 20, plus we were forced to hit off of a mat. (I hate hitting off of a mat!) Other than that, everything else was great.

Play here very often. They had a notice on GK that they were aerating 4-4-11, but took it down and didn't aerate. They then aerated 4-11-11 with no notice. Did they need to aerate?, yes. However, the mis-communication is inexcusable.
Other than that, the course is "ok" for now, but they really need to get this place more lush. The rough is almost non-existent and the fairways are way too thin this time of year. The greens will most certainly bounce back to their usual perfection in a couple weeks and the bunkers are much better than they were this time last year. The tee boxes are very good.
One other thing: They are now allowing jeans and a t-shirt as acceptable golf attire. VERY BAD DECISION! With crappy dressing standards comes crappy golfers who don't care about course etiquette and conditions.
Hello?, management?

This place is definitely the jewel of Inland Empire golf. Other than the first two holes being very similar to each other, the rest of the course is one unique hole after another. Hit it in the fairway and your chances of scoring well are very strong. Miss the fairways and troubles/high scores await.
Fairways, rough and tee boxes were all almost perfect. The greens were also in excellent shape, but a little slow. (Which makes scoring much easier, because if these babies were fast we'd all be in trouble.) The bunkers were firm and consistent.
The staff was also very good with Joshua in the pro shop leading the way. Somehow, our tee times got "misplaced", but he came through like a champ and got us off right on time.
All-in-all, a great course well-worth the trip to Beaumont.

Course is OK for now.
Fairways and rough are very spotty at best. Way too many dormant spots with patches of green clumps throughout. Very thin/dead grass off of a downhill lie is just not fun.
The bunkers and tee boxes are pretty good, but don't expect fluffy lies in the bunker and a perfectly level stance on the tee.
The greens are very lush and role at a decent medium speed. However, if your putt loses speed, it will get off course some of the times.
The big plus for this course is the staff and the adjoining restaurant. Top notch all the way! The food is always very good and has very reasonable pricing. Can't go wrong with their superb breakfast sandwich.
Overall, give this course a few weeks to "fill-in", and it will be well-worth the very reasonable prices they charge here.

Incredible facility! From when you arrive in the parking lot to when you leave, everything is well taken care of by the entire staff. The only thing that I can complain about was the white bread instead of sour dough that I asked for in my turkey sandwich at the turn.

The practice area is well-worth an early arrival before your tee time, because of of the beauty, set-up and variety for all parts of one's game. The driving range is gorgeous and even has a gentleman cleaning your clubs after each use! The sand and chipping area is very well kept but not overly large. The putting green is right by the 1st tee and the starter is right there giving you the low-down on the course for first timers.

The course is a thing of beauty with conditions that are top-notch across the board. Greens, sand, fairways, tee boxes and rough were all close to perfect. Expect at least several three-putts on these greens because of the undulations, speed and size, but not due to poor conditions (because there aren't any!). Playing this course is a treat but can be very difficult because of one's lack of knowledge about each hole. My first wish was I would like another shot at it having seen the entire course and its forced carries, blind shots and 'best places to hit it' knowledge.

I was treated to the round which made it even better, but couldn't afford it on a regular or even irregular basis. It was definitely worth every penny, -I just wish it took fewer pennies to play!

Played 2-16-11 when it drizzled occasionally, had 10 mph winds and was a little sunny at times.

Course conditions: Greens, fairways and tee boxes are by far the best in the IE right now. The rough is a little thin now, but that is to be expected being winter time. Bunkers are firm but playable.

Staff: As always, true professionals through and through, and as friendly as it gets.

Layout and location: This course has it all. Long and short par 4s, par 3s that are both fun and difficult at the same time and a couple reachable par 5s that punish you if you miss it in the wrong spot. All of this just off the 15 freeway in Mira Loma in a secluded spot with no homes to be seen!

Overall: Can't miss!

Played 2-9-11.
Staff: Very nice and accommodating.
Carts: New with GPS. Awesome!
Tee boxes: Very uneven and bare. They seriously need to redo them.
Fairways: Way too many bare spots that never seem to get fixed. Other than that they are a little thin due to the winter cold.
Rough: Thin but very playable.
Sand: Inconsistent with small rocks and pebbles throughout. Too bad, because they are very well placed and help set-up a nice layout, with the exception of the right fairway bunker on #5, which needs to go.
Greens: Fast-but-bumpy. Not a good combo! These greens are very well shaped with some fun undulations, but the bumpy inconsistency makes them almost impossible to putt on.
Overall: Well-worth the price for weekdays right now at 29 bucks (with an emailed coupon), but I sure wish they could get the course conditions back up to 'par'.
