Nice thing with Vegas is its pretty easy for a direct flight and the cost isn't terrible for how far it is/compared to places like LA, Phoenix etc.. Some of the courses can be pretty expensive but also depends on the season (if you go in summer you can play for little $ but it could be 110 degrees). I found some courses jacked up rates March 1st so late Feb might be the time to do it. I got pretty lucky weather wise as it was between 16 and 22 degrees and pretty sunny. The wind can be an issue depending on the course though and when I drove back from St George to Vegas there were like 45-70 MPH wind gusts across the desert making it a little scary at times lol.
As for the courses I played I'd rank as follows:
Shadow Creek- Hands down the best golf experience I've had in my life, literally felt like I was playing Augusta. Was literally just me and the caddie on the course so felt like I had the entire course to myself. Conditions were so good it was like the course never had been played. Also was expensive so likely the only time I'll play it but I had a comp offer at the Aria for 4 nights so made it a bit easier lol.
Sand Hollow- Holes 11-16 were some of the best I ever played, just spectacular views and really fun golf holes as well. Front 9 was still decent but not quite as great as the collection on back 9. Service/driving range/restaurant were really good as well.
Black Desert- Its a brand new course so there is construction all over in terms of a housing community as well as the clubhouse. Pro shop was out of a trailer pretty much. Conditions were some of the best I've played on with a fantastic practice facility. I wouldn't say this is a course for a high handicap though as I play off a 10 and the front 9 was a challenge. You'd have some shots where you though you made an amazing shot only for the ball to roll down a slope and be 12 feet from the pin. Much preferred the back 9 as it was more open/not as many blind shots. The scenery was spectacular, even better than Sand Hollow I'd say. I played for $250 which included food/snacks/non alcoholic drinks and that was great value for the experience. I could see them raising the rates once everything fully opens though.
Paiute Wolf and Snow Mountain- There are 3 Pete Dye courses out in the middle of an indian reserve north west of vegas. Great courses, conditions, staff, amenties. Only thing with these courses is it can be super windy. When I played Snow Mountain it was like 20MPH with gusts of 30 which made even putting extremely difficult. value wise these were the best courses as I played for $120 and $100 since it was Feb.
Coyote Springs- About an hour drive north of Vegas (on way to St George) This was the toughest course I played and it kicked my ass. The greens were crazy so if you ended up on the wrong side of the hole a bogey would be a victory. If you're a good player I think you would really enjoy the challenge
Sienna and Highland Falls- Both were pretty good courses but certainly a tier below the others I would say. Highland Falls had some really nice views on the back 9 looking down into the Valley of Vegas. I played for around $75-95$ on golf now which was pretty good value for the courses but I wouldn't pay the rack rate of $165 which I think it was.
All in all there was some great courses. I would put all these courses except Sienna and Highland Falls above any Toronto area public courses and even Clublink Courses. TPC Toronto would probably be better than Coyote Springs IMO but thats about it. St George had a bunch of other golf courses as well but I was only there 3 days one of which rained so I didn't get to play others. They also tend to be a lot cheaper than the Vegas ones although nightlife quite isn't the same there lol.
All in all I would rank the area as one of the better golf destinations given the quantity and quality of the courses combined with the weather, nightlife and direct access. Other places we've gone are:
Palm Springs- Fantastic golf but not a whole lot otherwise to do.
San Diego- Amazing City, weather and a collection of great courses that surprisingly weren't too expensive (Coronado might be the best deal in the world)
Tampa/Sarasota- Love the cities but I find Florida golf in general to be a lot of houses, water etc.. and I find bermuda can be a tough adjustment
Miami/Fort Lauderdale- Didn't play the best courses here but found the golf to just be more above average than great.
