Can play like a desert golf course. Some lost balls out there if you are crooked off the tee. I don't think they let you walk, which means I don't go very often. I'm told they finally made the switch and the first hole is now the old 17th.

Very over priced in my opinion. Greens were alright, but fairways were balding in a lot of areas, tee boxes were beat up, lots of holes were similar. Nice range, and good views, but better value courses are in the area.

How we rank
This ranking uses published scorecard data from each course’s longest men’s tees, the same tee set for every course. Only 18-hole courses with a yardage for every hole, a total that matches the hole-by-hole sum, and a par between 54 and 80 are included, and the tees must carry a single slope rating (55–155) and course rating. Courses whose scorecard duplicates another course’s are left out until the data is fixed. Courses are ordered by slope rating, then course rating, then Course Vaults score. Only open courses with a published Course Vaults score (at least 5 explicit ratings) are eligible, and a page is published only when at least 5 courses qualify. City pages include courses within about 25 miles of Riverside, so nearby suburbs can appear. Rankings refresh about hourly.
