    Just such a difficult walk. Caddies are exceptional. Played in 4:40 and it was the caddies fastest loop of the season. (Slowed down for Maintenance). Soft conditions but if it was firm and fast it would be incredibly difficult. Layout is eh. Some really nice holes but lot of blind shots

    Arnold Palmer course that is starting to show wear around the edges. Good layout but gets a lot of event play. Grass range is only for the members of the public course. Some quirky holes but a nice daily fee course

    The course conditions are always great. The course layout to me is very old school and right in front of you. However not that memorable. The holes on the river are very scenic and hole 9 back up to the club house is fun.

    Tree lined course that is always in good condition. Too narrow for my taste and very similar holes. Tough greens sloped mostly back to front. Old school layout that has improved after becoming part of the Legends group.

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 Erin, so nearby suburbs can appear. Rankings refresh about hourly.
