How we ranked them

Slope rating measures how much harder a course plays for a bogey golfer than for a scratch golfer; 113 is average and 155 is the maximum. Each course is ranked by the highest men's slope on its own scorecard, from whichever tees carry it. Ties go to the higher course rating.

The list covers courses with a free maps.golf guide whose scorecard we’ve published, and it updates on its own as new guides go live. Numbers are as printed on each course’s card; courses re-rate and re-tee, so check the course’s own scorecard before you play. Running one of these courses and see a wrong number? Tell us.
