The hardest course I have played, based on rating and slope, is Ko'olau on Oahu. It has been called that hardest course in the US and maybe the world. SSome of the holes are unplayable for most golfers. Many forced carries and dramatic elevation changes. I'd love to play it again.
Golf is so hard anyway, I can't identify an "easy" course. Based on score posted I guess my home course, Boca Royale, would qualify but except for being short (6200 yds) it is tight with los of bunkers and water.
Same here as far as course rating/slope: Ko'olau, it wasn't that bad though, except for the 18th hole. The 18th hole is the hardest hole I've ever seen. The only trouble I found with the course was lack of knowledge of when fairways ended. It was easy to hit it too far and be lost in the jungle. You need to lay up to the right places for the forced carries.
Easiest...nothing comes to mind.
