Highland Rim is a short nine mile drive outside Nashville along I-24 to mile 31. I checked out this hidden gem for the first time last weekend. I was skeptical of all the wonderful reviews I read given such a reasonable price, but there was no need. The course is beautiful, and the GPS equipped carts are fantastic. They will show you a fly over of the whole (well-needed given the bluffs the course plays through and blind fairways), plus give you approach distances to front/middle/back of each green and how many yards to clear bunker and water hazards.
The tee boxes are flat, the fairways tight, and bunkers well maintained. I love that the tees are not colored in the traditional sense but randomly colored and have an associated distance -- this is something "While We're Young" is pushing for to speed up the pace of play and I think it's wonderful and is great to see implemented. Something I found odd however was the distances from these tees on individual holes. We played the second to last tees, which had great par 5 distances of about 500 yards and longer par 3s at just under 200 yards, but many par 4s were just over 300 yards which is just too short for a par 4. The other downside is the greens. They have recently replaced their greens with Bermuda Grass and it's still growing in (i.e., very uneven green surfaces). Give it some time, and this will be one of the nicest courses for the price in the Nashville area.
The service is great, and the gentleman working when we played gave us a special discount because of the green condition. Could not ask for more. I will certainly be back and would recommend this course to anyone.
