The 9-hole "Sherling" course at the The Robert Trent Jones Golf Trail At Cambrian Ridge facility in Greenville, Alabama features 3,681 yards of golf from the longest tees for a par of 36. The course rating is 75.4 and it has a slope rating of 142 on Bermuda grass. Designed by Robert Trent Jones, ASGCA, the Sherling golf course opened in 1993. The Sherling nine may be the best nine on the entire trail. Drama takes center stage at Sherling's ninth hole which marches straight uphill past a deep ravine strewn with ochre boulders to a lolling tongue of a double green shared with the ninth on the Canyon nine. Above this green is a clubhouse set atop the highest point in Butler county, its verandah serving up expansive 30-mile views of Southern forest land.
