Jack Nicklaus once said of Merion, “Acre for acre, it might be best test of golf in the world.” At less than 7,000 yards from the tips, what makes Merion so distinctive — and testing — is its remarkable variety. Some par-4s are short, others are monsters. One par-3 is tiny, at 115 yards. The other par-3s measure 236, 246 and 256 yards. Holes play uphill, downhill and along the sides of small ridges. The famous par-4 11th, where Bobby Jones clinched the 1930 Grand Slam, is slashed by a creek, while the par-4 16th demands a shot over an abandoned stone quarry that is filled with wild growth of trees and shrubs. In short, Merion has everything.
