4. 6th at Royal Melbourne West -- Par 4, 428 yards -- Victoria, Australia
This sharp dogleg right features several signature Alister Mackenzie stylings, including a constellation of furry-browed bunkers, set 220 to 240 yards from the tee. Carry them, and the approach gets easier. But bail even slightly left, and you’ve got a hanging lie to a green that spills precipitously from front to back.
