Augusta National Augusta has changed dramatically over the years. In 1999, foreshadowing the monumental course renovation that would come only three years later, Augusta National unveiled what at the time were considered radical alterations -- the first rough, or "first cut" in Masters-speak, and new back tees on the 2nd and 17th holes, among other tweaks.

St. Andrews Old Course No. 4 on Golf Magazine's Top 100 Courses, the Old Course at St. Andrews is set directly in front of the R&A headquarters. Here is No. 18 from the 2010 British Open Championship.

St. Andrews Old Course For the 2010 Open, the 17th, better known as the Road Hole, was extended with a new tee box 35 yards back and to the right of the one pictured, making one of the hardest par-4's in golf even harder.

Pebble Beach In the foreground of this photo is the 6th hole, a 523-yard par-5. The 6th green leads directly to the tee of the par-3 7th, and then on to the toughest stretch on the course — holes 8-10. After the 10th, seen here in the background of the photo along the water, players get a break with holes 11-14 (back left), which are a safe distance from the cliffs.

Pebble Beach The entirety of the world famous par-3 7th hole can be seen in the foreground of this photo. Though the 7th is short, playing only 109 yards for the Open, it is no simple task. The green is well below the tee box, and hitting it long or left guarantees a wet ball.

Pebble Beach This view shows the treacherous stretch of holes 8, 9, and 10. These holes, all par-4s, have come to be known in some circles as the Cliffs of Doom — and for good reason. Many believe it is the hardest (not to mention the most beautiful) stretch of par-4s in the world.

Kiawah Island Ocean Club Hole 9, 494 yards, Par 4 The outward nine ends on a demanding two-shotter surrounded by trouble. "The big deal on this hole is that the green is a little bit offset, so the ball has to be turning right to left on the second shot or they’ll have to carry it to the green," says architect Pete Dye. On a fast, windy day, that might mean a third from the deep pot bunker over the green. (Source: KiawahResort.com)

Kiawah Island Ocean Club Hole 16, 581 yards, Par 5 Downwind, pros can reach this straightaway par-5 in two. Into it, and No. 16 demands three precise shots to navigate the pond, dunes and steep-walled waste bunkers that guard the hole.

Kiawah Island Ocean Club The Ocean Course at Kiawah Island, site of the 2012 PGA Championship, earns its name. Routed through the Atlantic dunes of a barrier island, this Pete Dye layout features unpredictable seaside winds and classic bits of Dye treachery. No wonder Johnny Miller calls it "the hardest course in the country."

Kiawah Island Ocean Club Hole 17, 223 yards, Par 3 The tee shot at this par-3 is one of the scariest on the course. Players must carry a pond to get to this diagonal green. Those who play it safe must hope to avoid the pair of deep pot bunkers that guard the green's left side.
