PGA National is a massive golf resort complex with 5 championship golf courses, and was the original home of the PGA back in the 1960's. The courses are only accessible to guests of the resort and members, and are pricey by Florida standards. Four of the five courses are on site, the fifth, the Estate is a few miles away.
The Palmer, used to be known as the General was designed by Arnold Palmer, and is flat and open, a links-style course with grass bunkering and mounding, and water hazards on 16 holes. It plays to 6,700 yards, 134 slope from the championship tees, but there are 4 other sets available. Interesting layout, forgiving, where you can keep the driver out on most holes.
The Fazio course, formerly the Haig, was designed by Tom Fazio, and can play to 6,800 yards with a 135 slope from the back tees. There's water on 16 holes, and 50+ traps, a difficult and challenging course, not for the high handicapper.
The Squire, also designed by Fazio, is 6,400+ yards, and a tough 139 slope from the tips, a links, open type of layout and the shortest of the courses here, with a great collection of par threes.
The Estate course, a short drive from the resort, was designed by Karl Litten, and can play to 6,700 yards with a 138 slope, water on every hole, and well bunkered.
The Champion, was originally a George and Tom Fazio design, but was redesigned in 1990 by Jack Nicklaus. It was the site of the Ryder Cup in 1983 and the P.G.A. Championship in 1987, PGA Seniors' Championship from 1982 through 2000, and has been the home of the Honda Classic. The course is 7,100 yards, 147 slope from the tournament tees. and is definitely the toughest track here. Unlike the other courses, the greens on the Champ are large with a good amount of undulation, and relatively fast, with a lot of bunkering, and water hazards on 17 holes. The 15th, 16th and 17th holes are called the Bear Trap, where Nicklaus thought your round really needed to be tested. Overall the best layout here, and it's always fun to play a PGA Tour course.
