In pictures: 20-hole Haig Point Signature Course on unique Daufuskie Island, South Carolina

DAUFUSKIE ISLAND, S.C. -- On one of the most unique locations in the world is home to one of the most uncommon golf courses: the Rees Jones Signature Course at Haig Point Club, located just across the Calibogue Sound from Hilton Head Island and Harbour Town Golf Links. It isn't easy to get to — there are no bridges leading to the island, only ferries. And in the community of Haig Point, you can't drive a conventional car. It's golf cars, bikes and walking all the way. You can't even have a gas golf cart. It must be electric.

The Signature Course at Haig Point is actually 20 holes. And it's two courses in one at this private community that actually has 29 holes, including the nine-hole Osprey Course, also designed by Jones. And here's how it works:

The Signature Course has two versions of the eighth and 17th holes. The "Calibogue" eighth and 17th are closer to the water and more vulnerable to tropical storms. They are also more difficult than the "Haig" versions of those holes, all of which are par 3s. There are also Haig and Calibogue tees through much of the course, with the Haigs being the more forgiving of the two. If you play the Haig tees and the two Haig holes, you've played the Haig Course, which is a par 72 that tips out at 6,735 yards. The Calibogue Course, with its more difficult tees and eighth and 17th holes, can be stretched to 7,380 yards.

One of the best aspects of having the Calibogue tees at eight and 17 is that if they were lost due to a storm, the course would still have 18 holes, even if those holes couldn't be rebuilt. Fortunately, over the last couple of decades they have survived all storms, including Hurricane Matthew in 2016.
