If you just keep driving past Myrtle Beach, you'll happen upon Pawleys. It's known to some as the home of the hammock and if you want an original Pawleys Island hammock, you can buy one at the hammock shops. Like I wrote earlier, I came here with my family during college and thought this place was a big yawn. However, as a grown up, I think it's a great vacation spot and a wonderful place to live.
There's a little something for everyone. If you like ghost tales, ask about the Grey Man, the confederate soldier ghost that comes to warn of inclement weather and hurricanes. If you like to golf or to jet ski or to fish, there are plenty of options for that, too. Brookgreen Garden, a sculpture garden situated on a former rice plantation, will amaze you with its stony-eyed Pegasus, a statue larger than a small house!
Huntington Beach State Park offers hiking and so forth. There are also bike paths in the Litchfield Beach area (just a hair north of Pawleys proper) and in Murrell's Inlet where you can hang out at The Hot Fish Club or the Dead-Eye Saloon for a cold beer.
The best advice I can give to someone who wants to vacation here is to NOT come during bike weeks. No offense to you riders out there, but if it's not your cup of tea, it's just not your cup of tea. It's loud and somewhat intrusive to those who want to relax non-biker style. Hurricane season might be another vacation planning factor. October and November are really great months here. In November, you might be able to get some good rates.
