I'm from CA originally and can honestly say there is nothing like HH anywhere else. Start with thinking of Laguna Beach in the 70's, when it was still smaller, a laid back beach community, then sprinkle in some southern Civil-war era history, add a lot of summer heat and humidity, a dash of spanish moss, the colors blue and green as you look over the marsh, and there you are.
It's the only place I've ever been where you will see teenagers and their grandparents hanging out on the beach together; very family friendly, no thongs or loud radios, on top of that the ocean is 85 degrees in the summer!
Tons to do---bike/walking paths everywhere (and most are set apart of the main street traffic), kayaking, crabbing, dolphins, golf, trail rides, lots of restaurants, outlet shopping, nature tours, loggerhead sea turtle nesting, para-sailing, tennis. We come here every summer and still find new things to try.
Plus, something about the natural beauty of this place---you find all your cares just drifting away as total relaxation sets in. It's a great place to unwind.
You'll love it....
