Beware... we brought bikes with us and were really disappointed with what the island touts as "more than a hundred miles of bike trails". The ones we were on were nothing more than sidewalks right beside the road... where bikes *don't* actually have the right of way.
We headed south on the road from Disney. There are stop-signs for the bike paths at every business' driveway. Apparently this is due to the number of bike/car accidents that occur on the island. There were some places where you could bike for a fairly long way between driveways, but many times, there were driveways every couple hundred feet or so. Talk about frustrating. And you have to look hard over your left shoulder to see if any cars are coming (who don't have a stop sign and therefore have the right of way). Most of the drivers were very nice and stopped to waive us on, but you couldn't count on that... plenty didn't.
It's made worse by the island ordinance that limits signage in front of all businesses to a uniform, tiny, green-on-tan sign that is so small, you can't see it 'til you're right on top of it. I found myself several times quickly taking a sharp right into the parking lot of the business I was looking for as I couldn't see it when approaching (due to that ordinance) until I was right there. That sharp, immediate right with no time for directionals included crossing the bike paths on the right side of the road. No wonder there are so many car/bike accidents on Hilton Head.
