There are bicycle paths all over Hilton Head Island. This one stretch though you biked by the road until just a few years ago when they added paths through the trees. The only catch is there is a fairly steep hill to get over. I cut over to the roadside and bike around it. DH bikes over that hill every time he can. He really has to get a running start.
The page also captures some photos on the beach and a good one of the two of us together.
