We stayed at Huntington Beach State Park in late winter/early spring in 2012. Loved it !!
Much to do there. Atalaya is on the grounds. There is a nature center. There are many kinds of critters to watch the inland waters. Brookgreen Botanical Garden is nearby..........I am not a flower person, but I could have easily spent a day there.
We took our canoe and did a 1/2 day trip around the inlet. We biked to the town and had lunch 1 day.
Did I mention there it is a great beach !!
