Dune Boardwalk

The Dune Boardwalk at Sea Rim State Park is a small, elevated boardwalk that takes you from the dunes out to the gulf shore.  It's not much of a hike, but the view is nice and the sound of the waves is very relaxing.  Once you're out on the beach, you can walk for miles up and down the shore if you want, collecting seashells or just enjoying the locale.
