The Towne Center at Gulf Place is an easy two-block walk from Full Abalone. The center contains several restaurants, Miss Lucille's coffee shop, a pharmacy, clothing stores and a place to rent bikes, kayaks and beach gear.
The Santa Rosa Beach Club golf course and club is about one block from the house. The club is open to the public and has a dining room that overlooks the beach.
Tops'l State Park, a couple of miles up 30-A, has a great undeveloped beach that you can reach by bike or car.
Terrific sunsets at Santa Rosa Beach. Here's one on Oyster Lake.
And one more on Dune Allen Beach.
