Elbow Cay  
Elbow Cay has two settlements

Hopetown:
Home to the candy-stripped lighthouse built by the British Imperial Lighthouse Service in 1863.  You can climb the lighthouse steps and enjoy a picturesque view of Hope Town Harbour and surrounding cays.  There are quaint, pastel colored Loyalist style homes.  Several good restaurants, and old wooden school house, Wyannie Malone Museum and a Dolphin Whale exhibition near the Post Office.  There is no driving in the Hope Town settlement, so just pull you boat up to the restaurant's dock or take the ferry.  There are also several gift shops in Hope Town.

White Sound:
You'll find the Abaco Inn here.  They serve excellent lunches and dinners.  It's a charming and quaint resort.  The view, of the Atlantic, from their inside/outside dinning area is breathtaking.  You can even watch the surfers, or take a dip in their oceanside pool.  Just pull up to their dock in your boat or take a ferry.  This is definitely 'a must see' place.  There is also Sea Spray Marina and Resort, a fifteen minute walk or a five minute boat ride from the Abaco Inn.  Sea Spray also offers a gas dock.

Another must see is Tahiti Beach.  It is located at the southern tip of Elbow Cay.  You can arrive in your boat and stay for hours!
