If one wants absolute seclusion, North Beach, Barbuda is the place.
After a delightful boat ride from Codington (the only way to get there,) the cottages (there are only 2) are steps away from the beach front.
But there is plenty to do: fishing, sail boating, snorkeling, swimming, shell collecting, floating on a raft or any other water activity all safely done inside the reef plus a visit to the Frigate Bird Santuary is fascinating, or walking the literally miles of serine beaches or just reading a book on the beach (personal experience, a book every 2 1/2 days.)
All the gear required is provided and all-inclusive! No extra fees for anything......
In addition, the accommodations are safe, nicely decorated, clean with maid service daily and the food is quite good especially the fish caught the same day (talking-fresh) and the chef's chocolate cake.
As the lady guest screamed as the couple were on the boat back to Codington after a 5 day stay at North Beach, "I DON'T WANT TO LEAVE!" and my experience concurs.
Next year, 12 days instead of 11.
