Barbados is the easternmost island in the Caribbean. It is completely surrounded by the Atlantic Ocean and not touched by the Caribbean Sea. Barbados is a mostly a flat coral island with excellent beaches, but there are rolling hills and many deep ridges and gullies, with an interesting distribution of flora and fauna. Within the Barbados coral core there is a vast array of caves and underground lakes, which provide an excellent supply of drinking water that is amongst the purest in the world. Geologically Barbados is unique, being actually two landmasses that merged together over the years. This and other anomalies make this Caribbean Island quite phenomenal, and there are geological structures that you will find only in Barbados.
