The AbacosFrom north to south, the Abacos stretch more than 120 miles, from Walker's Cay to Hole in the Wall. Sheltered harbors make this region popular for yachtsmen, and many North Americans have discovered this is a great place to have a holiday home. Still, the pace is laid-back and the scenery quaint. Don't expect high-rises or shopping malls — the Abacos feature a more leisurely way of life. There are several islands where dive adventures are easily arranged, including Marsh Harbour, Great Abaco and Green Turtle Cay. The wreck of the San Jacinto is a great dive off Green Turtle Cay, and a site called the Catacomb off Marsh Harbour is an intricate cavern system where shimmering shafts of light percolate through the ceiling of the caves.
