Antigua has some excellent diving, with coral canyons, wall drops and sea caves. Marine life includes turtles, sharks, and barracuda and reef fish. Antigua's sheltered western coast is good for inexperienced windsurfers, while the exposed eastern coast has onshore winds good for slalom and wave-slalom sailing. The other major water sport is game fishing - there are plenty of marlin, tuna and Wahoo.The historical society, which operates the Museum of Antigua & Barbuda, sponsors a monthly cultural or environmental theme hike. Walks average about 90 minutes in duration and typically include visits to old estates or interesting landscapes
