St. George's packs a surprising amount into a small space. The best approach is to walk — the town is compact, and the hills mean you get different views depending on which lane you take up or down. Fort George, the Carenage, and the Market Square form the core of any visit; add the museum and botanical gardens and you have a full day. The underwater wreck of the MV Bianca C. is one of the finest dives in the Caribbean and worth planning a day around if you have the gear.
