Honduras
Guanaja is the most remote and least developed of the main Bay Islands, valued by divers for its comparatively pristine reefs.
Guanaja lies about 70 km off the Honduran north coast and roughly 12 km from Roatan. Its warm, clear waters support an extensive coral reef forming part of the Mesoamerican Barrier Reef System. The wreck of the Jado Trader, a 260-foot freighter sunk in 1987, is described as the island's signature wreck dive. Low visitor numbers are cited as a factor in the reefs' condition.
