Copán's value is carving rather than scale. The site holds the densest concentration of Maya hieroglyphic text anywhere, and the Hieroglyphic Stairway alone carries around 2,200 glyphs recording the dynasty. Rosalila, an earlier temple buried intact inside Structure 16, was excavated by tunnel and is one of the best-preserved Maya buildings in existence. The scarlet macaws over the plazas are there because of a reintroduction programme — worth knowing rather than assuming.
Offshore, Roatán sits on the Mesoamerican reef with the drop-off unusually close to shore, which is why shore diving there is genuinely good rather than a consolation. And in the east, La Mosquitia holds the Río Plátano Biosphere Reserve, a UNESCO World Heritage site on the In Danger list. It is also in a department that has carried a Do Not Travel designation, which is why that itinerary is inquire-only with a hard screen and no published price.
