Nicaragua—Central America's largest country—offers remarkable diversity: Pacific volcanoes, Caribbean coral reefs, colonial architecture, and vast lakes.
Founded 1524 on Lake Nicaragua's northwest shore. Pastel Spanish colonial architecture, horse-drawn carriages, the yellow Cathedral (Central America's oldest), and the chocolate museum at ChocoMuseo. Base for Isletas de Granada boat tours (365 volcanic islands).
Northwest university city with the hemisphere's largest cathedral (UNESCO), revolutionary murals, Rubén Darío museum (modernismo poet), and access to Cerro Negro volcano boarding (sled down volcanic ash).
Crescent bay with consistent surf, sportfishing, turtle nesting (Jul-Jan), and a backpacker-to-luxury accommodation spectrum. Sunday "Sunday Funday" pool crawl is legendary.
Lake Nicaragua's massive island—Concepción (active, 5,280 ft) and Maderas (dormant, cloud forest). Petroglyphs, waterfalls (San Ramón), Charco Verde reserve, bicycle circuits. Ferry from San Jorge.
Big Corn and Little Corn—50 mi off Caribbean coast. No cars on Little Corn. Snorkeling, lobster, Afro-Caribbean culture (English Creole), zero chain hotels. Fly from Managua (1.5h) or brave the 12-hr ferry.
Nicaragua remains less touristed than Costa Rica—authentic, affordable, and adventurous.
