Other North America destinations
Honduras
Honduras combines Copán's Maya sculpture, Bay Islands diving, Pico Bonito rainforest, coffee highlands, and Caribbean coast communities. The best itineraries usually pair archaeology with reef time.
Jamaica
Jamaica is reggae, Blue Mountain coffee, jerk smoke, waterfalls, and a coast that changes character from Negril to Port Antonio. It is culturally outsized and rewards travelers who go beyond resort gates.
Mexico
Mexico is so much more than Cancún. Mexico City's Aztec-plus-colonial layers, Oaxaca's food, Yucatán cenotes and ruins, Puerto Vallarta and Tulum beaches, and Chiapas rainforest.
Nicaragua
Nicaragua links Granada and León colonial streets, volcanoes, Lake Nicaragua, Ometepe Island, Pacific surf, and the Corn Islands. It is one of Central America's strongest backpacker and overland routes when conditions are stable.
Panama
Panama pairs Casco Viejo's old town and Panama City skyline with San Blas islands, the Darién rainforest, and a canal that still feels astonishing when a Panamax eases through.
St. Kitts & Nevis
St. Kitts and Nevis is a small two-island country with fortress history, green volcanic slopes, plantation inns, and quiet beaches. St. Kitts carries the cruise and railway infrastructure, while Nevis feels slower and more intimate.
