After perfecting your tango in Buenos Aires, we sail to Punta del Este, known as the St. Tropez of Uruguay for its upscale resorts and casinos. After a day at sea, visit Argentina's Puerto Madryn, home to whales, penguins, and elephant seals. Next come the captivating Falkland Islands and then we sail to Ushuaia, located at the southernmost tip of South America. We spend two nights in remote Punta Arenas, gateway to Antarctica and some of Patagonia's most thrilling sights. Two days cruising the spectacular Chilean Fjords follow, before we arrive at the otherworldly landscapes of Laguna San Rafael National Park. Our next stops are Puerto Chacabuco, jumping-off point for the Aysen fjords; Castro, remarkable for its multi-colored stilt houses; and Puerto Montt, capital of Chile's Los Lagos region. A day at sea offers time to refuel before reaching Valparaiso for two nights in the Chilean port city known for its UNESCO-listed center, multicultural vibe, and street art. We continue to explore Chile at Coquimbo, beloved by locals for its beaches, and Iquique, another sandy stunner that also has a fascinating museum brimming with pre-Columbian artefacts. Peru is next, with stops in Puerto San Martin, Callao for the vibrant capital Lima, and Salaverry in Peru, home to the largest adobe citadel in the Americas predating Spanish rule. Now to Guayaquil in Ecuador, where iguanas roam - a taste of what lies just across the waters in the Galapagos Islands - and then Fuerte Amador, where an overnight stay offers plenty of time to explore nearby Panama City. Next comes the thrilling experience of cruising the Panama Canal, one of the great man-made wonders of the world. We're bound for the beach in Puerto Limon, Puerto Rico, before a relaxing day at sea takes us to Roatan - this tiny island has the second-biggest coral reef in the world. Explore Mayan treasures in Santo Tomas, Guatemala, and Belize City. Now we cross to Mexico for an overnight in Cozumel, famed for its powder sands and duty-free shops, and a day in Progreso, for tequilas on the malecon and souvenirs in the handicrafts market.
