- South America ↗Above 2,500 m (Bogotá, Quito, Cusco, La Paz) keep the first day light; sleep lower where you can (Sacred Valley before Cusco) and descend if headache comes with vomiting or confusion.
- South America ↗A yellow fever certificate is required on arrival in French Guiana, and asked for on some routes into Bolivia, Paraguay, Suriname and Guyana, or when arriving from Amazon areas — vaccinate at least 10 days before travel and carry the card.
- South America ↗Overnight buses are the norm in Argentina, Chile and Peru, but pick top-tier companies and keep valuables on your body; on-board thefts from overhead racks are the common loss.
- Argentina ↗Check entry rules for your passport with Argentina's National Migration Directorate (Migraciones) or an Argentine consulate before booking.
- Argentina ↗Since April 2025 the official, MEP and street ('blue') dollar rates sit within a few percent of each other; a foreign card is usually the best-value way to pay, while ATM withdrawals carry high fixed fees. Rules have changed often — check before you fly.
- Argentina ↗Patagonia (El Calafate, El Chaltén, Ushuaia) is a November–March trip; in winter many services close and hiking is limited.
- Argentina ↗Since August 2026 non-resident foreigners must show insurance or pay for non-urgent care at nationally run public hospitals, and Buenos Aires City, Mendoza, Salta, Jujuy and Santa Cruz charge visitors for scheduled care; emergencies are still treated. Travel with medical insurance — check the current rules.
- Mesopotamia ↗Iguazú Falls has an Argentine side (walkways, more trails) and a Brazilian side (panoramic views); both need a passport and a separate ticket.
- Mesopotamia ↗Esteros del Iberá is reached by long gravel roads; most visitors join guided tours from Colonia Carlos Pellegrini or Mercedes.
Misiones is famed for Iguazú Falls on the Argentina‑Brazil border and the four UNESCO‑listed Jesuit mission ruins; combine nature and history with a short stay in Puerto Iguazú and a few nights in Posadas.
