Travelers from all EU countries, the US, Canada, Australia, New Zealand, South Africa and many other Latin American countries do not require a visa to enter Chile for less than 90 days. They will be issued with a Tarjeta de Turismo (tourist card) upon arrival in Chile. It is important that you keep it for when you leave the country. Additionally, Australian and Mexican citizens will be charged a Reciprocity Fee.
To enter Chile, you must hold a passport that is valid for a minimum of 6 months after your travel dates.
Consult with your local embassy or consulate for country specific information regarding the visa regulations.
