Lisbon to Buenos Aires
This nineteen-night transatlantic voyage aboard Le Boréal links Europe with South America. From Lisbon you sail via Gran Canaria and several sea days across the Atlantic to Buenos Aires. The days at sea are shaped on board by lectures, French cuisine and the premium all-inclusive concept, while arrival at the Río de la Plata marks a true change of worlds.
Route highlights
- Lisbon: Atlantic capital on the Tagus with the Belém Tower and Jerónimos Monastery, start of the crossing.
- Gran Canaria: Canary Island with Las Palmas, the last European call before the open Atlantic.
- Atlantic crossing: Several calm sea days between Africa and South America, with lectures and lounges on board.
- Buenos Aires: Argentine capital on the Río de la Plata, defined by tango, Belle Époque architecture and La Boca.

Lissabon · Embarkation
Built on seven hills, Lisbon blends a southern European sense of life with a great history of discovery. From the Tower of Belém, Vasco da Gama and other navigators set out into the unknown - yellow trams and the melancholic Fado still tell the tale today.

Las Palmas de Gran Canaria, Kanarische Inseln
Las Palmas is the capital of Gran Canaria and the largest city in the Canary Islands. The city beach of Las Canteras, the colonial Vegueta quarter and the Casa de Colón recall Christopher Columbus's stay before his Atlantic crossing.
