Conference Site

LATIN 2008 took place in Búzios, at the Hotel Atlantico Búzios. The hotel is set in front of a beautiful bay called Armação dos Búzios.

Located in a peninsula 180km Northeast of Rio de Janeiro, Búzios is a charming old fisherman city. Today Búzios is an international touristic spot. The beauty of the 26 surrounding beaches, the typical and international restaurants, the famous boutiques, the shows, its daring architecture with old clay roof tiles and rustic wood, its famous Rua das Pedras, the sea with its Olympic wind where Brazilian champions practice, its arid nature, reminiscent of the Atlantic Forest... Everything makes of Búzios a special place.
