Costa Rica is famous for its abundant wildlife, beaches, and volcanoes. This tropical country is washed by the Pacific and the Atlantic oceans. The best time to visit Costa Rica is during the dry season from November to April. Early November is the time for Dia de Los Muertos celebration and La Ruta de Los Conquistadores, a challenging mountain bike race. The dry season promises prime surfing conditions on the Caribbean coast and good weather for trekking to Poas and Irazu volcanoes. Don't miss out on the "Festival of the Diablitos" in late December, which celebrates the victory of Boruca tribe over Spanish colonisers. The period from May to October brings so-called 'green season' with afternoon rain downpours and lower rates. In July and August the clouds get thinner, whales cross the Pacific waters on their way from Antarctica, and surfing conditions on the Pacific coast are just right.
