THE AMAZON:
The Amazon rainforest is the worlds largest biological reserve. It contains one-third of all living species on the earth and is crossed by 10 of the world's 20 largest rivers, including the River Amazon (the largest river in the world). The usual base for trips to the Amazon is the city of Manaus , where numerous tour operators can arrange anything from standard day trips to month-long expeditions to more remote areas. It is best to hire a local guide (trips without guides are only allowed on certain trails). During the rainy season (February to April), the flooded rainforest can be explored by boat or canoe. Several jungle lodges and hotels offer ecotourism packages, though many of these tend to be expensive. River cruises to the so-called ‘wedding of the waters', where the clear waters of the Rio Negro meet the muddy Amazon, are popular. For information on wildlife, see the Resorts & Excursions section.


HIKING AND JUMPING:
The best time for hiking and climbing is from April to October. Rio de Janeiro is the centre of Brazilian rock climbing: over 300 climbs can be reached within 40 minutes from the city centre. There are many great hiking trails in the national parks and along the coastline. The Iguau Falls on the Parana River near the junction of Brazil , Argentina and Paraguay is one of the world's greatest waterfalls, with 275 cataracts. Boat trips to the falls from Rio are available and take two days. Good aerial views can be enjoyed from a helicopter tour of the falls that can be booked on location.


WATER SPORTS:
Brazil is one of the worlds top surfing destinations. The best places to surf in Brazil include Joaquina Beach (near Florianópolis in Santa Catarina state, which hosts the annual Brazilian surfing championships); Saquarema (in Rio state); Búzios (a chic resort area on the Cabio Frio Peninsula ); Itacoatiara ; and a string of beaches near Rio de Janeiro .
