Around 60% of Lake Titicaca is in Peru and 40% in Bolivia. It is thought to be the largest lake in South America, covering around 8,372 km2 (3,232 sq mi). The lake is navigable by large boats, which means people are able to get out into the centre of the lake to take in the view all around, but is also bordered by many different islands and bodies of land which offer unique experiences to those wanting to visit the area.
The lake has an Alpine climate with cool temperatures all year round. The average rainfall is 61 cm (24 in).
Lake Titicaca and the areas surrounding it are home to a number of rare species of fish, amphibians and birds. One of the most notable species is the giant frog of Titicaca, which can weigh up to 3 kg (6.6 lb) and is unique to the area. Also notable are the sponges that live in its waters and more than 60 species of birds, including the Titicaca Grebe, cormorant, Chilean flamingo, black night heron and the Guarahuaru falcon. Because of the high altitudes and extreme temperatures, there very few mammals, but you may see the vizcacha, wild guineapig, Andean wild wolf, llamas and alpacas.
Activities include visiting the Isla del Sol, an island and fishing community in the Lake, which is good for relaxing and the walking paths that run alongside and to the top of the island; and visiting the man-made floating reed islands (the Islas Flotantes). As well as bird-watching, sailing and kayaking on the lake, there is great hiking in the surrounding areas. Photography and visiting the many archaeological sites are also recommended.
Lake Titicaca has a very high altitude, being around 3,812 m (12,507 ft) above sea level, so visitors may find it difficult to adapt at first.
