The Amazon and Orinoco headwaters
35% of Colombian territory is in the Amazon basin (known to the Colombians as 'Amazonia'). Leticia is the state capital and gateway for connections to Brazil and Peru. Nearby are several jungle lodges. Sadly Orinoquia is off-limits for the moment to international tourists, the headwaters of the various tributaries of the Orinoco cross vast plains, or Llanos, covering 20% of the country. Serrania de la Macarena in the south-west of the region has a particularly wide biodiversity due to its range of habitats.
