The Orinoco delta is a vast, intricate labyrinth of waterways weaving through a simmering jungle to carry the waters of the Orinoco to the Atlantic Ocean. The Orinoco Delta - the landmass now known as Delta Amacuro State - has formed over the course of thousands of years as the mighty river has deposited millions of tonnes of sediment into the ocean.

Over the last century alone, some 1,000km² has been added to the delta, which continues to extend into the Atlantic at a rate of 40m per year over its entire 360km coastline. The Orinoco branches off into over 60 caños (waterways) and 40 rivers which diffuse through 41,000km² of forested islands, swamps and lagoons.

Organized tours to the delta are becoming increasingly popular. Day trips can be arranged, but most trips encompass at least one night's stay in the heart of the jungle. Accommodation varies from hammocks under wooden shelters to luxury camps with dining and bar facilities, private cabins, running water and electricity.

The latter are constructed in the same style as the nearby Indian houses and blend in well with the surroundings. From the camps, tourists can take boat trips around the delta to observe the remarkable wildlife, hike through the jungle and visit Warao Indian families.

The delta's rich waters are excellent for fishing, especially for piranha and catfish, and some camps also offer night trips along the river to find cayman and other night prowlers. Tours to the delta can be arranged in most tour agencies around the country; Tucupita and Barrancas have several agencies specializing in delta trips. The main access points to the delta are Tucupita, Boca de Uracoa, Barrancas, La Horqueta and Volcan.
