Information about:


The nearest town to ONCA is Rurrenabaque (Department of Beni) with approx. 17000 inhabitants. From La Paz city (the nation’s capital) can be reached overland in 18-24 hours (60-70 Bs) or by air in 50 minutes (400 Bs).

If you choose the overland trip do not use the La Paz bus terminal, you have to leave La Paz from the Villa Fatima informal stations.

Approximate exchange rates are 1 $ = 6,80 Bs or 1 € = 7,9 Bs.

Once in Rurrenabaque you have to hire the service of a “peque-peque” (small motorized boat) that in 15-20 minutes (10-20 Bs) traces the Beni River to ONCA, formerly known as “Prudencio Molina”, near Villa Alcira (request to go to donde viven los gringos).

Another option is letting us know in advance and we’ll pick you up at the internet café Ronaldo`s (located in Rurrenabaque “calle Comercio”); in this case we’ll use our boat and transportation fees run on our own.
