1. Venezuela is a cheap destination for foreigners at the moment… as long as they are willing to negotiate in the parallel currency market.
In Venezuela, there’s an (unfortunate) exchange control that prevents the free flow of foreign currency. This creates an official exchange rate and a “parallel” one, that we called black dollar (dólar negro). A dollar-holder traveler can benefit from it: with a handful of dollars, you can get many Venezuelan bolivars, making the country particularly cheap. Though this parallel market is not legal, anywhere in the country you’ll meet people willing to do the exchange. For instance, a meal in a very good restaurant could cost 7.000 bolivares and it represents just USD$7 with the current parallel exchange rate. It’s an extremely expensive meal for a Venezuelan, considering the minimum salary is only 15.000 bolivars monthly. Similarly, spending 6D/5N exploring the Roraima (a must in the country) has an approximate cost of 200,000 bolivares (only USD$ 200 at the black market). Beware that some tour operators require the payment directly in dollars to foreign tourists to go to more remote areas like Canaima and Los Roques.
