Bring USD cash!
Bring USD cash for all your expenses.If you use ATM, credit card or exchange money at the banks, you get the unfavourable rate of BsF 4.30 for one USD. On the black market you get double that amount.Theo was reminded of his visits to the Sovyet Union in the sixties, when the official rate was 1Ruble = 1.10 USD, yet on the black market they gave four Rubles for a dollar.It is like that now (2012) in Venezuela. When Venezuelan citizens want to travel abroad, they are only allowed to take USD 500 in foreign currency. So naturally they are keen to obtain more unofficially, and they readily paid us BsF 8.50 for one USD. That made our trip to Angel falls a lot cheaper!Of course such a deal needs trust from both sides. We sold our dollars to friends of friends. If you don't have such connections, perhaps you should deal while with a group.
