There are two currencies in Cuba.
One for the locals, CUP, and another for tourists, CUC. The local currency is worth far less than the tourist one, therefore economically cheaper to use the local currency. 1 CUC equals to 25 CUP. As a tourist, the only currency you can get from the ATM is CUC. To get CUP, you should first get some CUC which you can then exchange for CUP. You should be able to exchange your money at any money exchange.
A Taxi in three ways.
In Cuba, there are three different kinds of taxis. The first kind is the cheapest but slowest, a three-wheel bicycle taxi. These are found everywhere and depending on where you are going can cost you around 5-10 CUP/0.20-0.40 CUC. The second kind is an old school restored Oldsmobile known as a collectivo. That sort of taxi is shared and already has a direction it’s going. If you are roughly going a similar way, then you hop in. These types of taxis usually cost around 10 CUP/0.40 CUC. The third and final type is the most expensive one, mostly because it’s a standard cab used mainly by tourists. Depending on where you are going it can cost you around 5-8 CUC if you are going a relatively long distance it could be more.
However, as with all taxis, always ask the price before stepping in!
Collectivo over buses.
Believe it or not, but you can take a shared taxi to Trinidad, Santa Clara, Varadero or even Vinales instead of a bus. The bus fare to Trinidad is 25CUC, a collectivo to there is 30CUC but will drive all the way to your accommodation. In addition to being more economical, it is also faster. A bus to Trinidad, for example, is six hours versus the collectivo is four.
If you would prefer to take a collectivo over a bus, then you can simply find them outside the bus station.
No SIM Cards.
Although there are SIM Cards for purchase in Cuba, they’re meant for locals and not tourists. There is something called a Wifi Pass instead though. It’s quite simple how it works.
You can go to one of the many ETECSA offices and purchase either a one hour card (2 CUC), three-hour card (5 CUC) or five hours one (7,50 CUC). After which, you can then go to one of the many plazas, parks or squares where you can find the Wifi_ETECSA, on your phone. Once you clicked on it, a window should have popped up where you can type in the username and password given on your WIFI Pass. Voila! You have connected with the world again!
Cuba has an app.
Surprisingly, Cuba has an app with all the tourist info one could ever ask for. Maps, tourist attractions, and etcetera. Also, you can use the whole thing without hindrance offline.
The app can easily be found on both app stores for IOS and Android.
