Cuba is an island nation in the Caribbean.
Hitchhiking works extremely well in Cuba.
Pitching a tent or sleeping in a sleeping bag on the beach is strictly forbidden in Cuba. But if you don't have a sleeping bag or tent (it is warm), you can still get away with it. There are a lot of mosquitos. If you choose to use a tent or sleeping bag, be very discreet as there are many police in Cuba. It is best is to pitch our tent when it is already dark and leave early in the morning.
Casa particulares are like bed and breakfast and cost 20-30 CUC per night. They have a blue anchor on the housedoor. It is usually very simple but clean.
All inclusive hotels can be a luxurious experience for hitchhikers if you really need something to eat (and drink). You can smuggle yourself in easily if you carry coloured straps with you: check out what colours the tourist wear on their arms do the same. Enter the hotel via the beach, check some room numbers (if you are asked for a room number) and eat as much as you can. Some hotels don't even have straps for the guests. If you try to do this, try to look like a Canadian package tourist and not a low-budget traveller, otherwise you might get caught.
In touristic places you will be asked very often if you want to eat in a paladar, which is a private restaurant in a private residence. These places are mostly better and cheaper then in an official restaurant. But always choose the restaurant on your own, and don't go with anyone who asks you, because you may be forced to pay for their bill.
A typical meal is rice with beans and some meat. For most Europeans it is not very tasty. Keep some salt and pepper with you.
Markets don't have a good choice of products. A good idea is to buy fresh fruits from the street.
Don't drink tap water in Cuba.
Cuba has a tropical climate with a dry season from october to april and a humid season between may and september. In summer it will be between 30 °C and 37 °C at daytime but with very high humidity which really makes you sweat. During summer the sun is strong so do something to protect yourself (woman sometimes take an umbrella, on the road people often wait under bridges or in small bus stop houses). Also heavy tropical rainfalls with local flooding can occur at any time, be prepared. Also carry enough water with you.
