I'm in the early stages of planning a London to Rio flight and then spending a week or a bit less there. Then I want to head to either Itacare or Florianopolis.

They are both plane rides away from Rio and I will need to book those in advance. www.voegol.com.br and www.tam.com.br will help in that regard.

If you a uk citizen here are the entry requirements currently http://www.brazil.org.uk/tourism/visasvaccinations.html

Where to stay in Rio ?

Surfing Information Florianópolis

Brazil Surf Camp
For 13 days with all inclusive status these guys charge a single traveller
Price per person in an private room: R$ 4.995,00 and this is about 1665 pounds.

"A taxi or a driver from the hotel to lagoa center coasts around R$ 15,00 and you can order one any time."

Checkout the sunset backpackers as it is well documented as a good place to stay and a friend of mine recommends it. They have surf equipment for you and there is some capoeira.

Information on Itacare
You will not find so much online that is in English just yet but the various tour options are staggering in this region. It is an area of natural tropical beauty with amazing beaches and waterfalls. There are all kinds of tours from kayaking to ziplining, surf schools and more..
