One other option is to ask for Tony (Antonio) as a buggie guide in Cumbuco. Everyone knows him so just ask. Great reputation. He can take you up to Jeri find good and cheap pousadas, (and keep you safe) at a reasonable cost. The buggies break down a lot so best to have a guide who can fix them. What he does is follows you down the coast while you kite! then shows you where to eat and stay every night! Its so fun. The buggies are a an adventure and hard on the back, but you see brazil from the water not the road. He was worth every penny.
Renting a car or 4x4 and traveling is a recipe for getting lost, possibly robbed. Some towns are very safe, others not the least. Cumbuco is very safe, but as you travel north, there is much more poverty and no jobs, so get a guide.
Jeri is pricey but fun, Paracuru was great, Prea has great waves, some tourists were robbed in Pecum when we were there. The Caiupe lagoon is TINY and crowded. Don't bother. Also don't listen to Toby, he has a vested interest in the place. The wind is on everyday, but often the waves are messy in Cumbuco. Very little flatwater unless you travel. Also youll hear how it gets windier to the north. Sometimes true. Also like anywhere, when its 9m its gusty.
