Small village, no cars, locals use donkies or horse for carrying heavy items, nice beaches, dense rain forests, quiet at night, some entertainment on fri/sat nights..
Close to town, on Boca da Barra beach, Vila da Barra seems to be the only place to stay with comfort. The other beach front pousadas are quite basic. There's one uphill from Tassimirim beach supposed to be nice, but you hsve to walk up hill in rain forest.
The best beach is supposed to be Moreré, but far from the village, I didn't get to explorer.
This place is for people who want to be with nature, and enjoy peace. I've met a German who holidays here every year because of nature, beautiful beaches and not many people around.
Tips for other travellers
To get to Boipeba, you can fly from Salvador, but limited scheduled flights in winter,
or take a speedboat transfer from Valencia. Or an hour car transfer from Mirro de San Paulo to the bank opposite Boca day Barra beach of Boipeba, then a 10 minute boat transfer.
During winter season, it rains often, but usually not the whole day, and still warm during the days, water is warm enough to swim. Be aware, during raining season, the wayer at Boca da Barra beach is not not clear being located where river joins the ocean.
