The name is so funny, because in Swedish it means the triangle of the girl. I dont think they want me to write *** (c u n t), but it is the Swedish language, but in Portuguese it means like a rope... Languages make it hard some times...
What to buy: You can buy trips and excursions from them.
There are several quaint little stores/shops at Abraao where you can stock up on souvenirs. The purpose of my tip is to tell you that any souvenirs that you buy will be cheaper on the island than in Rio or Angra which surprised me. Any toiletries, etc. will be more expensive but easy to find if you forget anything of if you decide to stay a few extra days as we did.
