Atins is a small village in Maranhão. It shares 2000 inhabitants with its close neighbour Santo Inácio, but these are mostly well hidden. For the slightly adventurous traveller, Atins is a better base camp for Lençois Maranhenses than Barreirinhas, due to the former´s proximity to the dunes. There is also the beach within a few hundred metres.
