It is an all day long tour, starting with sunlight. It has two stops for snorkeling or diving, and a visit to Cayo Centro, where you'll see the fishermen houses over pillars named 'palafitos', the original iguanas and famouse crocodiles.
For divers it is just the beginning, the bottom goes down slowly further than recrational dive limits. Always rounded with corals, reeffish, turtles, rays, makes this an amaizing experience. Thats the reason this is a Biosfere Reserve.
On the other side of Banco Chincorro, there are rests of somemany wrecks occurs in the area. Mostly still recognizable and with a great archeological worht, but all of them as artificial reef full of coral.
