In addition to the Lagoa do Negro (lagoon), from this viewpoint it is also possible to observe the trachytic domes, in a rounded shape, that result of the historical eruption of 1761. These domes, named Mistérios Negros, have a vegetation cover that is still very young. For this small lagoon are referenced about 150 bird species. One can also do the Mistérios Negros walking trail (PRC1TER) and/or visit the Gruta do Natal (cove), also inserted in the Serra de Santa Bárbara e dos Mistérios Negros Nature Reserve.
