The island of Fernando de Noronha can only be reached by connecting flights passing through Recife or Natal. Before entering the island, visitors must pay an "environmental preservation tax", which is calculated based on the length of the stay. Although the tax can be paid at the airport, it is best to do it in advance online.
The workshop will be held at the auditorium of the TAMAR museum.
