embarkation from ipanema is quite easy, as palmas is the closest of the cagarras to the shore, however boats to the islands only sail from marina da glória.

since april 2010, this group of islands has been declared a 'natural monument' named monumento natural das ilhas cagarras, or 'mona cagarras'. 

the project ilhas do rio is the first comprehensive and detailed study on the biodiversity of the archipelago.
