on the west side of the canal do bacalhau there is the marambaia sandbank, with an extension of 42 kilometers, which is separated from the mainland by the channel.

with the marambaia sandbank is the marambaia island, which is not actually a fully disconnect island but receives this title anyway, home to some of the rarest ecosystems of the atlantic forest (mata atlântica).

there are not many activities undertaken on the canal, or in the region, however, yachting is one of the few pastimes found on the canal, whilst it is also sometimes used as a shipping lane.
