Beachcombing is a fun activity the whole family can get into. Why not take the young ones to Naufragados Cannons to see what you can spot dotted along the shore?
When you've spent a bit of time at this Florianópolis stretch of coastline, why not make your way to Praia do Sonho, Praia da Pinheira, and Lonely Beach? They're not too far from Naufragados Cannons and also popular with tourists.
