Praia da Solidão sits near the far southern end of Ilha de Santa Catarina, beyond the busier beach circuits of Florianópolis. Its name is not just branding: the cove has a quieter, more natural feel, with forest behind the sand and open Atlantic water in front.
Bring what you need and treat it as a low-key beach outing rather than a serviced resort strip. The area also works well for a walk toward the small Cachoeira da Solidão, making it a good choice when you want a beach day with a little movement built in.
