At the end of a sandbar, surrounded by lagoons and mangroves, this lighthouse dates from 1913. The coastline around here is a popular family excursion (avoid weekends) and there's a play area for kids. Swimming in the calm water, surrounded by islands and inlets, is the main draw, though boat trips can be good for bird- and crocodile-watching.
