Playa Porto Mari is a well-run beach on a private plantation estate near Sint Willibrordus. Its calm water and unusual double reef suit both snorkellers and divers, with straightforward shore access and a dive operator on site.
This is the comfortable Bandabou option: there is an admission charge, along with loungers, shade, showers, and food. Two short nature trails begin near the car park. It lacks the wild feel of Kenepa Grandi, but it is easier for a full beach day.
