The $10 tag, and who needs one
Bonaire's nature fee covers anyone who goes into the sea - not just divers, but snorkelers, swimmers, kayakers and freedivers too. Most visitors pay $40 for a calendar-year pass; cruise passengers can buy a one-day version for $10 instead. Children under 13 are exempt.
Pay online through STINAPA's payment portal before the ship arrives. It emails a QR code that you show along with ID, which saves hunting for a sales point on a short call. If a ship excursion includes snorkelling, ask whether the fee is already in its price.
Washington Slagbaai takes cards only
The same fee also covers Washington Slagbaai National Park, all 4,286 hectares of it. If you have not paid in advance, the entrance booth takes credit and debit cards but not cash - the opposite of what many small-island ticket windows expect.
