Caribbean Netherlands is Bonaire, Saba and Sint Eustatius. They are special municipalities of the Netherlands, they use the US dollar, and they are not a day trip from Amsterdam. Almost everyone who books here is coming for Bonaire. Saba and Sint Eustatius are different islands, different airports, different weeks. Do not fold them into a Bonaire itinerary.
Bonaire diving and Klein Bonaire
The west coast is the working reef. Sites sit close enough to shore that many operators run scuba from a truck and a yellow rock, not a liveaboard. Snorkelling uses the same leeward water. Klein Bonaire is the uninhabited islet you reach by boat when the sea allows. East-coast wind can chop the crossing even when Kralendijk looks calm. You'll need the island nature fee for the marine park. How it's collected is on the listing or at the shop.
Lac Bay, the park and land days
Windsurfing at Lac Bay depends on the trade wind, which is often stronger in the first half of the year. Kitesurfing has its own designated spots, not the same bay as the windsurf crowd. Washington Slagbaai National Park is the north: cactus, goats, and hiking or a snorkel stop if you start early and carry water. Flamingos show up around the salinas when the water suits them. That is not a timetable.
Where to base yourself
Kralendijk, or a west-coast dive lodge with a truck, is the useful base. You can reach most shore sites and the Klein Bonaire dock without changing hotels. Lac Bay is a separate outing. The park is a full morning, not a sunset add-on after two tanks. Aruba and Curaçao are different islands. They are not suburbs of Bonaire.
Booking and getting started on adventuro
Intro dives, snorkel trips and many shore-dive packages are beginner-friendly if you swim. Certified walls, night dives and stronger windsurf sit at improver and advanced. Open the Book here tab for live dates. Rental trucks and marine-park spots are the things that get tight, not the island itself.
