My first trip Bonaire. Amazing. Did shore dives at 23 different sites. Ditto to what Bill said below. I dove this site twice without a guide or permission. To be safe, I dove it on a Saturday and Sunday, when the Cargill operations seem to be closed. The aquatic life is outstanding here. I surface swam to the north most pier, descended, and weaved my way counter-clockwise around the entire structure. Many different specific of large fish and we say a turtle. The highlight for me was when my wife spotted a school of squid, passing slowly beside us.
