It was a bus tour we just picked up at the dock. It was several years ago now-no beach, just a couple of stops like a look out, the Curacao distillery where they gave you tastes of the various liquors, through the town but I honestly can’t remember what else. We had originally booked a private snorkel tour which was cancelled because of rain so picked this one up. (He also gave us all a bottle of beer or water to drink on the bus)!
For beach ones you’d have to google & dig deeper I think.
