Go 1,000 feet below the surface in a real 5-person mini-submarine – no scuba gear required. The Curasub, operated by Substation Curaçao, takes you to depths unreachable by divers, where bizarre deep reef creatures and shipwrecks lie. A pilot guides the 1.5-hour descent, during which you peer through a huge dome window at rare fish, ancient coral formations, and maybe a shark or two. It’s a once-in-a-lifetime expedition into the deep ocean blue (with a price tag to match, but absolutely bucket-list worthy)
