Dive-site story
Grand Canyon is a volcanic formation within the Sint Eustatius National Marine Park. Ancient basalt lava flows created deep trenches and rugged ridges extending toward the open Caribbean Sea. Sheer vertical walls along these rocky corridors hold deep-water gorgonians, wire corals, and barrel sponges, while pelagic species patrol the outer drop-offs.
