About Bonnie'S Arch
Bonnie's Arch is an arch-and-wall dive off Grand Cayman's west side, with a mini wall and cavern framing the main structure. Tube and barrel sponges sit at the base, giving the site a classic Cayman look without pushing it into a deep-wall profile. It is known for easy photography, clear water on calm days, and marine life that ranges from tarpon and angelfish to lobsters, crabs, shrimp, and the occasional ray. Shore access is possible in approved spots, but a simple boat run is often the easiest way to dive it.
