The Saba National Marine Park encircles the entire island from the high-water mark to 200 feet depth, and it shows. Diving here is among the best in the Caribbean, and the reason is simple: it has been properly protected for decades. The underwater terrain is as dramatic as the island above — volcanic pinnacles rise from the deep, walls drop into darkness, and lava formations shelter an abundance of marine life that has all but vanished from more visited islands.
The signature dives are the Pinnacles, a series of seamounts on the island's northern side that attract hammerhead sharks, nurse sharks, eagle rays, and large pelagic fish. Currents can be strong, so these are not beginner sites — but for experienced divers they rank among the Atlantic's finest. Shallower dives around the south and west of the island suit all levels and are excellent for turtles, eels, and the giant barrel sponges that characterize the reef. Two dive operators are based in Windwardside; either can organize everything from tank rentals to multi-day dive packages.
