Lost Blue Hole

The Lost Blue Hole, off New Providence in the Bahamas, is a lesser-known but dramatic companion to the more famous Great Blue Hole of Belize — a circular karstic sinkhole set in a shallow sandy plain, its interior opening descending vertically from 13 meters at the rim to over 60 meters at the bottom, creating a completely unique topographic dive in the otherwise flat Bahamas shallows. The site's geology and resident marine life make it a highlight of Nassau diving. The dive approaches the hole across a shallow sand plateau, with divers arriving at the rim and descending along the interior wall to 25-30 meters (recreational depths). The wall is completely colonized with hard and soft corals, black coral trees, barrel sponges, and gorgonian fans. Large midnight parrotfish, black groupers, and Nassau groupers are resident along the walls, and occasional Caribbean reef sharks cruise the blue depths of the interior. Marine life is rich and distinctive. In addition to the resident shark population and large reef fish, the hole attracts passing eagle rays, and the sandy approach area hosts southern stingrays, nurse sharks, and conch. The hole itself is a known cleaning station, with cleaner wrasses stationed at the rim to service passing fish. Macro life on the wall includes arrow crabs, banded coral shrimps, and flamingo tongue cowries on the sea fans. The Lost Blue Hole is Advanced Open Water diving due to the depth profile, with dives typically limited to the upper 30 meters of the interior wall. Reached by boat from Nassau dive operators (25-35 minutes). Visibility 20-30 meters in the hole, 15-25 meters on the sandy approach. Water temperatures 24-29°C year-round. Best conditions April through October, though the site dives well year-round. It is a signature dive on most Nassau full-day itineraries and pairs beautifully with the surrounding reef dives and the island's celebrated shark interaction sites.
