ブルーホール
Great Blue Hole
A protected marine sinkhole on Lighthouse Reef where divers descend the wall to overhangs hung with ice-age stalactites. Visits are by boat with tour operators, and a daily monument fee applies.
Dive boats tie up to mooring buoys on the rim of the hole, which has no land. Divers follow the steep wall down to overhanging shelves where large stalactites hang, evidence that this was a dry cave when sea level was far lower.
The Belize Audubon Society, which publishes the monument's visitor information, lists diving, snorkelling and wildlife viewing; snorkelling takes place on the coral rim. Sharks and turtles are reported in the area.
環境
Vertical walls and overhanging ledges with stalactites in clear marine water; deep anoxic water with hydrogen sulfide below about 90 m.
コンディション
Open marine site; trips are long boat rides from the cayes and mainland. Hydrogen sulfide and no oxygen below about 90 m (2018 survey).
公表資料からの一般的な範囲であり、現在のコンディションではありません。
設備
No land or visitor facilities at the hole; mooring buoys for dive boats. Half Moon Caye, often visited the same day, has basic visitor facilities.
