Dean's Blue Hole is the deepest underwater sinkhole in the world. It is located in a bay to the west of Clarence Town in Long Island, Bahamas. The hole is 663 ft (202 m) deep, and is filled with seawater. Surrounding it is sandy sea bottom. As the sea here is usually very clear, the blue hole appears as a dark blue patch in the sea.

Dean's Blue Hole is under 6 m (18 ft) of sea. It is visible from the surface, due to clarity of the seawater. The walls of the hole are almost vertical. There are no marine life within the hole except for an occasional shark.

Although Dean's Blue Hole is regarded as the deepest underwater sinkhole, there are other water-filled sinkholes that are deeper, including Zacatón (335 m, 1,099 ft) in Mexico and Pozzo del Merro (392 m, 1,286 ft) in Italy. It is however the deepest with its entrance under the sea.

About this website



Dear visitor, thank you so much for reading this page. My name is Timothy Tye and my hobby is to find out about places, write about them and share the information with you on this website. I have been writing this site since 5 January 2003. Originally (from 2003 until 2009, the site was called AsiaExplorers. I changed the name to Penang Travel Tips in 2009, even though I describe more than just Penang but everywhere I go (I often need to tell people that "Penang Travel Tips" is not just information about Penang, but information written in Penang), especially places in Malaysia and Singapore, and in all the years since 2003, I have described over 20,000 places.

While I try my best to provide you information as accurate as I can get it to be, I do apologize for any errors and for outdated information which I am unaware. Nevertheless, I hope that what I have described here will be useful to you.
