Sombrero, or Hat Island as it is often called, is a
flat island approximately 95 acres in size and about 40
miles from the main island. Sombrero has a long
history of phosphate mining (also referred to as “Guano
mining”) that has left the surface marred with craters
up to 10 meters deep.
island is also the home of a lighthouse that marks the
shipping lane between the Atlantic Ocean and Caribbean
Sea known as the Anegada Passage. On January 1, 1868,
the first light glowed from the Sombrero Lighthouse.
Over the years, improvements and replacements were made
to the structure to deal with advancements in technology
and damage from hurricanes. The lighthouse and related
buildings were manned until 2002 when the structure was
replaced by an automated tower.

2008 by Birdlife International for a number of breeding
seabird colonies and an endemic ground lizard.
