Little Cayman is the least developed of the Cayman trio. With a resident population of less that 170, most of Little Cayman remains uninhabited. Only 10 miles long and a mile wide, it still offers that rare combination of sun-blessed solitude, glistening beaches and miles of untouched tropical wilderness. Here, shy iguanas and rare birds outnumber humans. Exceptional fishing can be done on Little Cayman, where bonefish, small tarpon and permit, particularly in South Hole Sound lagoon, challenge anglers looking for light tackle action along the coast. The 15-acre Tarpon Pond is always filled with small, but feisty, gamefish. Little Cayman also has the largest known breeding colony of the Red Footed Booby (5000 pairs) and only breeding colony of Magnificent Frigate Birds in this hemisphere, the country's first RAMSAR site, the 203-acre Booby Pond Nature Reserve, now under National Trust protection. Groundbreaking took place on 22 July, 1995 for a the Little Cayman Trust House, a Caymanian-style building overlooking the rookery, which opened in late 1996 and serves as the headquarters for Little Cayman National Trust activities. It also provides an observation deck with high-powered telescopes for year-round viewing the sanctuary's bird life. Little Cayman now has its own museum, located across from the Booby Pond Nature Reserve. Little Cayman also has a resident indigenous Little Cayman Rock Iguana population estimated at 2,000.
