Manhattan of the Seas

Three Sisters, with its several towering pinnacles and columns, may have you believe you have been transported to Manhattan. But look around, and you will see that the only traffic here is the denizens of the reef going about their business.

The Conolly Sisters Legacy

The three prominent pinnacles were named for the Conolly sisters of East End. Agatha, Bertha, and Cleo. Regulars of the Morritz Tortuga Club may be familiar with Cleo for her fabulous cooking!

Journey Through the Canyon

A long and narrow yet accessible and open-topped canyon starts close to the pin and leads directly to the first pinnacle. A dramatic start to the dive as the passage opens to a view of a looming column of rock. Spend a little time admiring the view before heading west and arriving at the second pinnacle in just a few minutes. The third pinnacle sits just a few minutes further and is especially impressive when approached from at least 70 feet deep, as it has a pronounced lean that is most noticeable when viewed from deeper. Cayman's version of the leaning tower of Pisa, just without the touts selling tacky trinkets!
