Name

The name "Cardona" is believed to come from the last name of a family of lighthouse keepers stationed at the island for many decades. Whatever its origin, the island is now also called " Sor Isolina Ferré" in appreciation and to the memory of the religious woman that dedicated her life to the betterment of the residents of Barrio Playa, of which Cardona Island is a part.

Tourism

The island can be seen from the observation tower on the La Guancha boardwalk and is accessible by private boat. Starting in the summer of 2018, tourists can also board a ferry for a trip to the island. The island offers "a beautiful, nice snorkeling, some trails to explore, and a lighthouse." The ferry trips ceased in January 2020 after a major earthquake struck the area, but restarted six months later. The island is administered by the Puerto Rico Department of Natural and Environmental Resources.
