[3][4][5] El salto de la encantada is a waterfall located in Marías.

Legend has it that an indigenous woman was enchanted with a Spaniard but saddened when a relationship never developed between them.

[6] Marías was in Spain's gazetteers[7] until Puerto Rico was ceded by Spain in the aftermath of the Spanish–American War under the terms of the Treaty of Paris of 1898 and became an unincorporated territory of the United States.

In 1899, the United States Department of War conducted a census of Puerto Rico finding that the combined population of Marías and Quebrada Larga barrios was 923.

Barrios (which are, in contemporary times, roughly comparable to minor civil divisions)[14] in turn are further subdivided into smaller local populated place areas/units called sectores (sectors in English).
