Location

Lagoa do Negro is located in the parish of Altares, within the municipality of Praia da Vitória, on Terceira Island, Azores. The site is nestled in a natural area distinguished by dense cryptomeria vegetation, with the imposing Serra de Santa Bárbara serving as a backdrop and Pico Gaspar flanking it. Its inland position provides an environment of tranquility and isolation, inviting contemplation of the landscape.

A Natural Mirror

This is a modest-sized lake, yet of striking natural beauty. Its waters, classified as oligomesotrophic, are home to specific aquatic vegetation, including species like Littorela uniflora and Isoëtes azorica, which contribute to its ecological uniqueness. The surrounding scenery, characterized by the intense green of the trees and the mountainous formations, offers a serene and inviting atmosphere for those seeking a more intimate contact with Azorean nature. It is important to note that, depending on the time of year, the water level of the lake may vary.

Ecological Richness and Geological Heritage

Lagoa do Negro is recognized for its ecological relevance, especially as a habitat for migratory birds. More than 150 bird species have already been observed in this area, demonstrating the richness of its biodiversity. Thanks to conservation efforts, the lake has been recovering its importance for avifauna, witnessing the return of species such as the white-cheeked terns, after a long period of absence, which highlights the success of environmental protection initiatives.

From a geological perspective, the lake has a deep connection with the island's formation. It is located in an area of lava flow, resulting from the volcanic activity that shaped the Serra de Santa Bárbara. Interestingly, beneath Lagoa do Negro, the Gruta do Natal (Christmas Cave) develops, a set of lava tubes that serve as vestiges of the ancient volcanic eruptions of the mountain range, revealing the complexity of the substratum where the lake is situated.

The Legend and the Name

The name "Lagoa do Negro" (Negro's Lake) carries with it a story rooted in the times of the island's initial settlement. Its origin is linked to an ancient local legend, transmitted orally through generations. This popular narrative confers a symbolic and mysterious character to the place, enriching the visitor's experience with a cultural and historical dimension that complements the lake's natural beauty.
