The volcano, which is responsible for the formation of the island of Grenada, has been dormant for the last 12,000 years.

Grand Etang Lake lies in Saint Andrew Parish.

[1] The lake is approximately 20 ft (6.1 m) deep and 36 acres (15 ha) in area.

[1][2][3] A local fable says that the depths of the lake are home to a mermaid that lures men to a watery grave.

[4] The surrounding area being a forest reserve and national park, which encompasses the lake and surrounding mountains, has been designated an Important Bird Area (IBA) by BirdLife International because it supports significant populations of green-throated caribs, Antillean crested hummingbirds, Caribbean elaenias, Grenada flycatchers, lesser Antillean tanagers and lesser Antillean bullfinches.
