Lough Carra is a renowned rich limestone lake situated in County Mayo on Ireland's west coast, covering approximately 1,620 hectares. It is a shallow, predominantly spring-fed marl lake, celebrated for its gin-clear, turquoise waters and a calcareous, rocky lake floor. This unique habitat forms part of the Lough Carra/Mask Complex SAC and SPA, supporting a diverse ecology. The lake is famous as a top-rate wild brown trout fishery, characterized by massive insect hatches and free-rising trout. While relatively shallow, it reaches a maximum depth of around 20 meters, and fishing is productive across practically all areas of the lake.
