Cuilcagh, Mountain peak at County Fermanagh and County Cavan border, Ireland and Northern Ireland.
Cuilcagh is a mountain of roughly 665 meters at the border between County Fermanagh and County Cavan. The landscape features sandstone cliffs, extensive blanket bogs, and diverse habitats for various plants and animals.
The mountain received its name from the Irish term Binn Chuilceach. In 1609 the area belonged to John Sandford during the Ulster settlement before passing to Toby Caulfeild.
The mountain marks the boundary between two regions and contains the traditional source of the River Shannon at Shannon Pot on its southern slope. This location holds special meaning for people who cross and use the area.
A popular hiking route, the Cuilcagh Boardwalk Trail, runs from Legnabrocky Car Park over roughly 6 kilometers with gravel paths and wooden steps to a viewing platform. The trail is fairly well-developed and offers different difficulty levels for various hiking abilities.
Water from Cuilcagh flows underground through limestone caverns before emerging at Shannon Pot on the surface. This hidden network beneath the mountain is geologically remarkable and rarely fully understood by visitors.
