Overview
Cuilcagh Lakelands Geopark (often called the Cavan Lakelands Geopark) is one of only four trans‑national UNESCO Global Geoparks in the world. Spanning 1,741 km² of public land, it links the rugged uplands of County Fermanagh with the drumlin‑strewn lakes of County Cavan – a region proudly nicknamed the “Lakeland County” for its claim of 365 lakes, one for every day of the year. Highlights include the subterranean Marble Arch Caves, the Instagram‑famous Cuilcagh Boardwalk Trail, the relict Cavan Burren Park, and the myth‑laden source of the River Shannon at Shannon Pot.
History & Background
Designated in 2008 as the world’s first cross‑border Geopark, the area gained UNESCO Global Geopark status in 2015. It is jointly managed by Fermanagh and Omagh District Council and Cavan County Council, reflecting a collaborative approach to protecting a shared natural and cultural heritage. Human occupation stretches back to the Neolithic, with megalithic tombs such as the Calf House Dolmen and Bronze‑Age cairns perched on Cuilcagh’s summit. The Plantation of Ulster left a legacy of fortified houses, the most striking being the well‑preserved Monea Castle. Medieval sites such as Clough Oughter Castle overlook Lough Oughter, while the River Shannon’s source at Shannon Pot has been a place of pilgrimage and legend for centuries.
