International Geodiversity Day 2026

This International Geodiversity Day, we’re celebrating the incredible geodiversity that lies right on our doorstep in Cuilcagh Lakelands UNESCO Global Geopark.

The theme of this year’s event, “Geology on Your Doorstep”, reminds us that some of Earth’s most fascinating stories can be found in the landscapes around us. Here in the Geopark, those stories span more than 600 million years of Earth history.

Across the Geopark, the rocks beneath our feet record an extraordinary journey through time. From some of the oldest rocks in Ireland, through ancient oceans, tropical seas, river deltas and mountain-building events, to the glaciers that helped shape today’s landscape, the Geopark preserves an exceptional geological record within a relatively small area.

This rich geodiversity gives rise to the diverse landscapes that make the Geopark so special. Limestone lowlands, sandstone uplands, lakes, rivers, caves, waterfalls, glacial landforms and peatlands all tell different chapters of the same story, revealing how geological processes have shaped the landscape over hundreds of millions of years.

Geodiversity is much more than rocks. It influences our biodiversity, water resources, cultural heritage, history and sense of place. It shapes the habitats around us, the routes taken by rivers and even the landscapes that have inspired generations of communities to live, work and explore here.

Perhaps most remarkably, the story is still being written. While the Geopark’s rocks preserve evidence of an ancient past, geological processes continue today as rivers shape the landscape, peatlands develop, and underground cave systems slowly evolve beneath our feet.

From ancient rocks formed over 600 million years ago to landscapes and cave systems that continue to develop today, Cuilcagh Lakelands UNESCO Global Geopark offers a window into Earth’s story unlike anywhere else.
