Discover The Geopark

Marble Arch National Nature Reserve (Cladagh Glen)

The narrow-steep sided gorge of the Cladagh Glen is one of the most picturesque sites in the Geopark, as the Cladagh River re-emerges from its underground journey through the Marble Arch Caves. The woodland is a tiny remnant of the ashwoods that once covered much of Ireland, so many of the trees you can see here today are direct descendants of those trees that grew here hundreds of years ago. In spring the woodland floor becomes a carpet of wildflowers and herbs namely bluebells, wood anemone, primroses and celandines. Pine martins, red squirrels and dippers are commonly seen within the reserve – so this is a must see for any nature enthusiast.
