Clodagh Glen has a steep sided gorge that is lined by ancient ash trees that cling to the steep sides. The water sculpted river valley has a spectacular arch over the river which formed when the cave roof collapsed. The reserve is known for its limestone gorge, mystical caves and beautiful waterfalls.
In the springtime the valley floor is carpeted by bluebells, wood anemones and wild garlic and in the summer silver-washed fritillaries are found besides the path. With a keen eye you may also spot an elusive pint martin and red squirrels!
