Where the Waterfall Vanishes
Deep among the trees of Belmore Forest lies one of the Geopark’s most atmospheric natural features, Pollnagollum Cave. From the viewing platform, watch as a waterfall tumbles approximately 12 metres over a limestone cliff before disappearing dramatically into the darkness of the cave below.
But the story doesn’t end where the water disappears.
The stream continues its journey underground for around 1.5 km before emerging again on the northern bank of the Aghanaglack River. It is a wonderful example of the hidden drainage systems found within Fermanagh’s limestone landscape, where an extensive network of caves lies beneath the forest and surrounding countryside.
Pollnagollum Cave was used as a filming location for the television series Game of Thrones, adding a touch of screen magic to an already dramatic landscape.
