Blacklion is an ideal location to explore the Marble Arch Caves Geopark.
“The Marble Arch Caves Global Geopark contains some of the finest landscapes in the north of Ireland. Ranging from rugged uplands, lakes and forests through to gently rolling drumlins, the landscapes of the Geopark represent a complex Earth history dating back as far as 650 million years ago. With evidence of mountain building and destruction; searing hot deserts and warm tropical oceans; and of icy wastelands and water-worn caverns, the rocks and landscapes of the Geopark are nothing short of amazing.”
