Marble Arch Caves Global Geopark
Excerpt from www.discovernorthernireland.com:
The Marble Arch Cave complex has good car parking, a souvenir shop, restaurant, exhibition area and an audio visual theatre. The caves are situated in a National Nature Reserve.
Tours of the caves last approximately 75 minutes and are suitable for people of average fitness (comfortable walking shoes and a warm sweater are recommended). Tours of the cave complex start with an underground boat trip, after which your trained guide will conduct you through a variety of cave formations, including the Moses Walk, Porridge Pot and Guardian Angel. Naturally occurring stalactites and stalagmites are also visible throughout your tour.
Both Marble Arch Caves and the nearby Cuilcagh Mountain Park have jointly been recognised as a UNESCO Global Geopark due to the world importance of their geology and landscapes. The site is the only UNESCO Geopark in Northern Ireland.”
