• Welcome : GeoMôn is a Global Geopark – this means it is recognised by UNESCO as having world-class geoheritage – and it embraces the whole of Anglesey / Ynys Môn.   We are one of over 200 Geopark sites around the world and more recently recognised as one of the top 100 geosites in the world!  The name GeoMôn is a combination of ‘Geo’ for all things geological /geographical / environmental and ‘Môn’, the Welsh language name for Anglesey. Whether you are a geologist or simply enjoy natural beauty and landscape, our coastal footpath will show you our fantastic geology and varied scenery, from wide sandy beaches through rocky coves to spectacular cliffs.
