Breaking News : We are proud to yet again be finalists in the prestigious Go North Wales Tourism Awards. This year we have reached the finals in two categories.

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.

NEW : Series of geo-themed talks announced

Join us for our next online lecture by Dr. Libby Robinson, who will be walking us through some classic concepts from ocean geochemistry and what evidence we have for ocean evolution over geological time, focusing especially on ocean anoxia. This talk draws on work she carried out during her PHD, and with her guidance we will travel across the Atlantic to the drylands of Colorado to learn about one of the greatest deoxygenation events in Earth’s history, and how the Western Interior Seaway bucked this trend. What can this deep time puzzle tell us about ocean deoxygenation happening today?
