Discover Anglesey’s world-class geoheritage – a UNESCO global geopark of geological wonders.   Anglesey has such special geology that it is recognised by UNESCO as a “global geopark” – a place where the rocks, fossils, landscapes are world-class. Whether you are a geologist or simply enjoy natural beauty and landscape, Anglesey is one of over 200 Geopark sites in 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. Our coastal footpath will show you our fantastic geology.  To help you explore, we have produced  free trail leaflets for you to download and written several informative guidebooks for you to purchase from our ONLINE SHOP

Myfanwy – our very own mammoth is the oldest mammoth in the UK.  Follow her story here

We are pleased to announce that our visitor centre, The Watch House in Amlwch Port, is open for the summer season. Full details here  Visitor Centre 

We are very grateful to Jane Adlam who has donated GeoMôn a large collection of geology books, in memory of her late husband Keith Adlam. Both were BGS staff, working in Edinburgh and Keyworth – her specialty was seismology and Keith’s was sand and gravels. These will be added to our growing library.
