We are delighted to announce that we have appointed a Geopark Development Officer to expand our connections with local businesses and communities – watch for further news.

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 visitor centre (free to visit) is now closed for the winter but watch out for our list of guided walks?

Use the headings above (on a desktop) or scroll down ( on a mobile device) for major links to sections on geology, heritage, activities etc

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
