Self-guided geowalk leaflets to download

We have published a range of self guided ‘geowalks’ which are presented here as PDF files to download : there are others  in our publication “Footsteps through Time” (one shown here as an example). If you are following any of our trails please be sure to follow accepted codes on hammering [please don’t], collection of samples [only material already broken off] and general countryside codes [take nothing but photographs, leave nothing but footprints].  Most of Anglesey is a protected site.

Fossil and sample collection

GeoMon UNESCO Global Geopark is signatory to the European Geoparks Network Charter which forbids the sale of fossils and mineral specimens by any of its partner organisations. Fossils are a limited resource, rock exposures are damaged permanently by hammering and collecting, though often there are pebbles on the beaches which can be collected as souvenirs.

The Geopark does not permit the sale of fossils by its partners nor does it promote the collection of fossils from within its boundaries, indeed their collection from many of the sites listed is forbidden by law.  Follow the Countryside Code.

Countryside Code

  • Be safe – plan ahead and follow any signs
  • Leave gates and property as you find them
  • Protect plants and animals,
  • Take your litter home
  • Keep dogs under close control, especially where there are livestock grazing
  • be considerate of other people
  • take nothing but photographs and memories, leave nothing but footprints!

Geology Field work

please follow the  Code for Geological Fieldwork as published by  the Geological Society of London


Our geotrails follow public footpaths or open access land such as beaches.  Nevertheless, you should consider the safety aspects of following any suggested route, such as dressing appropriately for the weather; wearing suitable footwear [some paths are steep and rocky, others can be wet , muddy and slippery]  and taking care over rough ground.  Rocky shores are notoriously slippy in wet conditions.  Consult tide tables before venturing far from shore, for example Llanddwyn Island does get cut-off at high tide.
