The beautiful Isle of Anglesey lies off the west coast of Wales, UK. It is Wales’ largest offshore island (715 sq km) and has over 200 km of spectacular coastline with rocky headlands and extensive sandy beaches attracting millions of tourists for seaside holidays, bird watching, climbing, coast steering, walking, kite surfing and swimming. The amazingly diverse geology is exposed along the coastal footpath.

Conservation, Education & Tourism

The island is renowned for its diverse tectonic geology. Brilliantly coloured Precambrian (about 800Ma) 'pillow' lavas (erupted on the deep ocean floor with a characteristic shape) and deep ocean sediments are exposed at the western end whilst on the north coast is the world type locality for melange containing blocks of limestone with 800 million year old fossils. The remarkable folds and faults of South Stack date from the Cambrian period (520Ma). Carboniferous limestones deposited about 350Ma, crowded with fossil coral and shells show how ancient ice ages, sea level changes and plate movements affected the world long ago.

Visitors to the Geopark can find much to see and do. There are many geotrails along the very popular coastal footpath whilst the Beaumaris trail guides the visitor around the town showing how many different rocks have been used for building castles, churches and houses.  Archaeological sites show how man has lived here from the Mesolithic period about 7000 years ago, mined copper in the Bronze Age and built the best designed Edwardian castle.  Famous local people include Sir Kyffin Williams R.A., a renowned local artist was a founding member of the Geopark; his great uncle, Sir Andrew Ramsay, was the "father of Welsh Geology". Many local artists, photographers and craftspeople thrive on the beautiful scenery of the geopark.
