The town of Llanfair Caereinion is built upon the site of an old Roman fort, in the valley of the River Banwy. There are several high street banks, a Post Office, two supermarkets, and three pubs. There is a river walk leading to an Arboretum containing over 25 different species of British trees, an ideal place to explore before jumping on the narrow gauge heritage steam railway that runs 8.5 miles west to Welshpool.
