About Coed Cymerau Isaf

Coed Cymerau Isaf has a long history. The footpath track that runs through the north to the south of the site is a piece of the old Blaenau Ffestiniog to Maentwrog road, which was part of a Roman road later used as one of the area’s main coach roads.

Look out for the stone walls which border the track and old stock pens scattered throughout the woodland.

During the 18th and 19th centuries, oak grown in the area was used for ship building at Porthmadog, where slate was transported from Wales to the rest of the world.
