Mae'r llythrennau enfawr 4 metr o uchder ac 11 metr o led sydd wedi eu gwneud o ddrychau ac sy'n ffurfio'r gair 'EPIC' yn rhan o gam diweddaraf ymgyrch marchnata Croeso Cymru i hyrwyddo Cymru fel cyrchfan antur.  Bydd yn ymddangos mewn lleoliadau ar hyd a lled Cymru dros yr haf.
The giant mirrored letters, reaching 4 meters high and 11 meters wide, forming the word EPIC is part of the latest phase of Visit Wales’ marketing campaign to promote Wales as an adventure destination. It will pop up unannounced at locations across the length and breadth of Wales over the summer.
