The Ferndale pits are what drew the workforce and their families to the area, and by the 1880s "Ferndale" was well established as a thriving town. With the phasing in of bilingual road signs from the late 1980s onwards, the name Glynrhedynog gradually reappeared and is now the officially designated Welsh language name for Ferndale. The Welsh language is on the increase in Ferndale after the village adopted the English language during the Industrial revolution. A Welsh language school is situated near the park and the school is named after the park's lake, 'Llyn-y-Forwyn.' (The Maiden's Lake)
