The Devil appeared and agreed to build a bridge in return for the soul of the first living thing to cross it.

[16] The celebrated English author George Borrow wrote Wild Wales (1854), which includes a lively, humorous account of his visit to Pontarfynach.

The George Borrow Hotel, a 17th-century inn where he reputedly stayed, is nearby; it is located between Devil's Bridge and Pontrhydygroeis Hafod Uchtryd.

[17] Tourism to the area increased after the bridge and the Hafod building were featured in the Hinterland TV series,[18] which has been broadcast in numerous countries.

[26] The village is served by one bus route, the 522, which runs between Tregaron and Aberystwyth; there is one service daily in each direction on weekdays and it is operated by Mid Wales Travel.

[27] Devil's Bridge and the hotel building are featured prominently in the opening two episodes of the first series of the 2013 Welsh-language crime noir, Y Gwyll[28] (episodes titled in English "Devil's Bridge" and "Night Music"), shown on S4C and subsequently on BBC4 as Hinterland.
