The station was opened on 10 October 1867 by the Cambrian Railway Company as Dyffryn.

The redundant track remained in place until 1980 as did a signal that had been converted to a fixed distant.

In 2016, The Welsh Government funded the installation of reinforced glass fibre 'humps' on the platforms to improve access for wheelchair and pushchair users onto and off trains.

[6] The station is an unstaffed halt on the Cambrian Coast Railway with passenger services to Harlech, Porthmadog, Pwllheli, Barmouth, Machynlleth and Shrewsbury.
