Pont Croesor is a railway halt in Wales, on the Welsh Highland Railway, which runs through the Snowdonia National Park from Caernarfon to Porthmadog. It is located on the section between the stations of Hafod y Llyn and Pen-y-Mount Junction. Originally, as part of the Croesor Tramway, there was a siding at this location but no station. When the WHR was initially built in 1923 a small halt was provided; however, this closed with the railway in 1936 and all trace of this was removed when the line was lifted. It opened to timetabled passenger services on 8 January 2011.
