Wrth i Gymru ddathlu Blwyddyn y Môr yn 2018, bydd rhan gyntaf y cymal yn dilyn yr arfordir hardd o Fae Tremadog drwy Abermaw a Harlech cyn troi tua’r tir i brofi llethrau serth Eryri, drwy Feddgelert a Betws-y-coed, i orffen ar arfordir y Gogledd ym Mhorth Eirias, Bae Colwyn.
As Wales celebrates the Year of the Sea in 2018, the first part of the stage will track the beautiful Welsh coastline of Tremadog Bay, through Barmouth and Harlech, before heading inland to tackle several climbs as the route crosses Snowdonia, via Beddgelert and Betws-y-Coed to finish on the North Wales coast at Porth Eirias, Colwyn Bay.
