Rising near Moelwyn Mawr (2,527 ft) to the west of Blaenau Ffestiniog, the Dwyryd almost immediately enters Tan-y-Grisiau . From there it flows southward through Maentwrog to enter a sizable estuary to the north of Harlech. Salmon and sea trout run up this river with the likeliest period being June through to October. The river also contains trout with the best results being in spring and September. Access for visitors is good.
