Track shown on the 1888 OS map, leading WSW from Hafod y Garreg for approximately 600m over a large field and then on to the common. One branch turns NW for 150m, and another continued WNW for 800m, crossing another track (nprn 510726). This latter section was probably used to gain access to huts and folds further W on the opposite bank of Nant Aberderfel. It survives mainly as a slightly sunken track 2m wide.
