Hafod Ruffydd is a location on the Welsh Highland Railway. This is the 'summer residence of Gruffydd,' who kept cattle in the 1600s. Several local farms kept cattle - no doubt the Welsh kind which come red in the dominant form, or black in the recessive; either is exceedingly good eating.

Y Garn is the first summit on the traditional northeast to southwest traverse of the classic Nantlle Ridge. The summit is most notable for the excellent vantage it provides towards the striking north ridge of Mynydd Drws-y-Coed – an enticing line. From here, it's a grade one scramble to its neighbouring summit.
