This circular walk takes in the spectacular Aberglaslyn Pass, the beautiful village of Beddgelert, the picturesque Llyn Dinas and the old copper mine workings of Cwm Bychan and Sygun and. Leaving the car park, we head up the rough, rocky path through the Aberglaslyn Pass, with the Glaslyn River raging below us. Our trail eases as we pass Bedd y Ci (the grave of Prince Llywelyn's faithful hound) to reach Beddgelert. We continue on a quiet lane and well-made path to Llyn Dinas and then turn to climb steadily up to Bwlch y Sygyn, the high point of the route. A descent through Cwm Bychan past the remains of old copper workings brings us back to the start.
