Because of its position, it is the first of the Welsh 3000s reached when doing this walk from the northern end. It can be climbed by driving up the small road signposted Aber Falls in the village of Abergwyngregyn, passing the car park for the falls and continuing to a small car park at the end of the road. From there it is possible to take the track bearing left, later turning right to the summit of Drum and continuing along the ridge, or to take the track leading straight on to Llyn Anafon and then climbing up to the ridge between Drum and Foel Fras.
