Moel Eilio is situated approximately 3 miles north-west of Snowdon. It has two subsidiary tops, Foel Gron and Foel Goch. From the elevated start point below Cefn Du, Moel Eilio looks remarkably modest; a mere hill alongside its more impressive neighbours, but then mountains nestled in the foothills of Snowdon will always look like the poor relation. In terms of endurance this route is not to be underestimated as the undulating nature of this cluster of 3 summits requires some stamina. And then, just as you might think it’s all easy going as one heads for home through Telegraph Valley, there’s a final ascent to return to the start point. But the climbing is well worth the effort. On a clear day the scenery is spectacular across the ridge, affording views across to Anglesey and Llanddwyn Island, the Llyn Peninsular, the Rivals, the Nantlle Ridge, and of course, the Snowdon Horseshoe. The way is well defined on grassy tracks or bridleways.
The Telegraph Path is so named after the first successful Marconi long-wave transmitting station, situated on the west-northwest slopes of Cefn Du. The station was in use between 1912 and 1938 and was for many years the most important long-wave station in Britain, handling imperial and international communications. The site closed in 1938 but remains of the buildings are still visible. Historical evidence of the slate industry is another strong feature of this landscape, as nearby Llanberis clearly illustrates via Dinorwic Quarry – a vast scar embedded in the hillside above Llyn Padarn. The first commercial attempts at slate mining in the area took place in 1787. By the late nineteenth century, Penrhyn and Dinorwic were the two largest slate quarries in the world.
From the parking area, turn left along the track past the slate tips until the fingerpost sign directs you onto the main route across Moel Eilio. It’s a well-defined ascent and the summit is denoted by a large stone shelter.
Ignore the ladder stile by the shelter and, following the fence-line on the right, continue downhill in a southerly direction, keeping Snowdon ahead at all times. Take the next ladder stile over the wall, keeping the fence-line to the left.
Tackle the curving ridge of Foel Gron, then take the next stile, keeping the fence-line on the right. The next two stiles crop up almost together forming a right angle, before ascending the final grassy knoll of Foel Goch.
Once over the summit, the track begins to descend the short but steep flanks of Foel Goch. Bear right here on an eroded track heading towards the bottom of the valley where the Telegraph Path skirts the foot of Snowdon.
On reaching the bottom, loop back by turning sharp left along the Telegraph Path, a long bridleway which heads down towards Llanberis and runs parallel to the Moel Eilio trio of hills. Good views to the right of Llanberis, Dinorwic Quarry, and Llyn Padarn.
Follow the bridleway for some 4 miles, passing the Marconi Tower to your left and ignoring all right-hand routes down to Llanberis. Pass through all the boundary gates and stiles and continue straight on as the path begins to ascend.
At the T junction turn left and continue the ascent along the slate trail bridleway until a final kissing gate returns you to the start.
