A linear walk of 7.5 miles including 1,600 feet of elevation overall. Start Point: Snowdonia Parc Pub on the A498, Waunfawr, Caernarfon, LL55 4AQ. Map References: SH 52664 58825 or Lat: 53-66210 Lon: -4.202379
A pub at the start and the finish coupled with free parking and a short train journey, makes this route a walk of convenience with plenty of scope to stretch the legs in-between. Much of the climb is at the start of the walk, heading up to the point where walkers bound for Snowdon separate from those heading towards Llanberis along Telegraph Valley. The area is named after the first Marconi long-wave transmitting station in Britain, the remains of which are still in situ. Good clear paths throughout, requiring only a modest amount of navigation towards the end of the walk as the Slate Trail leads one back to the start through areas of rough pastureland and the outskirts of Waunfawr. Evidence of the slate industry is strong across the landscape, with the Dinorwic quarry clearly visible above Llanberis and Llyn Padarn.
The origins of the Welsh Highland railway – the oldest railway company in the world – can be traced back to the Nantlle horse-drawn railway in 1828 connecting the slate quarries at Nantlle with Caernarfon, a distance of about eight miles. It was converted into a standard gauge railway in the 1860s. Eventually the line was developed to reach Portmadoc, a journey of 25 miles from Caernarfon, where it then connects to the Ffestiniog line. The romance of the steam and the rattle of the carriages provides a historic atmosphere which feels completely fitting to Snowdonia’s heritage, and the route passes through some spectacular scenery.

Cross over the bridge to the railway platform. Take the train to the SnowdonRanger. Note: this is a request stop so be sure to inform the guard. Leave the train at the Snowdon Ranger stop, then cross the train track to join the Snowdon Ranger path. This is clearly denoted as a stone track passing behind some farm buildings and then zig-zagging all the way up to a distinct fork.
Turn left towards Llanberis. Pass through the gate and, keeping Snowdon to the rear walk straight on as the route descends gradually through Telegraph Valley; until after the 4 mile point you reach a single-track road.
Turn left. Continue up to a stile and follow the well-defined path as it climbs towards the disused quarry by Donen Las, Groeslon.
Walk between the slate heaps on a stone track which changes to a single-track road heading down towards Waunfawr. Look for a finger-post on the left at Caer Corlan , also signed for the Slate Trail (yellow arrow) and the North Wales Pilgrim’s Way.
Walk along this permitted driveway and after the two dwellings pass through the gate and turn right at the Slate Trail sign. Continue to follow the yellow arrows.
As the path descends, look for a Slate Trail post to the right and pass over a wooden bridge via two metal gates into rough pastureland. Keep straight on with the stone wall to the left. At the single-track road turn left downhill.
Pick up the yellow arrows again, taking a right turn down a footpath through more rough pasture, passing through kissing gates and the rear of some properties to arrive at the junction of several driveways.
Go straight on, picking up the North Wales Pilgrim’s Way sign by the footpath. At the single-track road, turn right for a short distance towards some properties before taking the footpath on the left. Turn left at the end of the path and after a short distance along the main road, the Snowdon Parc is on the left.
