Tryfan Junction from Caernarfon

This little route connects the Welsh Highland stations at Caernarfon, Bontnewydd and Tryfan Junction along easy country tracks. You can divert at Tryfan Junction to follow the Bryngwyn Line track into the hills (coming soon) or continue to the WHR station, and pub, at Waunfawr.

This route is suitable for walking, running or cycling. Some of the tracks are gravelly, and you may need a hybrid at least with two sections only walkable with a road bike.
The Route 1 – The route starts at the Caernarfon WHR Station, where at the far end of the platform you’ll see the start of the Lon Eifion cycletrack. There’s a bike pressed into wood – see the photo below – to indicate this.

2 – Follow this path for 10 minutes or so, when you’ll come to a crossing and a sign for Lon Gwyrfai. Cross the railway at this point and follow the path under the road and back up the other side.

3 – Follow the old road across Pont Saint, just be aware that it’s still in use by residents! Pass through the bollards and follow the track alongside the busy main road for a 100m or so.

4 – Follow the minor road that leads off left and uphill, still clearly signposted and follow this along the minor road, turn left at a junction and cross the main road after about 2km total. Follow the track opposite, and this leads you up eventually towards Plas Glan yr Afon, the final section being rough and gravelly.


5 – Pass through the farmyard, to the right through some gates and then onto the tarmacked section of new cycletrack. The views now start to open up.


6 – At the end of the cycle path, there’s a cross roads. Turn right and downhill towards a bridge over the Gwyrfai known locally as Pompren – a derivation of Pont Pren or the Wooden Bridge and only notable as the only wood near it is growing from the ground.


7 – The track continues muddily uphill, through a farm and within minutes to Tryfan Junction. This has recently been renovated, and there’s also a footpath into the hills from here (route to follow)

8 – Continue along the lane for a short distance, before turning right along a minor road into Bontnewydd. Turning right at this point takes you in 1.5km to the Waunfawr WHR Station.

9 At Bontnewydd, turn right along the main road (past the Newborough Arms, if you feel thirsty) and continue until you reach the crossing. This road is next to impossible to cross at peak hours otherwise! Once across, continue right past some council houses on a parallel residential road and then left at the end of the terrace.

10 This takes you along a minor road, and when you again reach the Afon Gwyrfai, the road passes under the railway bridge, you need to turn right up the cycle track that’s marked Caernarfon. This takes you to the Bontnewydd Station. Turning left takes you to Dinas Station, and right takes you in just under 3km into Caernarfon.
