Port Penrhyn to Tregarth
You will find the start of the Lon Las Ogwen at Port Penryn just outside Bangor. Take the turning to the port just before the sharp bend on the A5 (OS Grid Ref: SH 592 726).
Take the left fork, dropping down to find parking behind the white Old Port Office that sits at the start of the Lon Las Ogwen. Parking is safe here, but do ensure you remove valuables from your vehicle.
Heading south away from the Port, pass through the archway on to the trail in to woodland alongside a meadow. You will immediately spot the high boundary walls of the grand Penrhyn Estate & along the trail edge, slate fencing, a feature of the valley that you will see lots more of as you push up the valley.
Keep an eye open for the “Slate Trail” signage, it tells the history of the development of the Lon Las Ogwen and the people involved in the Bethesda slate industry.
After crossing the viaduct, pass under the A5 road bridge and enter the delightfully cool air of the Cegin Valley. The wood echoes with bird song & in the spring it is carpeted with bluebells & wood anemones.
Thanks to the hard work of local groups, this section of the river is now pretty well clear of the rubbish that used to litter the river banks. Otters have now re-established in the valley.
Kids, on one of the many foot bridges crossing the river, look out for the animal shapes on the bridge sides. See if you can find all four!
Pass under the grand red sandstone arches of the Cegin Viaduct which carries the coastal main railway line into Bangor.
Following alongside the river Cegin. Once clear of the industrial estate, the fields open up & you will catch you first glances of the long slopes of the Carneddi mountain range.
Need a quick drink stop? Look out on the right, across the bridge for the large fish sculpture/bench.
As the river drops away to the right, if it is not too wet, you can ride “off Trail” & follow some the minor diversions, good skills practise for the kids. But watch out - it can be a bit muddy!
Push on as the Trail gently climbs as you head towards the small village of Glasinfryn. The kids might complain on this bit of the Trail, as although only gently climbing, the long straight sections disappear away in to the distance with no break.
The tranquillity is quickly broken as you pass under the A55 Expressway on to a very short section of road through the underpass.
Re-join the Lon Las Ogwen & before you realise it, you’ll be at the bridge that crosses over the very busy A4244. Although the bridge is big, bright & colourful, it does make this ride safe if riding with the kids, avoiding this “nasty" road crossing.
Note that on the roadside, just below the bridge, limited parking a is available should you want to join the Lon Las Ogwen at this point.
The next delightfully leafy section with a small stream on the left take you up to the village of Tregarth.
Just before you arrive at the village, you can make a stop at Moel y Ci Farm – a community owned centre for the practice and teaching of sustainable farming. They have a lovely farm shop & café. You can access Moel y Ci Farm from the Lon Las Ogwen via a gate. You will see a public footpath sign, showing access from the Trail.
The Lon Las Ogwen eventually emerges at the road side in the village of Tregarth (OS Grid Ref: SH 600 679).
