Gwynedd Recreational Routes

Looking for a safe, traffic-free location for a spot of walking or cycling? Want to get away from the hustle and bustle of everyday life? Why not pay a visit to your local Lonydd Glas (Recreational Routes) network? Designed especially for walking and cycling, there are over 50.5 kilometres (31.5 miles) of these purpose-built paths in Gwynedd, where you can relax amid nature and forget about the outside world. Established along disused railway lines, these are quiet rural paths that lazily meander into the picturesque Gwynedd countryside; a region that is unique as regards to its landscape, its culture and people, and is also a stronghold for the Welsh language. This network is based on paths that are used by permission of Gwynedd Council and the Snowdonia National Peak Authority. The Lonydd Glas are there for your enjoyment, therefore your respect and good behaviour is sought at all times.

Lôn Las Ogwen

To walk this path south from Porth Penrhyn is like walking hand in hand with the River Cegin. This part of the route which runs between Porth Penrhyn and the village of Glasinfryn, was developed in the 1980’s and is also known as Lôn Bach. The disused narrow gauge railway upon which the path was built, was constructed by the Penrhyn Estate to transport slate from the quarries at Bethesda for export at Porth Penrhyn. By today, Lôn Bach is part of Lôn Las Ogwen which continues south on its journey, stretching lazily over the viaduct at Glasinfryn to Tregarth, and past Penrhyn Quarry into the Ffrancon Valley.

 
Lôn Las Ogwen is an on-going project, which aims to complete the Bangor to Bethesda link. For a map of the journey you can download: Lôn Las Ogwen Recreational Route (PDF, 1.36MB)

Lôn Las Menai

Lôn Las Menai is a 6.5km (4.5mile) path which runs between the historic town of Caernarfon and the village of Y Felinheli. From Caernarfon, the tarmaced path follows the former railway alongside the Menai Straits, enjoy the views across to the Isle of Anglesey. Before entering Y Felinheli, you will pass near to the National Water Sports Centre at Plas Menai. At Y Felinheli, for a short distance the route follows the main road into the village before continuing off road past the former station building.

Lôn Las Peris

From the popular village of Llanberis, Lôn Las Peris meanders lazily along the sheltered shore of Llyn Padarn. Shortly after the tunnel, the path connects onto the public road network from where you can walk or cycle through the villages of Cwm y Glo and Llanrug, and follow the Seiont River valley towards the busy town of Caernarfon. Alternatively, why not further explore the historic countryside of this slate valley known as the gateway to Snowdonia, by following country lanes to Deiniolen or Penisarwaun, or by cycling up the valley towards Nant Peris?

Lôn Eifion

Some people might say that Lôn Eifion is the most well known and well used cycle route on the network. Certainly it is worth a visit, if only to feast your eyes on the breathtaking views. Indulge yourself in the blues and greens of the Llŷn Peninsula to the south west, Caernarfon Bay and Anglesey to the west and north, and the impressive mountains of Snowdonia to the east. Lôn Eifion is a green avenue of native trees and plants which stretches between the busy historical town of Caernarfon and the rural village of Bryncir to the south.

Trawsfynydd Route

The path follows the eastern shore of Trawsfynydd Lake through woodlands and open country. Much of the path was built on land owned by the Trawsfynydd Nuclear Power Station, which is currently being decommissioned. Be aware that in the vicinity of the power station and its visitor centre, the route crosses roads used by vehicles. A cycle path provides a link along the A470 to Trawsfynydd village. For a map of the journey you can download Llwybr Trawsfynydd Route (PDF, 1.37MB)

Mawddach Trail

Winding lazily along a disused railway track, the Mawddach Trail which is owned and managed by the Snowdonia National Park Authority, follows the Mawddach estuary from Barmouth to Dolgellau. The path, having been surfaced using compacted dust, has further been developed between Penmaenpool and Dolgellau to cater for disabled users. Awe inspiring views can be seen whilst walking and cycling the path, especially of the estuary and the spectacular Barmouth bridge. Also, hidden along the path verges and outlying land are species rich habitats such as wetland and forestry, for example Coedydd Abergwynant, a woodland adjacent to the path which is owned by the Authority.

Health Benefits

Regular and moderate cycling or walking can:

  • Lower blood pressure.
  • Lower cholesterol levels.
  • Strengthen bones and muscles.
  • Help to control your weight.
All the above contribute to a wide range of health problems, including coronary heart disease. Walking and cycling can reduce the risk of a stroke, diabetes, osteoporosis and obesity. If you're out of practice for walking or cycling, the mainly flat and traffic free Lonydd Glas routes can offer you an excellent place to get back into the habit.

Y Cob

Over the centuries many had dreamed of providing a safe way to cross over the treacherous sands of Traeth Mawr, but it was William Alexander Maddocks of Denbighshire who eventually realised this dream. Construction work on the Cob embankment began in 1807, and was eventually completed in 1811 at a cost of £160,000.

The Cob project also reclaimed acres of agricultural land from the wetlands and marshes, and it was on this land that Maddocks built Tremadog, and on which most of the town of Porthmadog was also built.

 

330 270 Y Cob

In 1830 the Ffestiniog Railway was established along the Cob to transport slate from the quarries at Blaenau Ffestiniog for export at Porthmadog. 

In 2001 the Cob was strengthened, the roadway widened and a new embankment built to carry a pathway for walkers and cyclists on the landward side. Apart from being an excellent viewing area for observing the wide variety of wildlife that can be found on the Glaslyn salt marshes, the path is also part of the Lonydd Glas Gwynedd network, and the National Cycle Network.

Management & Conservation

Whilst managing the Lonydd Glas network, Gwynedd Council and the Snowdonia National Park Authority keep two main aims in mind – to enhance your enjoyment of the routes, and to protect the wildlife which can be seen on either side of the paths. We try and meet the first aim by maintaining the path surfaces, and providing bicycle racks, picnic tables and information panels at the more popular sites.

 

330 270 Moch Daear - Badgers

Countless numbers of different plant, bird and animal species have settled along the routes, with many of these being quite rare or are protected by law, such as the elusive badger. The paths act as natural corridors along which wildlife can travel under cover through the countryside. The many different habitats that we manage along the path verges such as woodland, wet pastures and scrub land, all contribute towards making the Lonydd Glas network a world of its own. 

We appreciate any help or co-operation from you towards managing the Lonydd Glas.
