Mawddach Trail, Recreational railway trail in Snowdonia National Park, Wales
The Mawddach Trail is a recreational path on a former railway line that stretches about 9.5 miles along the southern side of the Mawddach estuary. The flat, three-meter-wide route connects the town of Dolgellau to the coastal town of Barmouth while passing through varied terrain with river sections, hills, and moorland.
The path follows the route of the Great Western Railway, which connected the region from 1865 until closure in 1965 during the country's railway reduction period. Converting this former line into a recreational route preserved its role as a connection between communities.
The trail features bilingual signage and passes by historical structures like the wooden toll bridge at Penmaenpool from 1879. Visitors encounter these marks of local heritage naturally as they move through the landscape and connect with Welsh identity.
The flat path is easily accessible for walkers, cyclists, and wheelchair users with multiple entry and exit points along the route. Connections to public transport in Dolgellau and Barmouth make it simple to plan the start and end of your journey.
Two RSPB nature reserves border the estuary edge along the trail. These protected areas give visitors chances to watch water birds and wildlife from marked observation points.
