Mawddach Way


48 km / 30 miles
The Mawddach Estuary is a beautiful and largely unspoilt gem hidden away at the southern end of the Snowdonia National Park. The Mawddach Way is a 50km walk which uses existing footpaths and permissive paths to makes a circuit of the hills either side of the estuary, passing through woodland, pasture and open country.

Although the tranquil setting and spectacular views may seem to be in keeping with the scattered remains of prehistoric settlement, they belie an altogether noisier and dirtier history of industrial exploitation and military use, and each remnant of the past provides plenty of interest to keep the walker entertained along the way.

There are details online on the website below, with links to purchase a printed or e-book route guide.

UPDATE October 2020 - Work to start upgrading the 150 year old Barmouth Viaduct starts in September 2020. It will affect the route of the path as it goes over the viaduct across the Mawddawch Estuary. During this upgrade the bridge will be closed temporarily on certain dates.
An alternative route is being looked into for walkers on the path and will be posted on this page. If you are planning to walk in this area, we suggest you also follow Network Rail social media for updates.
