One of Eryri National Park’s most flexible and accessible trails

Stretching between Dolgellau and Barmouth, the Mawddach Trail is considered one of the most flexible and accessible trails in the National Park.

The 9-mile trail follows the southern shore of the Mawddach estuary—one of the National Park’s most abundant areas in terms of wildlife and history.

Why this path?

As an accessible trail, the Mawddach is suitable for people of all abilities. The trail’s wide and even surface makes it a perfect choice for wheelchair or off-road mobility scooter users.

It’s possible to join the trail from several locations, making the Mawddach an incredibly flexible option for those who’d like a shorter, more gentle stroll along the estuary.

Cycling is a popular activity on the Mawddach trail and can be a fantastic option for families looking for an adventurous day out.

The Mawddach estuary

The vast and sandy Mawddach estuary is one of the National Park’s most remarkable areas.

The area is designated a Site of Special Scientific Interest and a Special Area of Conservation due to its salt marsh and lowland peat habitats.

Nearby Arthog bog is home to an RSPB nature reserve full of incredible wildlife such as rare flowers, grass snakes, butterflies and all manner of birds.

The area was also the centre point to some of Eryri’s rich industrial past. On the estuary’s northern shore, the historic Clogau gold mine sits high above the village of Bontddu. Mining for gold was a popular activity in this area. Gold panning also took place in the Mawddach river itself.

During the 18th and 19th centuries, the Mawddach was home to a busy shipbuilding industry. A total of 318 vessels were built along the Mawddach between 1750 and 1865.

Mawddach Railways

The Mawddach trail follows the trackbed of the old railway line from Barmouth to Ruabon. The line was opened in 1865 and proved very popular with visitors. It was also used briefly to carry slate. The railway closed in 1965 as cars became a more popular way to travel.

Down towards the end of the estuary stands Barmouth Bridge, crossing between the northern and southern shores of the Mawddach. The bridge is a Grade II* listed single-track wooden railway viaduct stretching 820 meters between Morfa Mawddach and Barmouth stations. It is the longest timber viaduct in Wales and is synonymous with views of the estuary.
