Clogau Trail and the Gold Mine

Overview

About Clogau Trail

A circular promoted walk of 6.5 km (4 miles), usually taking about 3 hours, graded Moderate. It starts and finishes at the lay-by at the Dolgellau end of Bontddu, just off the A496. Detailed mapping of the line, including its bends and the short access back to the lay-by, reads a little over 7 km, so allow for that if you track your walks.

Why go

  • Industrial heritage at Clogau gold mine
  • Mawddach estuary and mountain views

Heads up

  • Steep and unsurfaced sections with marshy ground
  • Road crossings and grazing fields need attention

Plan your hike

Before you go

Parking

Start at the lay-by at the Dolgellau end of Bontddu off the A496. Park only in designated areas and do not block field or residential entrances. The T3 bus between Barmouth and Wrexham stops at Bontddu.

Safety

Cross the A496 carefully. The gorge near Figra Bridge is steep and the river flow is strong. Expect steep or unsurfaced ground, marshy sections and livestock. Keep dogs on a lead in the permissive Garth Gell section and wherever animals graze.

“Bontddu is coming up, where the Clogau Trail climbs toward old gold-mine workings above the Mawddach. Gold from this mine went into Queen Elizabeth the Second's wedding ring.”

  • Cross the A496 carefully from the lay-by and take the public footpath down toward the Afon Mawddach, following the tidal bank and crossing a ditch bridge into Bontddu.
  • Climb on steep tarmac, then through oak woodland to Figra Bridge and the remains of an old mineral treatment plant.
  • Continue across fields and an old incline to the Clogau gold mine and its rubble heaps, once a significant local mine.
  • Cross mountainous grazing ground to Garth Gell, through a permissive section and Coed Garth Gell Nature Reserve, then descend through woodland to the start.

The loop pairs industrial heritage with quiet woodland and calm streams, grassy meadows and the wide Mawddach estuary. Higher ground opens views toward Cader Idris, Aran Fawddwy, Aran Benllyn and Rhobell Fawr. The estuary and the long mountain skyline are the strongest photographic subjects, and both sit best on the climbing and open sections rather than at the start.

Footing and difficultyBest suited to walkers with some experience and reasonable fitness.

Best suited to walkers with some experience and reasonable fitness. Expect steep or unsurfaced paths, marshy ground, gates and field paths, plus a stretch of steep tarmac out of Bontddu. Walking boots and waterproof layers are sensible.

The gorge near Figra Bridge is steep and the river flow there is strong, so keep well back from edges and water. Take care crossing the A496 at the beginning and end.
