Total steps: 9

Total steps: 9

Start point

Ganllwyd car park, grid ref: SH727243

Step 1

Cross the road from the car park towards the recently-restored corrugated iron village hall.

Step 2

Follow the tarmac road alongside the River Gamlan to its junction with a stoned footpath, waymarked towards a wooden bridge. As you follow this path look out for a rock inscribed in Latin with a line by the poet Thomas Grey.

Step 3

Cross over the bridge and veer right to Rhaeadr Ddu: the Black Falls. There are two separate waterfalls, both spectacular in all seasons.

Step 4

Continue along the path, following the waymarkers through a kissing gate. A little further on, take the path to your right and cross the wooden footbridge. Carry on along the path to your right, up a tarmac road and through a gate into into recently clear-felled NRW forestry.

Step 5

After about 110yds (100m) turn left up the forestry track. Follow the waymarkers over a rustic oak footbridge and onto the open mountain. From here the waymarkers will take you past the 19th-century gold workings. The path will lead you down to the ruined cottage of Berthlwyd.

Step 6

Walk downhill along the tarmac road as far as the stone house on the left. Take the path to the right and through the gate and into the woods.

Step 7

Carry on along this path until you reach a junction. Take the second path to the right and follow the waymarkers through the woods. This path will bring you to the Merionnydd National Trust work base.

Step 8

Continue on along the tarmac road to the Tyn-y-Groes Hotel. Cross the busy main road and take the path opposite, towards the River Mawddach and the Tyn-y-Groes bridge.

Step 9

Go left along the tarmac road back to the main road. Cross over to the pavement and turn right, back towards the village and the car park.

End point
