Coed y Brenin Forest Park - Tyddyn Gwladys, near Dolgellau

What's here


Tyddyn Gwladys is the starting point for a walking trail to the famous waterfalls known as Rhaeadr Mawddach and Pistyll Gain. 

This circular trail also goes past the Gwynfynydd goldmine which closed in 1999.

In the car park, there are picnic tables under large trees beside the rolling Mawddach river.

Walking trail

The walking trail is waymarked and starts from the car park.

Waterfalls and Goldmines Trail

  • Highlights: The waterfalls alone make this walk worthwhile.
  • Distance: 2¼ miles, 3.6 kilometres
  • Grade: moderate
  • Trail description: Follow the forest road north along the river Mawddach in a steep-sided valley surrounded by big trees, towards the waterfalls. Follow the waymarkers along the east side of the river and cross the timber bridge back to the car park.

The trail is nearly all on forest road with one section of very rough private track before you get to the waterfalls and one steep but short climb 20%/1 in 5 after leaving them.

There are no steps or stiles and the trail is suitable for pushchairs and mobility scooters.

On this trail there are two benches, one picnic table and two gates with passing places 80cm wide.

Please stay on the waymarked trails as the old mine workings and buildings may be unsafe and there are unprotected drops into the river gorges.

You can also download an audio trail and listen to the history of the Tyddyn Gwladys Gunpowder Works.

There are numbered posts on the walking trail which tell you when to play each section.
