Gwydir Forest Park - Penmachno, near Betws-y-coed

What's here

There is a diversion around the Fedw Deg section of the Dolen Eryri mountain bike trail. Please follow all instructions and diversion signs on site.


The Penmachno Trails are situated near the village of Penmachno within the spectacular landscape of Gwydir Forest Park.

These two very remote and natural feeling mountain bike trails have a mixture of singletrack descents and technical climbs.

Each trail is a circular loop and you can either follow just the first loop (Dolen Machno) or you can join the second loop (Dolen Eryri) at the halfway point of the first loop for a longer ride.

The Penmachno Trails are managed and maintained by Menter Bro Machno (a local volunteer community group).

Gwydir Forest Park

Penmachno is in Gwydir Forest Park.

Gwydir Forest Park lies in the heart of the Eryri (Snowdonia) National Park and encircles the village of Betws-y-coed.

Lead and zinc mining once dominated the area and the legacy of old engine-houses, waste tips and reservoirs are characteristic features of the forest landscape today.

Several of the most important mines have been partially restored and made safe for visitors.

Waymarked trails start from Betws-y-coed and several other Natural Resources Wales car parks in Gwydir Forest Park:

  • Betws-y-coed - peaceful forest walks away from the tourist bustle
  • Cae'n y Coed - easy-to-find picnic area and walk with panoramic mountain views
  • Cyffty Mine - short trail around abandoned lead mine
  • Dolwyddelan - walking trail along Roman road and cycle trail with mountain views
  • Hafna - walking trail through lead mine ruins and red-graded mountain bike trail
  • Llyn Crafnant - walking trails around the lake and accessible riverside trail
  • Llyn Geirionydd - picnic site with walking trail around two beautiful lakes
  • Llyn Sarnau - picnic spot with a walk to two scenic lakes
  • Sawbench - two red-graded mountain bike trails and historical walk
  • Ty’n Llwyn – walking trail to the famous Swallow Falls waterfall

National Forest for Wales

Gwydir Forest Park forms part of the National Forest for Wales.

The National Forest will:

  • create areas of new woodland
  • enhance existing woodlands
  • restore Wales’ irreplaceable ancient woodlands

It will form a connected ecological network running throughout Wales, bringing social, economic and environmental benefits.

Parts of the network will eventually form a trail running the length and breadth of Wales, so anyone can access it wherever they live.
