Llyn Geirionydd is a popular lakeside picnic spot.

You can follow our circular waymarked walking trail from Llyn Geirionydd through the forest to the nearby lake of Llyn Crafnant - enjoy views of the lakes and the mountains along the way.

Llyn Geirionydd was reputedly the home of the 6th century poet Taliesin and a stone monument to him stands by the lake’s north bank.

In the 1870s this was a derelict industrial landscape - in fact, the car park lies on a waste tip near an old lead mine entrance.

Walking trail

The walking trail is waymarked from start to finish.

Look out for the information panel at the start of the trail.

Geirionydd to Crafnant Trail

  • Grade: Moderate
  • Distance: 5 miles/8 kilometres
  • Total climb: 300 metres
  • Time: 2-3 hours
  • Trail information: The trail is on a combination of forest roads, tarmac road, and a steep narrow footpath, less than 80cm wide in some places, on an unmade and uneven surface, where you can expect mud, rocks and tree roots. There are two small fords to cross and a kissing gate just before you meet the council road. There are also two forest barriers you will need to walk around with a gap of around 70cm at the side. There are picnic benches and toilets in both car parks, and a bench at the viewpoint above Crafnant.

This trail goes through the forest and takes in the two beautiful lakes of Geirionydd and Crafnant.

Follow the trail past the southern end of Llyn Geirionydd until the path narrows and casts you into the shelter and dappled light of tall larch trees.

Descend steeply through a shady silent spruce plantation and then pass ash and hawthorn hanging heavy with moss and lichen, a sign of the clean air here.

Continue on tarmac and forest road alongside Llyn Crafnant, climbing to a viewpoint over the lake, then descend back to Llyn Geirionydd.


Other walking routes

There are three waymarked walking trails from our car park at Llyn Crafnant, one of which is an accessible trail.

One of the Trefriw Trails, a series of nine waymarked walking trails from the village of Trefriw, leads to Llyn Geirionydd.

Gwydir Forest Park

Gwydir Forest Park lies in the heart of the 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.

In addition to the walks from Llyn Geirionydd, waymarked walks and two red-grade mountain bike trails start from several other Natural Resources Wales car parks in Gwydir Forest Park.

Opening times

Please check the top of this page for any changes to these opening times.
