A circular walk of 9 miles including 1,400 feet of elevation overall. Start Point: Opposite Trefriw Woollen Mill, Main Road, Trefriw LL27 0NQ.
Llyn Crafnant and Llyn Geirionydd are two of the largest natural lakes in the Conwy Valley (both around a mile long) and together, they make for a scenic, varied walk along mostly well-defined paths as part of the Trefriw Trails network. It’s possible to shorten this particular route and reduce the elevation by skipping the climb up from Trefriw and parking instead at either of the designated lakeside car parks.
Spring and autumn are especially rewarding seasons to enjoy this route due to the colour diversity of the trees, the bluebells and the wild garlic. And the falls by Trefriw Mill are especially spectacular when in full spate. Crafnant takes its name from ‘craf’, an old Welsh word for garlic, and ‘nant’, a stream or valley. The lakes run parallel to each other but a mile apart, being separated by Mynydd Deulyn, known as the mountain of the two lakes. Like much of Wales, the Crafnant valley has a long association with mining, and the Pandora Mine and Klondyke Mill (1900-1911) was for a short time an industrial lead ore enterprise. There are few, if any, fish in Geirionydd; quite likely the result of poisoning from the adjacent metal mines. However, the lake boasts a number of literary connections: Ieuan Glan Geirionydd (1795–1855) was born on the banks of Afon Geirionydd, and renowned for his poetry and hymns. Taliesin (c. 534–c.599), was a 6th-century Welsh bard, and the earliest poet of the Welsh language whose work has survived. Taliesin lived on the shores of Llyn Geirionydd, and this is also where many say he is buried.
- From the parking area, turn right along the main road then cross opposite The Fairy Falls Hotel and enter the side street, where a Trefriw Trails sign directs you along a footpath to the left. After a short distance, take the right turn indicated by another trails arrow alongside the river and follow the path as it hairpins back on itself, before crossing the bridge.
- Turn right after the bridge along a short path and then at the end, turn right onto a road. At the T junction, turn left, then look for the footpath sign into the woods. Follow the path for more than a mile as it climbs steadily towards Llyn Geirionydd, the way marked by yellow trail markers. At the rocky knoll there’s a good view of the remains of Klondyke Mill.
- The route continues over a stream, then up to a wooden gate. Continue on the trail until you reach the final stile which brings you to the outskirts of Llyn Geirionydd. Either walk along the single-track road to the left of the lake or take a right turn at the head of the lake and take the footpath along the far shoreline, close to the water’s edge.
- If you choose to walk along the road, take the first right after the end of the lake, then follow the footpath posts denoted by a footprint as they head up into the forest. If you’ve chosen to walk along the shoreline, then both routes conjoin here. Follow the forest track as it winds up and bears right.
- Once over the stream, cease following the markers and take a right turn up through the trees to arrive on the forest road again, then pick up the blue markers. Bear left and head towards the next marker nestled in the grass verge. Follow the directions up into the forest and walk along the track which climbs up through the fir trees, then descends towards Llyn Crafnant.
- Before the final stile on the track, turn left as indicated by several trail markers and follow the well-defined path within sight of the lake. Pass through the kissing-gate at the end then turn left at the single-track road. At the end, pass through the gate and turn right.
- Follow the stone path as it passes through another gate and then turn right to cross over a wooden bridge just before a dwelling. Continue along the stone path as it follows the natural shoreline of the lake. At the head of the lake, turn left onto the single-track road with the stream to your left. At the car park entrance, also on the left, look for a right fork denoted by a footpath sign and follow this wide path as it climbs up towards a gate.
- Pass through the metal gate and stay on the forestry road but ignore the sharp right-hand turn and go straight on, following the yellow markers to take a stile into a wooded area with slate heaps either side. The path here undulates through a wooded area and some of the way is hampered by tree roots and boulders. At the fork, take either path as they both conjoin later on at a ladder stile over the wall by a stream.
- Once over the wall, the path is distinct again as it heads back up towards Llyn Geirionydd and passes the monument dedicated to Taliesin on a rise to the left. Once back at the lakeside turn left and pick up the trail from point 3 to retrace your steps back to Trefriw.
