Machynlleth and Llyn Glanmerin – a short walk

A short (~ 4miles with 750ft climb) circular route from Machynlleth to visit beautiful Llyn Glanmerin. This is a relatively easy walk for any regular walker, including children. It does have a climb near to the start, so some fitness is advised. Tamsin and I walked this at the beginning of June whilst our car was in the garage for maintenance. There’s plenty of views & wildlife to take in on this pleasant stroll.

For convenience I have started the walk from the main Pay & Display Car Park in Machynlleth (Loos available at CP entrance). Exit the back of the car park and turn left on to a pleasant tarmac walkway which will lead you past the library and on to the high street. Turn right & follow the pavement until you reach the road turning right for Forge & Dylife, take this turning. Close to the end of the housing you will see a signposted footpath leading to the right. Follow this footpath away from Machynlleth, uphill on the right edge of the local common land. As you climb above the golf course on to bracken & heath, do look back at the view of Machynlleth nestled amongst the hills of Dyfi.

Continue uphill across this now heathy common land. The track now strays from the righthand edge a little, crossing open land from one block of woodland edge to another. Keep an eye open for Red Kites gliding across the skies above you.

When you meet Glyndwr’s Way crossing you from wooded left to open heath right, keep straight ahead into a narrow wooded path that takes you on a brief detour to Llyn Glanmerin. As you emerge from the forestry Llyn Glanmerin is immediately down to your left. Llyn Glanmerin is sometimes referred to as Lord Herbert’s lake. Lord Herbert Vane Tempest of Plas Machynlleth was a director of the Cambrian Railways. He sadly died, along with 16 others, in the Abermule train crash of 1921. The lake itself is of about 7 acres in area and is most picturesque with water lilies floating upon it and Rhododendrons on its banks.

On a warm summer day Dragonflies & Damselflies are to be seen patrolling the water’s margins in search of a mate or laying eggs beneath the surface.

Skimmer Dragonfly
I believe this to be a female Black-tailed Skimmer (Orthetrum cancellatum) Dragonfly; with dark pterostigma yet golden costa.

Now briefly retrace your steps through the narrow section of woodland, back to Glyndwr’s way. Upon meeting the Glyndwr’s way path, turn west along it and over the open heath land. This well marked path will then lead you downhill towards the Cae-Gybi lane. As you descend, see if you can spot Plas Machynlleth (Lord Herbert’s old home) beneath you at the edge of Machynlleth.

Upon meeting the lane, turn right along it briefly, before again leaving it to follow Glyndwr’s way down to Plas Machynlleth. Turn right & walk along the path through Plas Machynlleth’s grounds. This will lead you to the back of the car park from whence you began the walk.

Return to Rhiwargor

Or more accurately, another trip to Pistyll Rhyd-y-meinciau.

This is a walk that inspired the digital painting that I’ve used as a featured header above; if you like it, the print is for sale on my Nature’s Universe Store.

The walk is a relatively unchallenging one (about 1.5 miles 300ft climb), assuming that you choose not to scramble up the side of the falls. The character of the falls can change dramatically from a soft refreshing cascade on a hot sunny afternoon to a roaring torrent as the winter snows melt. The river falls about 275 feet in the several stages shown by the slideshow pictures below:

Note: some of these photographs are taken from vantage points gained by climbing the falls.

At the head of Vyrnwy lake there is a good car park (see map for details), signposted Rhiwargor. The car park has beautiful views & an interesting ironwork sculpture. A great place for a picnic but please note that the nearest public loos are some miles away, back near the dam.

Follow the path out of the far end of the car park, dropping slightly downhill towards the river & through the footpath gate. Upon reaching the river turn upstream and follow the riverbank path in a westerly direction. When you reach a point where there is a vehicular bridge over the river, do not cross, instead stay straight ahead through the footpath gate. Continue to follow the path, twisting up & down hill along the left-hand riverbank. All the while you should be able to enjoy ever improving views of the waterfalls.
Upon reaching a wooden footbridge, cross the river and continue upstream for a short distance, to reach the base of the falls & a conveniently sited picnic table.

It is possible to clamber up the side of the falls but this is a more substantial & oft muddy task that is beyond the scope of this brief guide. So having enjoyed some time at the waterfall, now take the stoned forestry track back along the northern side of the river. Follow this until you are close to the vehicular river bridge, cross back over the river and retrace your footsteps back to the car park.
