Arthog Waterfalls Walk

This walk visits the North Wales village of Arthog where you can enjoy a lovely walking trail along a series of waterfalls.
The village is located in the Meirionnydd area of Gwynedd, near Dolgellau.
Start the walk at the car park on the estuary, which is located right on the Mawddach Trail.
Walk Report October 7th 2026 By Gareth Williams:
The Arthog Waterfalls walk is short enough to fit into a morning, but there is more climbing involved than I expected from a route of less than two miles. I started from the car park beside the Mawddach Estuary, where the views across the water towards Barmouth made a good introduction.... After following the Mawddach Trail for a short distance, I turned inland towards Arthog village and the woodland above it. The weather was bright, although the ground beneath the trees was still damp in places.
The climb begins quite abruptly, with uneven stone underfoot and a few slippery patches where water runs across the path. It is worth taking this section slowly, particularly if it has rained recently. Once higher up, the path levels out a little and the woodland becomes the main attraction, with moss-covered rocks, ferns and thick greenery crowding around the stream. I came across a few sheep near the path, another reminder that this is working countryside as well as a popular walking spot.
One of the nicest places to pause is the old stone bridge over the stream. In the sunshine it felt like a natural picnic spot, with the sound of running water coming up through the trees and a view along the little valley. I stopped here for a while before continuing towards the waterfalls, and it was a welcome chance to catch my breath before exploring the steeper section.
The waterfalls are not all concentrated in one place; the stream tumbles down through the woodland in a succession of cascades. Some are small and delicate, while others drop over rocky ledges into pools below. I followed the path alongside the water, stopping at the best viewpoints and looking for the little falls that can be easy to miss from the main trail. The woodland setting gives the whole place a secluded feel, even though the estuary and Mawddach Trail are only a short distance away.
The descent needed just as much care as the climb. There are steep steps and uneven sections, with grip especially important on the damp stone surfaces. I was glad I had proper walking shoes rather than trainers, as several walkers recommend, and I wouldn't rush this part of the route. The falls are at their most impressive when there has been recent rain, but that is also when the paths can be most slippery.
Back down near the estuary, the change of scenery was striking. After the enclosed woodland and rushing stream, the open views across the Mawddach felt wonderfully spacious. The Mawddach Trail also offers an easy way to extend the outing if you have more time, with wide views across the water and the mountains beyond.
Arthog Waterfalls is a good little walk for anyone exploring this part of southern Eryri. The combination of the estuary, the short but steep woodland climb, the old stone bridge and the succession of cascades makes it feel much more varied than the distance suggests. Allow time to stop and explore the smaller waterfalls, and take particular care on the rocky paths if the weather has been wet.
Just to the east of the falls you can visit Cregennan Lakes on the northern slopes of Cadair Idris. There's a nice footpath round the lovely lakes with the the Cadair Idris Visitor Centre also located near by. The centre includes a wealth of information and an exhibition detailing the wildlife and geology of this fascinating area.
You can extend the walk by picking up the Mawddach Trail shared cycling and walking trail. The popular route runs along the old Ruabon to Barmouth railway line and can be picked up directly from the car park. There's fine views across the estuary to Barmouth on the opposite side. You can visit the town by picking up the Panorama Walk just to the west of the village.
The circular trail climbs above the town for excellent views back down to the estuary. The route also visits the Dinas Oleu hill fort.

Some of a large series of waterfalls as the stream tumbles about 200 metres down through the woodland to Arthog.

Waterfall in the Arthog Woods. This waterfall is one of the more picturesque ones in the woods and is seen to best effect from a slight detour from the path.

Green ferns and moss abound in this wood. The waterfalls are seen below the main path leading up through the woods.

Old Clapper Bridge above Arthog. The stream soon drops about 200 metres down to Arthog over a series of waterfalls in a distance of less than 1 km.

Originally intended to be part of a development to rival Llandudno, this terrace and Mawddach terrace, as far as I know, were all that was built.
