Located at the southern end of the Eryri (Snowdonia) National Park, Dolgoch Falls is a stunning series of three cascading waterfalls tucked into a lush wooded gorge. I’ve visited the falls many times with friends and relatives, and I’m always amazed by how easy they are to access, yet how wild and unspoilt they feel as soon as you enter the woodland. Suddenly, the tarmac and noise of the nearby road seem like a distant memory.
The three waterfalls are part of the Nant Dôl-goch stream, tumbling down in a series of dramatic drops where rushing water meets mossy rocks and dappled woodland light — something photographers will appreciate straight away. There are well-marked walking trails and a few picnic tables, which makes it a good spot for the whole family to enjoy.
But the secret to making the discovery of Dolgoch Falls even more special is to arrive not by road, but by rail — via one of the most iconic narrow-gauge steam trains in Wales. That is when you truly feel you’ve entered an enchanting world.
Things to See and Do at Dolgoch Falls
The main attraction, of course, is the walk up through the waterfalls. A network of footpaths and bridges allows you to follow the cascades as they tumble down the wooded ravine. The lower fall is the easiest to reach and the first you’ll see. There is a viewing area, accessible via a few steps, which is ideal for selfies and family photos. You may also be curious to investigate the cave to the left of the lower fall, but it actually just leads to a locked gate a few metres inside.
The falls are especially impressive after a night of heavy rain, when you can really hear the water roar through the gorge. Nature lovers will enjoy the woodland setting, which is home to ferns, mosses and wildflowers. Photographers will find plenty of spots to stop and capture the scenery — bring a tripod and some ND filters if you have them!
Reaching all three waterfalls does not take long — less than an hour at a relaxed pace — but be aware that there are uneven sections, steep steps and rocky parts. I’d say it’s suitable for families with older children who are comfortable on rough paths. And although rain can make the falls more dramatic, it also means you’ll be walking on wet, slippery rocks. As always, I recommend wearing appropriate footwear.
The area is dog-friendly too, though keeping pets on a lead is advisable due to the steep drops near the waterfalls.
If you want to make a day of it, combine your visit to Dolgoch with a ride on the Talyllyn Railway, the narrow-gauge steam train that inspired Rev. Awdry’s Thomas the Tank Engine books. It is one of the most beloved preserved railways in Wales, and you can start your journey in Tywyn (a one-way ride takes about half an hour). From Dolgoch station, it’s just a short walk to the falls, and you’ll also find picnic areas nearby.
During school holidays, the Dolgoch Tea Room / Bed And Breakfast near the car park opens, offering a selection of snacks and refreshments.
If you’re keen to explore more natural wonders nearby, Nant Gwernol at the end of the Talyllyn line is home to another stunning woodland, as well as history trails to discover (and even a secret waterfall). The family-run Railway Inn in the village of Abergynolwyn is also a worthy stop for a pint or an excellent meal.
quick facts about dolgoch falls
- ‘Dol goch’ means ‘red meadow’ in Welsh, and the name comes from the stream Nant Dolgoch
- The Dolgoch Slate Quarry was dug into the west wall of the gorge. Despite having the advantage of transport via the Talyllyn Railway — originally built to carry slate from the nearby Bryn Eglwys quarry down to the coast — it remained open for less than ten years (1877 to 1884).
- The nearby village of Abergynolwyn was built to house quarry workers, and the remains of Bryn Eglwys quarry can still be seen along the nearby Nant Gwernol woodland walk.
Best Time to Visit Dolgoch Falls
If I had to pick one season, it would be autumn, when the warm colours of the foliage make the whole woodland more photogenic and create a striking contrast with the fast-flowing water. It’s also an excellent time of year for photographers.
Any day of the year after rainfall is a good time to visit, as the cascades are louder and more powerful — although this also means muddy trails, so wearing good shoes or boots is recommended.
Dolgoch is a popular spot for families and visitors in summer, as well as during special events organised by the Talyllyn Railway. The woodland also provides a cool retreat when you’re looking for some shade on a hot, sunny day.
