Rhaeadr Idwal is the scenic waterfall formed as the outflow of Llyn Idwal tumbles toward the Ogwen Valley. Cascading over ancient volcanic rock, it is a highlight of the approach path from Ogwen Cottage. Nearby, the Devil’s Appendix plunges 93 meters down the cliffs of Twll Du, making it the tallest single-drop waterfall in Wales. These falls are most dramatic after heavy rain or when frozen into spectacular ice columns in winter.

The view you are most likely to see is from the top of the falls, to the side. There is a rock shelf that provides a good view for this view. In the summer you will also find people jumping off this shelf into the plunge pool below! There are other views that can be reached down a gully and then along a rough path that takes you to river level.

The Llantysilio Green weir, more commonly known as the Horseshoe Falls, is a 140-meter-long, horseshoe-shaped weir designed by Thomas Telford in 1808 to divert water from the River Dee into the Llangollen Canal. This prominent structure is a significant piece of engineering and a feature of the World Heritage Site, providing water for the canal and attracting tourists with its unique design and surrounding landscape. The Llantysilio Green Car Park is a designated access point for visiting the falls. In the late 19th century a long piece of wood, about 30cm wide, floated on the water here to deflect floating debris away from the canal intake. It was fixed at one end. It’s visible in the photo, taken c.1890. Some trippers couldn’t resist the temptation to walk along it, ignoring a warning sign nearby, if they weren’t spotted by the “waterman” in charge of the sluice. Local residents took a dim view of such “unheeding folly”. 😂😂

Here the water flows calmly, just before it thunders through the rocks! 😊

Several waterfalls in the Cambrian Mountains are suitable for families. Aber Falls offers well-maintained trails, making it accessible for all ages. Sgwd Yr Eira, while involving some steps, is a memorable experience where you can walk behind the water, and Sgwd Gwladus Waterfall is also a beautiful walking area with picnic spots. The Hafod Estate also features various walking routes, some less taxing, that lead to lovely waterfalls like Rhaeadr Peiran and Mossy Seat Falls.
Yes, some waterfalls offer easier access. Pistyll Rhaeadr, often called one of the Seven Wonders of Wales, has a car park and café on-site, making its dramatic base easily reachable. Cenarth Falls features an accessible boardwalk along the riverbank on the Ceredigion side. For Aber Falls, there are well-maintained trails, and free parking is available just below the stone bridge, with additional paid parking higher up.
The best time to visit the waterfalls is generally after periods of rain, which ensures they are in full flow and at their most spectacular. This often means spring and autumn, when the surrounding landscapes are also vibrant with new growth or autumnal colours. Autumn is particularly special at Cenarth Falls, as it's known for migratory salmon and sewin leaping upstream.
The waterfalls are set within diverse natural landscapes. At Devil's Bridge Falls, you'll find a deep, ancient wooded gorge, rich in mosses, lichens, and ancient Sessile Oak woodland. Cenarth Falls offers picturesque cascades and pools on the River Teifi. Hafod Estate showcases a blend of natural beauty and historical landscape design, with various walking routes. The area around Furnace Falls is part of the stunning Cwm Einion, and the nearby RSPB Ynys-hir Nature Reserve adds to the appeal.
Yes, the region is rich in history and folklore. Devil's Bridge Falls is famous for its three bridges built one on top of the other, with the oldest said to have been built by the Devil himself according to local legend. The Hafod Estate waterfalls are part of a landscape designed in the 18th century to create a 'picturesque' setting. Furnace Falls is located upstream from the historic Dyfi Furnace, which historically harnessed the river's power for industrial use.
Beyond enjoying the waterfalls themselves, the Cambrian Mountains offer a range of outdoor activities. You can find numerous waterfall hikes, including the popular Four Waterfalls Walk in the Brecon Beacons (which includes Sgwd Uchaf Clun-Gwyn Waterfall and Sgwd y Pannwr). The region also provides excellent opportunities for cycling and running trails, with routes like the Mawddach Trail and various loops around lakes such as Llyn Efyrnwy.
For a more tranquil experience, consider visiting Ffrwd Fawr Waterfall in the dramatic Dylife Gorge. This lesser-known but beautiful waterfall offers a wild and peaceful setting, perfect for those seeking an off-the-beaten-path destination away from larger crowds. The walk to good viewpoints is short, though it can be uneven.
Given the often wet and rocky conditions near waterfalls, it's advisable to wear sturdy, waterproof walking boots with good grip. Waterproof clothing, such as a jacket and trousers, is also highly recommended, especially if you plan to walk behind waterfalls like Sgwd Yr Eira or Sgwd Gwladus Waterfall, where you are likely to get wet.
Yes, some waterfalls have facilities nearby. Pistyll Rhaeadr has a café and car park on-site. Devil's Bridge Falls also offers free parking. In Pontneddfechan, a common starting point for the Four Waterfalls Walk, you can find pubs, a bistro, and a car park. For Aber Falls, toilets are available at the upper car park.
While specific designated wild swimming spots are not widely advertised for safety reasons, Sgwd Gwladus Waterfall is mentioned as a great place for picnics and is considered safe to swim in during the summer months. Always exercise caution, check water levels, and be aware of currents and submerged hazards if considering wild swimming.
Devil's Bridge Falls is world-famous for its unique geological formation and historical significance. It features a series of cascades plunging into a deep, ancient wooded gorge, with a total drop of 91 meters. Its most distinctive feature is the three bridges built one on top of the other, spanning the River Mynach, with the oldest bridge steeped in local legend. It's also a Site of Special Scientific Interest (SSSI) due to its rich flora.
Pistyll Rhaeadr is one of Wales' most impressive waterfalls, often referred to as one of the Seven Wonders of Wales. It falls in three stages over a 73-meter cliff face, and uniquely, part of the waterfall flows through a natural rock arch. Despite its dramatic height, the base of the waterfall is easily accessible, with a car park and café on-site, making it a popular and convenient natural wonder to visit.
