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.

📖 Rhaeadr y Chwarel is A picturesque mountain waterfall tucked into the lower section of Cwm Llan, near the old slate quarry workings on the southern flanks of Snowdon. The name literally means “Quarry Waterfall,” a nod to the mining history of the area, you can still see traces of old quarry buildings, walls, and inclines nearby. 👥 Feels remote and peaceful. Take in the surroundings before tackling the steeper, rockier terrain above and the crowds at the summit of Snowdon. 🚗 From Rhy-Ddu car park, c. 2.8 miles. ☕ A perfect spot to stop for a brew as it is sheltered. ⚠️ Access is along the well-trodden quarry approach path, so you don’t need scrambling skills. (Unless you walk further up the path to the top of Snowdon) To sum up: Rhaeadr y Chwarel is one of those small but memorable landmarks on Snowdon’s southern approaches. It’s not a massive waterfall, but its mix of natural beauty and industrial heritage makes it stand out. A perfect spot to pause before the serious climbing begins.

Straight ahead over the bridge is the path to Cwm Idwal, but take time to see the waterfall and rapids on the River Idwal. Very pretty.

If you will turn right before bridge - you’ll go to the canyon with stunning small pond in the end. If you go straight on the bridge - you’ll follow path to the lake.
