As one of Eryri’s (Snowdonia) most iconic waterfalls, Rhaeadr Ewynnol, or Swallow Falls, is also one of the more accessible in the region, making it suitable for families and visitors of all abilities.

Located just outside Betws-y-Coed, this spectacular cascade tumbles through a wooded gorge, offering breath-taking views from well-maintained paths and viewing platforms. Its proximity to the main road and easy-to-navigate trails means you can enjoy the beauty of the falls without a strenuous hike, making it an ideal stop for a relaxing day out.

The paths leading to the upper viewing areas are relatively smooth and short, allowing wheelchair users and families with pushchairs to experience the waterfall’s grandeur with minimal effort. However, be aware that disabled access is only between April and October and there are steps to the lower sections of the falls.

While exploring waterfalls in Wales, you’ll find yourself picking up some Welsh. When it comes to waterfalls, “rhaeadr” means waterfall, “afon” means river and “nant” means stream. However, there are some differences, as waterfalls in North Wales are often “rhaeadr” or “pistyll,” while in South Wales they’re usually called “sgwd”.

While Pistyll Rhaeadr is just outside the edge of Eryri (Snowdonia), it stands as the highest waterfall in Wales and is truly unmissable if you’re in North Wales or visiting the National Park.

Often described as one of the most dramatic and beautiful waterfalls in the UK, its single drop of around 73m (240 feet) plunges into a serene pool below, framed by rugged cliffs and fresh greenery. The sheer scale and elegance of the fall make it a breath-taking sight for photographers and nature lovers alike.

As one of the more accessible waterfalls in the region, an short walk leads to the base of Pistyll Rhaeadr, offering you the chance to experience its power up close. However, the path is rugged and includes some steps, making it less suitable for wheelchair users.

For walkers and outdoor enthusiasts, the surrounding area provides excellent trails through the Berwyn Mountains, combining the drama of the waterfall with sweeping views of valleys and hills.

The charming cascades are framed by mossy rocks and dense forest, creating a peaceful backdrop for walkers who love immersing themselves in nature. Its location at the end of the Talyllyn Railway line adds a unique touch, making it a perfect blend of adventure and heritage.

The series of cascades can be followed as you walk deeper into the valley, and for those who love exploring, this area is home to the ‘secret’ Bryn Eglwys Quarry Waterfall, hidden among the remnants of an old slate quarry. You can discover it by venturing along rugged paths and tracing the old tramlines that once served the quarry, which transport you back into Wales’ past.

With optional routes ranging from gentle riverside strolls to more challenging climbs through the hills nearby, Nant Gwernol provides endless possibilities for outdoor enthusiasts seeking variety, beauty, and a touch of mystery.

This area can get very busy in peak season and you’ll need to get there early to secure parking. Ensure you are in an official parking spot and not causing any blockages for local buses and businesses. The Sherpa Bus (S4) will also drop you at Pont Bethania if you can’t find parking.

As the ultimate spot for wild swimming in Eryri (Snowdonia), the Watkin Path waterfalls are a true gem for outdoor enthusiasts.

Nestled along the lower section of the Watkin Path, these falls tumble into a series of crystal-clear pools, creating natural plunge pools that are perfect for dip after a hike. Surrounded by the rugged mountain scenery of Yr Wyddfa (Snowdon), it’s one of the most beautiful places to combine walking with a refreshing swim.

The area offers plenty of opportunities for walkers, with the Watkin Path itself leading all the way to the summit of Yr Wyddfa (Snowdon) for those seeking a challenge. If you’d prefer something more gentle than a climb to the peak, the lower section of the path provides easy access to the pools and waterfalls, where you can relax and enjoy the sound of rushing water.

Be aware!

Please be aware that the Watkin Path pools can be dangerous after poor weather. Heavy rain creates dangerous undercurrents, which can pull you beneath the water. Always use caution when wild swimming.

Set away from the main tourist routes, this enchanting cascade flows through a secluded woodland setting, creating a tranquil atmosphere that feels worlds away from the crowds. Its dark, moss-covered rocks and tumbling water give it a mysterious beauty, making it a rewarding find for walkers who love discovering lesser-known spots.

The surrounding trails offer plenty of opportunities for exploration, with paths winding through ancient forests and opening up to scenic viewpoints along the way.
