Overview
Mahon Falls drops 80 metres over sandstone cliffs on the southern slopes of the Comeragh Mountains, forming a graceful cascade of the River Mahon. The waterfall is set near the village of Lemybrien, about a 25‑minute drive from Dungarvan and 40 minutes from Waterford City. Though the falls are tucked away in a relatively remote part of County Waterford, they are easily reached via a well‑signposted car park off the N25, at the top of the famous “Magic Road” where cars appear to roll uphill.
The site is a favourite for families, casual walkers and photographers alike. After a heavy rain the water thunders down the sandstone face, creating a dramatic spray; in drier periods the falls become a gentle, shimmering veil that can be approached from several angles.
History & Landscape
The Mahon Falls area has long been part of the natural heritage of the Comeragh range, a landscape shaped by glaciation and river erosion. The River Mahon, which feeds the falls, has carved a narrow gorge through the sandstone, exposing sheer rock faces that frame the water’s descent. While there is no recorded historic structure at the falls themselves, the surrounding mountains have supported centuries of farming, peat cutting and, more recently, tourism.
The “Magic Road” that runs beside the car park is a modern curiosity: an optical illusion created by the road’s camber and surrounding hills, making it appear that cars roll uphill when they are actually being pulled by gravity. The road has become a quirky photo‑op spot for visitors to Mahon Falls.
What to See & Do
The Easy Mahon Falls Walk
The most popular route is a short, looped trail that starts directly from the Mahon Falls car park. The path is a gently twisting gravel track that follows the ridge for about 1.5 km before reaching the base of the waterfall. From the car park to the falls takes roughly 20 minutes, and the return leg is of similar length, making the whole circuit just under an hour.
The walk is classified as easy to moderate – the surface is firm underfoot, but the terrain becomes rockier and steeper as you approach the cascade. The route is well‑marked, and the waterfall is visible from the start, so you always know where you are heading. Once at the base, you can stand on a natural viewing platform of flat rock and watch the water plunge into the river below. The surrounding heather and grass add seasonal colour, especially in late summer.
The Longer Mahon Falls Hike
For those seeking a more challenging experience, the Mahon Falls Hike (also known as the Mahon Falls & Coum Tay walk) is an 11 km loop that takes about four hours. The trail climbs over Coumfea Mountain, reaches a peak of 713 m, and then descends back to the falls. It is unmarked and requires solid navigation skills, a map or GPS, and a willingness to tackle boggy ground after rain. The route includes several sheer drops, so caution is advised.

Wildlife & Photography
The area around Mahon Falls supports a variety of birdlife, including meadow pipits and occasional raptors soaring over the ridge. The waterfall itself provides excellent opportunities for long‑exposure photography, especially after rain when the water is at its fullest.
Practical Information
Mahon Falls is a natural attraction with free entry. The car park is free and has a modest number of spaces, which can fill up during peak summer weekends. The site is not wheelchair accessible due to the uneven gravel path and rocky sections near the falls.
| Segment | Approx. Time | Approx. Distance |
|---|---|---|
| Car park to falls | 20 min walk | ~1.5 km |
| Return to car park | 20 min walk | ~1.5 km |
| Full loop | < 1 hour | ~3 km |
The short walk can be completed in any weather, though the longer hike should be avoided after heavy rain because the ground becomes very boggy and navigation can be difficult. The trail is not marked on the longer route, so a detailed map or a GPS app such as the ActiveME app is recommended for those attempting it.
To reach the car park, follow the N25 eastward from Dungarvan and look for signs pointing to “Mahon Falls”. The car park sits at the top of the Magic Road; entering “Mahon Falls Car Park” into Google Maps will guide you directly.
