An 8km stretch of the old railway has been converted into a traffic free walking and cycling way. The views of Muckish Mountain are fantastic and there are old stone railway bridges along the way. Listen very carefully as you walk near Fiddler's Bridge as there is a waterfall nearby.

For a family-friendly outing, Glenevin Waterfall is an excellent choice. It features a well-signposted, walker-friendly route, and the 1km walk to the falls is relatively easy. There are also picnic areas nearby, making it ideal for a leisurely day out.
Yes, Assaranca Waterfall is one of the most easily accessible. It's located directly on the side of the road near Ardara, with a small car park at its base, allowing visitors to pull over and enjoy the view without a long walk. It's particularly impressive after heavy rainfall.
Donegal's waterfalls are often at their most spectacular after periods of heavy rainfall, which can occur throughout the year. This makes the water flow much stronger and more dramatic. While spring and summer offer milder weather for exploring, autumn can also be picturesque with changing foliage, especially around spots like the Lennon River Waterfall.
Yes, Largy Waterfall, often called the 'Secret Waterfall,' is a hidden gem located beneath the Slieve League cliffs. It cascades into a roofless sea cave and is only accessible during low tide, requiring a cautious walk over rocky terrain. Another lesser-known spot is the Sliabh Liag Waterfall, found along the cliff-side trails, where its sound blends with the Atlantic waves.
Many waterfalls are situated within areas perfect for outdoor activities. For instance, you can find various cycling routes in Donegal, including the 'Inishowen 100 Scenic Loop' or the 'Rossguill Atlantic Drive,' which might pass near some waterfall locations. For hiking, there are easy trails like those in Glenveagh National Park, which also harbors smaller cascades. You can find more details on routes in the Cycling in Donegal or Easy hikes in Donegal guides.
While many waterfalls are easily accessible, reaching Largy Waterfall (the 'Secret Waterfall') involves a challenging walk over rocky terrain, and careful timing with the tides. The reward is a unique experience within a sea cave. For a more remote feel, exploring the smaller, hidden cascades within Glenveagh National Park might involve navigating mossy forests and rocky ravines.
Yes, Glenevin Waterfall is known for having lovely picnic areas nearby, making it a perfect spot for a relaxing meal amidst nature. The Lennon River Waterfall, just outside Ramelton, is also described as an ideal spot for a picnic and a walk.
Astellen Waterfall is notably impressive, standing at a lofty 215m high, and is considered a true hidden gem, especially after heavy rains. Glenevin Waterfall also cascades down from around 40 meters, creating a beautiful sight.
Given Donegal's often wet and rugged landscape, it's advisable to wear waterproof and comfortable clothing, including sturdy, waterproof hiking boots with good grip. The paths can be slippery, especially after rain, and weather conditions can change quickly. Layers are also recommended to adapt to varying temperatures.
While not directly adjacent to major historical sites, the area around Assaranca Waterfall is on the way to the Maghera Caves and Beach, which offers natural geological interest. The Burtonport Railway Walk, which features a nearby waterfall at Fiddler's Bridge, also has historical significance as an old railway line, with views of Muckish Mountain and old stone railway bridges.
Glenevin Waterfall is at the end of a pleasant 1km walk through the Glenevin Valley. The Crolly Waterfall is also accessible via a scenic trail that winds through ferns and crosses streams. For a unique experience, the Burtonport Railway Walk offers an 8km traffic-free path where you can listen for a waterfall near Fiddler's Bridge.
Yes, the area around Glenevin Waterfall and viewpoint provides excellent vantage points for panoramic views, including towards Tullagh Bay and Binnion hill. The Owenwee River Waterfalls, visible from the road, also offer stunning views across the valley.
