Nestled in the Cambrian Mountains near Llanidloes, Hafren Forest offers one of Britain’s most scenic and accessible boardwalks.
Far from the bustle of coastal promenades, this tranquil woodland trail follows the River Severn through moss-draped trees and cascading waterfalls, earning its reputation as the UK’s most beautiful inland boardwalk.
The Cascades Walk is the star attraction—a 0.9km (0.6-mile) accessible trail that begins at the Rhyd-y-Benwch car park and descends gently to a raised boardwalk along the riverbank. The route culminates at a viewing platform overlooking a series of shallow waterfalls, before looping back through the forest on a smooth, well-surfaced path. It’s ideal for wheelchair users, families, and those seeking a peaceful stroll immersed in nature.
Why Go?
Hafren Forest is a masterclass in understated beauty. The boardwalk offers a cinematic view of the River Severn’s early journey, framed by towering conifers and the melodic rush of water. It’s a haven for birdwatchers, with sightings of red kites, woodpeckers, and even ospreys during breeding season. The forest’s quiet charm and lack of commercialisation make it a rare gem for high-net-worth travellers seeking privacy and authenticity.
What to See and Do
Beyond the boardwalk, Hafren offers five waymarked trails ranging from 30 minutes to five hours. The Severn-Break-its-Neck Trail (2.3km) leads to a dramatic waterfall, while the Blaen Hafren Falls Trail (6km) winds deeper into the forest. For seasoned hikers, the Source of the Severn Trail (13km) climbs to the river’s origin on Pumlumon’s slopes. Picnic benches and viewing platforms are thoughtfully placed throughout, perfect for sketching, photography, or quiet reflection.
Distance and Parking
The Cascades Walk is a gentle 0.9km loop, with longer trails branching off. Rhyd-y-Benwch Car Park is the main access point—free of charge, but limited in capacity. Arrive early to avoid congestion, especially on weekends. Note: toilet facilities are currently portaloos due to renovations, and there are no bins—visitors are encouraged to take rubbish home.
Hafren Forest’s boardwalk isn’t flashy—it’s quietly spectacular. For travellers who value serenity, ecological richness, and immersive natural beauty, this woodland escape offers a rare kind of luxury: space to breathe, reflect, and reconnect.
