Sarn Sabrina Walk

40 km / 25 miles

Based on the Celtic myth of Sabrina, a water nymph said to inhabit the waters of the River Severn, we have created a 25 mile circular route called the Sarn Sabrina and a shorter 12 mile route called the Semi-Sabrina.

The Sarn Sabrina is a walk of 25miles (approx. 40km) that leads out of Llanidloes following the national trail of Glyndwr’s Way. Leading up past the Van Pool, the path opens up extensive views of the Llyn Clywedog and the surrounding countryside, before following the shoreline of the lake to the borders of the Hafren Forest and Cwm Biga Farm. Climbing up through the Forest to the slopes of Pen Pumlumon, the trail then visits the source of the Severn at 620m above sea level. Descending through the forest along the Severn Way long distance path, the trail next takes to the watershed of the Severn and the Clywedog, enjoying stunning views of the surrounding countryside before arriving back in Llanidloes.

The Sarn Sabrina Walk is both a one day challenge walking event which held its inaugural walk in 2006, and a trail that can be walked over a number of days for you to savour the beautiful views the route encompasses.
