Arckle Beck is a small stream that flows through the North Yorkshire countryside. It is a tributary of the River Swale and is approximately 10 miles long. The beck rises in the hills above the village of Grinton and flows through the villages of Reeth and Low Row before joining the River Swale near the town of Richmond.
The beck is a popular spot for fishing, with brown trout and grayling being the most common species caught. The surrounding countryside is also popular with walkers, with many footpaths and bridleways crisscrossing the area. The beck is also home to a variety of wildlife, including otters, kingfishers, and herons.
The area around Arckle Beck is steeped in history, with many ancient monuments and buildings to explore. The nearby village of Reeth is home to a museum dedicated to the history of the local lead mining industry, which was once a major source of employment in the area. The ruins of the medieval fortress of Castle Bolton are also nearby, as is the impressive Aysgarth Falls, a series of waterfalls on the River Ure.
