Honddu

The Honddu is a river in Wales that flows through the county of Powys. It rises in the Brecon Beacons National Park and flows southwards for approximately 25 miles before joining the River Wye near the town of Brecon. The river's name is derived from the Welsh language, with "honddu" possibly meaning "old" or "ancient."

The Honddu Valley is known for its scenic beauty and agricultural land. The river passes through several small settlements including Aberhonddu, which is the Welsh name for Brecon. Along its course, the Honddu receives water from various tributaries including the Tarell and the Grwyne Fechan.

The river has historical significance, with evidence of human settlement along its banks dating back to prehistoric times. During the medieval period, watermills were established along the Honddu to grind grain for the local population. Today, the river is popular for fishing, particularly for brown trout and grayling.

The Honddu is an important part of the local ecosystem, supporting various species of wildlife including otters, kingfishers, and herons. The river and its valley are designated as part of the Brecon Beacons Special Area of Conservation, recognizing their ecological importance.
