Forming, for much of its length, the border between Herefordshire and Monmouthshire, the Monnow Valley is not only rich in historical features but is also arguably one of the most beautiful valleys in either England or Wales.

Rising in the black mountains, the River Monnow system can be split into three sections: the first, consisting the Olchon Brook, the Monnow itself & the Escley Brook, flowing south east; the middle section, flowing north-east from Pandy, where the Honddu joins from the south, to Llangua; finally, from the Dore, flowing south-east again to join the Wye at Monmouth. It is likely that the first section once drained south to join the Usk near Abergavenny, while the Dore appears to be the original headstream of the Lower Monnow.
Whether you are fisherman, rambler, cyclist, naturalist, bird watcher or historian you will find plenty to interest you in the Monnow Valley.
