Old Rectory Walking
There are plenty of hiking trails to explore perched above the Usk Valley overlooking towns of Crickhowell and Gilwern. Llangattock Hillside is a popular scenic spot and offers thechance to explore the limestone quarries along gently sloping quarry tracks. Today the limestone cliffs that form the Llangattock escarpment dominate the skyline in the Crickhowell locality of the national park. Most would agree that it is a striking attractive feature of the landscape. Yet it is not a natural feature rather the results of extensive quarrying in the 18th and 19th centuries. Today the Llangattock escarpment is a favourite locality with cavers from across Europe. There has been no quarrying on this escarpment for nearly 60 years and nature has largely reclaimed the landscape as its own. The quarrying process in effect sectioned the cliff face and in so doing uncovered an entrance to one of the longest cave systems in the United Kingdom with over 12 miles of passages. The western section of the escarpment is now designated as the Craig Y Cilau National Nature Reserve.
