Barnard Castle, a market town in County Durham’s bucolic Teesdale, is a great example of this. It occupies the spot of a former Roman fort that once spanned the river. Overlooking the river, the castle’s mediaeval ruins are impressive. Cobble streets, yards, and back roads have been a feature of this town since its original layout in the 12th century, when it earned the endearing nickname “Barney” from locals and tourists alike. The Bowes Museum is conveniently located, and a day spent exploring the museum’s stunning structure and engaging displays would be well spent. This charming market town is conveniently located near some of the best hiking and biking terrain in the country, including the Lake District, the Pennine and Teesdale Ways, the River Tees, and the beautiful waterfalls at High Force.
