|Post town:||Barnard Castle|
Boldron is a village in the North Riding of Yorkshire and within the Pennines. It is just north of the A68 trans-Pennine trunk road, between the Greta Valley to the south and Teesdale to the south. A lane runs down to the latter dale to Startforth, across the River Tees from Barnard Castle, Boldron's nearest town, which stands across the river in County Durham.
