Getting to Dumfries and Galloway by road:
Dumfries and Galloway is located in the south western corner of Scotland. It’s an easy drive from most cities in the north of England and central Scotland.
The M6 is the main route into Scotland and connects directly with the A74/M74 which you will join (or leave, depending on which direction you are coming from) at Carlisle.
Dumfries is around an hour from Glasgow and 45 minutes from Carlisle.
When you are in Dumfries and Galloway, the main road linking the east side of the county (Gretna) to the West side (Stranraer) is the A75. It takes about 2 hours (96 miles). There are lots of smaller A and B routes taking you around the region, but as you are mainly travelling through countryside be very aware of the windy roads, some of which are often also occupied by sheep and cattle!
