Hi there - we are looking at two possible routes for part of our July 2016 UK road trip. We are looking for the most scenic route of course, like both historic and natural beauty. One route we are considering is up the coast through Dunbar and North Berwick, and detour back to Rosslyn Chapel. The other is to cut inland and travel through Jedburgh and Melrose heading to Rosslyn Chapel before arriving in Edinburgh. What our these roads/highways like? How do they differ? Scenery? A little more background - after leaving Edinburgh 4 days later, we will drive south through Peebles, Traquair, Selkirk, Hawick-Castleton and Carlisle - arriving at our final destination that day in Keswick (sorry, I know some areas are not part of the Scotland forum, but had to include it for logistical reasons!!).
Also, where is the best viewing of, and easiest access to Hadrian's Wall given our driving route? I have read Heddon-on-the-Wall is good and it would be on our route through Newcastle. The other would be close to Carlisle, but would that be too much of a detour given the length of our day coming from Edinburgh to Keswick? Thank you very much!
