Extremely boggy and partially unridable for the first few miles from Little Vantage. Improves closer to Carlops. Would consider riding again after a prolonged dry spell.

Carter Bar is a renowned spot for tourists to stop and capture photographs along the English-Scottish border. Two purposefully placed marker stones, including one crafted by local Borders stonemason Eddie Laub, stand on either side of the A68. From this vantage point, you can admire the beauty of Upper Redesdale, the Scottish Borders (including Tweeddale), and the Cheviot Hills. Despite its elevation offering breathtaking views, the pass's height also makes it susceptible to snowfall, with the possibility of snow persisting into late spring and early autumn. Consequently, Carter Bar pass may experience periodic closures during the winter due to snow-related conditions.
