This is a great route. It's low on traffic until you reach the New Abbey Rd. It has many hills throughout and the descents appear just when you need them to. Between the 'Old Military Rd' not long before you join the 'Dalbeattie Rd' there is a descent you can gain incredible speed on. Also on the 'Whinny Hill' descent you can fly, but watch out for ignorant motorists overtaking, forcing you into the side of the road, even if your riding 40mph plus.

There are some seriously nasty pot holes which may be hidden in shadow on the run in to New Abbey. Take care.
