A bit of a long day, but a fantastic drive! I’ve always taken QL14E out of Kon Tum out to AH17 (Ho Chi Minh Road) and then up to QL14B into Da Nang. Anyone tried going on QL14G to Da Nang instead? How about taking the DT616 from between Tam Ky & Hoi An, which cuts more diagonally across the highlands? The map makes it look awesome!
Beautiful drive through the mountains, great scenery and pretty good road quality for the most part, though there are a few rough sections. Traffic is mostly light once you get out of Da Nang, but there are trucks, vans, and cars driving in the wrong lane occasionally.
