After a few days in Phong Nha, I continue my journey through the rest of Vietnam. Time is running short if I want to follow up on my plan to loop the Tonkinese Alps in the northwestern part of the country. Early in the morning, I am tying my backpack down on the motorbike rack and drive as far as I possibly can; 450 kilometres of dirt roads in 11 hours of heat. Definitely the longest stretch I have been driving in one single day on my journey so far. Occasionally, I stop for a quick Vietnamese coffee and a delicious Vietnamese Bánh Mì. About 100 kilometres before Cam Thuy, I cannot resists to stop and watch the sun setting between towering limestone karsts surrounded by green fields.
