The road definitely less traveled. TL217 from Bao Lac to Meo Vac. As the title says, it took us a good seven hours to complete this 70km ride. Extremely difficult roads, you will go where most have never been. Not recommended unless you are an extremely experienced rider, also best not to be alone. You will do a river crossing by bamboo boat and most of the journey will be narrow and windy dirt roads. If your bike breaks down, you are pretty much in trouble. Don’t expect anyone to be passing by. You can read more about the trip that made me want to cry here.
