Two jeeps on a steep and rugged mountain road in the Kali Gandaki valley, between Tatopani and Jomsom, in the Annapurnas (Nepal)
Those are the only cars we crossed on this road during the entire day. Looks like they were carrying tourists or trekkers. Other motorized traffic we saw was a local bus, a truck and a couple of other motorbikes, that's all.
It is better to carry all the tools and spare parts you may need in case of puncture or break-down, if you don't want to spend a long time waiting for help on this remote road.
