From the border town of Sust, we had travelled southwards by boat towards Gulmit for a quick lunch pitstop at the Marco Polo Inn (visited by Prince Philip and the Aga Khan apparently) and then onto Karimabad in the Hunza Valley. There has been a landslide on a part of the KKH and so there was no choice but to go via boat down the turquoise waters of the Hunza River, flanked by sharp jutting cliffs on either side. Alongside human passengers (us), boatloads of car tyres and other goods from China were being carried down tbe river and unloaded at Karimabad to be further transported south.
