Lak Lake is surrounded by Mnong villages and early morning mists hang above the calm waters and mingle with the smoke from the longhouses. The lake can be explored by canoes which have been painstakingly hollowed out from tree trunks. One can stay overnight at Buon Juin - a Mnong village - where it is possible to watch the working elephants take their evening wallow in the lake. The Northern mountains of Vietnam represent the country at its most wild and inaccessible. It contains some of its most awe-inspiring scenery and a fascinating mosaic of hill tribes.
