Central Highlands - Vietnam

From the Lonely Planet Guidebook:  "It's easy to get off the beaten track in this wonderfully scenic part of the country.  Only Kalat makes it on to most tourists' radars, meaning that the rest of the region still allows an element of adventure.  This is a great part of the country to see on the back of a motorbike - stopping at will to admire an amazing mountain view, to explore a wild waterfall or to interact with villagers from the local hill tribes.  The cooler climate also makes a good respite for those not used to tropical climates.
