Bhutan has four major river systems flowing swiftly out of the Himalayas that are regularly fed by glaciers in northern Bhutan.
Bhutanese food is rice, generally a local red rice, served with either a little dried meat cooked with very hot chilies or red capsicum onum or a sauce made from chilies and local cheese. Bhutan food is generally know for it's simplicity but in reality it really is quite a specialty to marry the flavours and the spices... not to mention the effort involved in getting and maintaining the ingredients.
There are many ways to see Bhutan. A short trip for a week or less will introduce you to the world's last remaining Himalayan kingdom, with visits to the Paro and Thimphu valleys and perhaps an excursion to Punakha, the ancient capital.
