Bus: This is the main way to get around the Himalayan north, the only choice in many places. The winding roads and steep slopes make for some nerve wracking moments; but the views more than make up for it.
Train: Being a mountainous region there are very few rail lines. However, there is a "toy train" service that connects Kalka and Shimla. In its day, this single gauge line was a remarkable engineering feat, but now it makes for a slow and beautiful tourist route.
