The time to come to Nepal for rafting depends upon the river that you want to raft; you can see from each itinerary that each river has a peak time for rafting. Generally speaking, however, the best time to come to Nepal for rafting is from mid September until the end of November, when the weather is fair and the majority of rivers are open. March through to April is also a good time when the rivers are fed from the snow melt. Some of the lesser grade rivers can also be run during the early monsoon months of June and July. Please refer to each River for its peak time.
