North Sikkim road journeys are long but you come across so many waterfalls on the way. The hours spent on the road were the highlight of the trip. I don't think there is any other place with this high density of waterfalls.

This is because the drive to North Sikkim is all uphill and this is the east Himalayan region, where it either rains or there is melting snow coming from many hills, to form tributaries which further form local rivers like Lachen River and Lachung River, which further connects to Teesta River which further connects to the great Bharmaputra River.
