Vaphai
Vaphai is a village at the extreme east of Champhai district of Mizoram. Its original name was "Ivaphai", which literally means "Plains of the river Iva", referring to its original location in the river valley slightly west of its present location. The first syllable got dropped probably by elision in course of time. It is situated at an average altitude of 5,686 feet (1,733 m) above sea level.
