Mizoram State Museum is a modest but worthwhile stop near the centre of Aizawl. Its displays cover traditional dress, musical instruments, household objects, weapons, and clan life, giving useful context before you travel deeper into the state.
The museum is not flashy, but it helps make sense of Mizoram's difference from mainland India. Look especially at the textiles and bamboo objects; they explain a lot about both the landscape and the practical elegance of Mizo design.
