Cherrapunji & Mawlynnong (Meghalaya)
What it is. One of the wettest places on earth + the village known as "Asia's cleanest".
Why visit. Nohkalikai Falls in full flow, the double-decker living root bridge, and Mawlynnong's bamboo-swept lanes — completely different from any other Indian destination.
Tip. Base in Shillong (3 hours away). Hire a local Khasi guide for the root-bridge trek; the path crosses rivers that need real footing in monsoon.
