Separating the Assam valley from the plains of Bangladesh, hilly Meghalaya – the ‘abode of clouds’ – is a cool, pine-fresh mountain state set on dramatic horseshoes of rocky cliffs. Cherrapunjee and Mawsynram are statistically amongst the wettest places on earth; most of the rain falls between June and September, creating very impressive waterfalls and carving out some of Asia’s longest caves.
