The rolling hills around Munnar, South India's largest tea-growing region, are carpeted in emerald-green tea plantations, contoured, clipped and sculpted like ornamental hedges. The low Western Ghats scenery is magnificent – you’re often up above the clouds watching veils of mist clinging to mountaintops. Munnar itself is a traffic-clogged administration hub, not unlike a North Indian hill station, but wander just a few miles out and you'll be engulfed in a sea of a thousand shades of green.
