13. Nine Arch Bridge, Sri Lanka
An undoubtable highlight of our Sri Lanka in Depth tour is taking the train from Nanu Oyu to Demodara. As this strip of blue passes through green tea plantations, crossing the Nine Arch Bridge, it's a scenic (and striking) route from start to finish - much like the rest of the tour, which ticks off fishing ports, relaxing beaches and whale watching opportunities.
