Cherrapunji
One of the most extraordinary sights in India — a naturally formed bridge made of living rubber tree roots, carefully trained over generations by the Khasi people into a fully load-bearing double-decker crossing over a crystal-clear jungle stream. The 3,500-step trek down through dense rainforest is challenging but deeply rewarding, and the bridge itself is unlike anything else you will encounter anywhere in the world.
Start before 8 AM to avoid afternoon heat and crowds. The return climb is steeper than it looks — carry electrolytes and at least 2 litres of water per person.
