Cherrapunji (also known as Sohra) holds the record for the world's highest annual rainfall — over 11,000 mm in a typical year, with a single-year record of 22,987 mm. Despite being in Meghalaya rather than Assam proper, it is easily visited from Guwahati and frequently included in trips to the northeast.
The town sits on a plateau in the Khasi Hills, with dramatic views south over the plains of Bangladesh. Warm, moisture-laden air off the Bay of Bengal hits the hills and is forced rapidly upward, generating near-constant cloud and rain for much of the year. The best time to visit is October to May, when skies occasionally clear and the waterfalls fed by the monsoon are still flowing strongly.
The most unusual attraction is the living root bridges — footbridges made by training the aerial roots of rubber fig trees across rivers and gorges over many decades. The Khasi people have built dozens of these in the valleys below the plateau; the double-decker root bridge near Nongriat village is the most celebrated, reached by a steep descent of around 3,500 steps each way. The waterfalls ringing the plateau are extraordinary: Nohkalikai Falls is the tallest plunge waterfall in India, while the Seven Sisters Falls drops 315 metres in seven parallel streams. Mawsmai Cave offers an accessible glimpse of the limestone cave systems beneath the plateau.
Cherrapunji was founded as a British administrative centre before being overshadowed by Shillong. The strong Welsh missionary presence left a lasting Christian imprint on the local Khasi community.
