So you've seen the world's largest salt flats, but the Rann of Kutch in Gujarat, India, is the world's largest salt marsh and desert! What's a salt desert? During the monsoon season, the Rann plains are flooded with water from multiple rivers and sea water that's blown in. But, come winter and dryer seasons, the water evaporates creating the salty desert that almost seems otherworldly.
The Rann covers around 10,000 square miles. Thousands of years ago, the Rann was considered part of the Arabian Sea, but geological changes have severed ties. Now, some sea water from the Gulf is blown in because of the strong monsoon winds. The best time to visit is definitely during the winter, but keep in mind that temperatures can get pretty chilly.
Among other draws, the Rann is a breeding ground for flamingo and pelican populations during the winter (there's even a section that's called Flamingo City). Labeled as a birdwatchers paradise, the region is a must-see if you're hoping to catch a glimpse of the beautiful birds.
