According to the World Travel & Tourism Council, India is expected to surpass its regional rivals, becoming the fourth-largest travel and tourism economy.

Although India has received a huge increase in international tourists than ever before, the real boost to its tourism economy is from domestic travel. Around 90 percent of travelers in India are Indians. Their most popular destination has been Nadu, the southernmost state of Tamil Nadu.

Tourism in India generated up to $230 billion in 2017, an increase of $21 billion from 2016. Steered by government subsidies and other incentives, five budget airlines launched 100 routes last year, making it even more appealing to travel for domestic tourists.

India’s natural beauty and wildlife is a huge attraction. But one concern is that the country’s weak regulations could allow some areas to lose what makes them special. For instance, some tiger reserves now no longer have tigers; some nature safaris have more buses than wild animals.

The most concerning problem is in Jammu & Kashmir, where a huge surge of tourists has flocked in to see snow leopards and landscapes featured in Bollywood films, creating a huge issue with waste. More than 30,000 plastic bottles are dumped in Ladakh each year. Waste is a problem throughout the Himalayas, and most is contributed by domestic travelers. Meanwhile, wildlife is harder to spot as Glacial melt is speeding up the desertification of the Himalayas. But no snow leopards means no tourists, and no tourists means no growth. Indian needs better support from the government to make sure that what brought it economy up will not crash it down.
