Tourism in Bhutan began in 1974, when the Government of Bhutan, in an effort to raise revenue and to promote the country's unique culture and traditions to the outside world, opened its isolated country to foreigners. In 1974, 287 tourists visited Bhutan. Since then the number of tourists visiting Bhutan has increased to 2,850 in 1992, rising dramatically to 7,158 in 1999.[1] By the late 1980s tourism contributed over US$2 million in annual revenue.
