Tourism in Bhutan began in 1974, when the Government of Bhutan, in an effort to raise revenue and to promote Bhutanese unique culture and traditions to the outside world, opened its isolated country to foreigners. In 1974 a total of 287 tourists visited the Kingdom of Bhutan. The number of tourists visiting Bhutan increased to 2,850 in 1992, and rose dramatically to 7,158 in 1999. By the late 1980s tourism contributed over US$2 million in annual revenue. Potential visitors to Bhutan obtain visas through a Bhutanese embassy or consulate in their home country.
