Bhutan remained isolated until the early 1960’s. To reach Bhutan, you had to travel by foot and via India and Tibet. Today, however, carefully planned economic development has made Bhutan more accessible through a network of roads, one international airport and two domestic airports.
Everyone requires a visa to enter the country via road and air. Indian, Bangladeshis and Maldivian nationals can receive a visa on entry, a passport or voters card are acceptable on entry.
