Isolation is a dominant theme in the history of Bhutan. Perched among steep mountains and valleys in the Himalayas, Bhutan could only be reached on foot until it built its first roads in the 1960s. The last important statesman to visit Bhutan on foot was the first Indian Prime Minister, Jawaharlal Nehru, who trekked the 4500-metre-high Nathu-La in 1958. Now travellers can fly to the Paro International Airport, situated at a height of 2,225 metres (7300 ft). On this tour, we travel by land from India to the border town of Phuentsholing, one of the three land border areas to get into Bhutan.
