I heard the trip to Paro is a white knuckle event.
cut and pasted the info below from Druk Air's website:
Nestling in the Himalayas, between Tibet and India’s Assam Plain, the kingdom of Bhutan offers a variety of climates, from the hot and humid jungles of the southern foothills to frigid snow-capped peaks in the north, which rise to 7,700 metres.
This country of 600,000 people is the last surviving Mahayana Buddhist state which has shaped the nation’s history, and it plays a vital role in everyday life. Bhutan is renowned for its undiluted culture and unspoiled natural wonders. Bhutan’s past is still it's present, its religion still a way of life. The last Shangrila.
Druk Air, the National Flag carrier of the Kingdom of Bhutan was established by a Royal Proclamation on the 05th of April, 1981. January 14th 1983 began the commencement of Druk Air’s operation when the German manufactured 18 seater Dornier 228-200 touched down at Paro airport bearing the Royal Flag of the Kingdom of Bhutan. On the Dornier, Druk Air operated to Calcutta in India and Dhaka in Bangladesh.
Paro is the only airport in Bhutan which is located in a deep valley at an elevation of 7300 ft above sea level. The surrounding hills are high as 16,000 ft and approach into Paro airport is entirely by visual flight rules. Due to the difficult operating conditions, operations with the Dornier 228 caused many delays and diversions. With the growth of traffic and the expansion of flights the need for a larger aircraft became necessary. After conducting numerous tests taking into account the difficult operating conditions the British Aerospace BAe 146-100 was selected and started operations in November 1988. Within a short span of its introduction the network of Druk Air increased to link Paro with New-Delhi, Bangkok and Kathmandu. From two destinations in 1983 today Druk Air operates from Paro four times a week to Bangkok and Calcutta, twicw to Kathmandu and Delhi and once a week to Dhaka and Yangon.
Maybe the smallest national carrier in the world, Druk-Air has a fleet of two BAe-146 aircraft. An international flight crew and hostesses trained by Thai Airways International give the airline its credibility and charm.
Druk-Air is the only airline that serves Paro. So all visitors to Bhutan are initiated into the kingdom in its care. The flight into Paro is one of the most spectacular in the world. Whether flying along the Himalayan range from Kathmandu or over the foothills from Calcutta or Dhaka, each flight is mesmerising aeronautical feat and offers an exciting descent into the kingdom.
Sounds like fun!
