Tourists wanting to combine to visit to Bhutan with Sikkim & Darjeeling (or other places in India) can enter Bhutan by surface road through the border town of Phuenstholing.  This is the only other entry point to Bhutan other than flying into the Paro airport. Visitors can also fly into Bhutan and exit by road through Phuentsholing or vice versa.

Phuentsholing lies approximately 170 km east of the Indian national airport Bagdora, nearby a Darjeeling, a hill station.  The road leads to the northern Indian tea plantations through endless turns, hair pin bends and daring stretches carved into the mountain rock via Chukka to Thimphu, Capital of Bhutan.  The travel time for 275 km stretch can be more than 7 hours.

For those travelling to eastern Bhutan there is an option to exit out of the country through the border town of Samdrup Jongkhar to Guwahati Airport in Assam of India.  Only exit is allowed from this point not entry into Bhutan. From Guwahati there are flights available to Calcutta and Delhi.
