"Jhapa, the southeasternmost district of... " a Jhapa Travel Page by Saagar

Jhapa is in some ways the most exotic place in Nepal. Three countries meet up here; a narrow corridor of India separates Nepal and Bangladesh, and Bhutan isn't far away, either. The population is quite an exotic mix, too, with Santals as perhaps the most interesting group compared to other parts of Nepal.

The vegetation is lush, with a mix of the open Terai sal forest, palm trees lining canals and creeks and more dense, tropical vegetation interspersed with tea gardens.

Most foreign travellers to Jhapa either visits as aid workers or tourists in transit. Jhapa is host to some big Bhutanese refugee camps. The Kakarvitta border post here is the last piece of Nepal before Darjeeling and the east; Assam etc. Jhapa is the district south of the tea hills of Ilam and Panchtar. You can also get from here to the Kanchenjunga area if you do not want to fly into Taplejung. It's a curvy road first, then bumpy second to reach Taplejung.

Contemplate the beauty of the flat agricultural landscape below the green hills of Ilam, and the peoples lives here.
Fantastic people-watching: you have the widest assortment of peoples on display here; being tillers of the soil, labourers in the bazaars, travellers to/from India, pot-bellied Indian babus, slim Santals and just about everybody else.
See the tea gardens here; since the maoist insurgency it seems as if there is a guerilla behind every second bush, so organised tours are not run anylonger. But you can look and probably get a private show of facilities if you ask.
Shopping; the bazaars here have a lot of stuff for sale to bus travellers and locals; much crookery and what not from India. For the international backpacker the bazaar will have limited scope apart from photograpy - very nice and colorful.
Be humble in Jhapa; this is not a rich part of the world and rampant poverty is at first hand here. With that comes that particular spillover from Bihar and West Bengal/India - casteism and dacoitry/banditry - rife here i the east, mainly as cross-border raids. Beware of safety at night.

Transit; most people are in a hurry to get on with their travel; Jhapa's main bazaars are not relaxed rural affairs, but catering to transit passengers. It's loud and dusty. Tickets, porters, last minute shopping, shouting and banging transport wallahs of all kinds.
The East-West highway intersects Jhapa. At the eastern end is Kakarvitta, the border crossing into India. 11 km or so from Kakarvitta, 3 km south of the EW highway is the town Chandragardi and the Bhadrapur settlement with the easternmost airport in Nepal. No other border crossing is open for foreigners.
From the Indian side you can catch a bus or a combination of bus/train via Siliguri to Darjeeling, or generally connect to the indian railway network. With a guide it is easy to get across the Indian corridor to the Bangladesh border and continue toward Dhaka.
