North east India is the most beautiful and unexplored part of india. There is so much to see and do in every region. My itinerary comprises of Darjeeling and Sikkim.
Though there are direct flights to Sikkim but if you want to cover Darjeeling then you need to go through Westbengal to reach there. There are direct flights to Bagdogra Airport from delhi and other parts of country.
Traveller Tip: Visit Darjeeling first and then Sikkim. (If you visit sikkim first you probably wont like Darjeeling). Book a luxurious taxi for your complete trip. This will save cost and time. (will cost around 25000 for Innova for 7 days)
