The 12-day "India: Kaziranga & Brahmaputra River" will include a cruise on the 58-passenger Mahabaahu. Guests will sail along India's Kaziranga National Park -- known for one-horned rhinos, hoolock gibbons and South Asian river dolphin -- in the Assam region of the country.
Passengers will visit remote villages, tea plantations and see wildlife. They will also get views of the Himalayas during the five-night cruise portion of the itinerary.
There are six departures (two in 2017, four in 2018), with the first taking place on March 30, 2017.
"River cruising is more popular and rewarding than ever. People also crave more meaningful interaction with exotic cultures and once-in-a-lifetime opportunities to observe rare and beautiful wildlife," said Bill Robison, IE's director of program development. "This new expedition allows guests to be among the first to explore a remote and evolving corner of our world."
The Mahabaahu's dining room serves a menu of both Indian and continental cuisines. There is a swimming pool, library and spa onboard.
Prices for the 12-day Brahmaputra River cruise start at $6,698 per person (based on double occupancy), and include accommodations, excursions, transfers, tips to service staff and bottled water.
