India s Northeast States, dangling way out on the edge of the map and the national perception, are strictly for explorers who want something different from their India experience. These remote frontier lands, where India, Southeast Asia and Tibet meet, are a collision zone of cultures, climates, landscapes and peoples and are one of Asia s last great unknowns. It s a place of rugged beauty where uncharted forests clamber up toward unnamed Himalayan peaks. It s a land of enormous variety where rhinoceros live in swampy grasslands and former head-hunters live in longhouses in the jungle. And it s an adventure in the truest sense of the word.

boat is met by a bus to Pasighat in Arunachal Pradesh. Ferries lake kalamalka can carry just two jeeps. There s little shelter and the journey takes around eight hours (5 hours downstream), so bring an umbrella, water and sunscreen. The journey can be quite an adventure with the boats bouncing off the ever-shifting sandbars (and sometimes not bouncing off them!) and with brief stops en route giving glimpses of isolated riverside hamlets. Exact departure points depend on the Brahmaputra s water level.

374 bird species have been recorded in the park, including such rarities as the whiterumped vulture (which may now be extinct in the park), greater spotted eagle and the white-winged duck. Of the big mammals, wild elephants are present as are numerous deer species and a few rarely seen tigers. However, for many mammal-spotting naturalists, the park s most exciting resident is the critically endangered dwarf hog, which, after many years of absence has recently been returned to the wild thanks to a successful captive breeding project run by the Durrell Wildlife Conservation Trust (www.durrell.org). Park fees include the compulsory armed guard. Access is from Potasali, 2km off the Tezpur Bhalukpong road (turn east at one-house hamlet Gamani, 12km north of Balipara).
