While the Lohit, Tirap and Dibang valleys can be accessed from Dibrugarh (Kolkata-Dibrugarh), it is best to head for Bomdila-Tawang from the Tezpur side and Itanagar-Ziro-Aalo-Pasighat from the Lilabari (North Lakhimpur) side. A visit to the state can be divided into four distinct parts: the Bomdila-Sela-Tawang region, Itanagar-Ziro-Aalo-Pasighat, Roing-Anini and Namdapha-Tezu.
