The trail pushes farthest east and north, crossing the Subansiri river at Daporijo to reach Along. Here we meet that peripatetic harbinger of Mansarovar, the Siang - still within its white water section. The final section of this circuit goes down stream to Pasighat and re-enters north Assam before returning to Itanagar. The second tourism circuit covers the well known Namdapha National park in the Triap district near the east end of the state, not far from the Burmese border. The designated entry and exit point on this circuit is the railhead at Marghertia also reached by National Highway 38 from Tinsukia.
Coaches continue to Miao for entry in to the park.
Uniqueness is that the elevation varies between 200 and 4500 meters. An Indian National intending to visit any part of the state may obtain an Inner Line permit from the Arunachal Government office in Delhi or Itanagar. For the permitted areas, the total time allowed for the foreigners is 10 days. The usual stipulations of entry permit, group size and advance application also hold good.
