Being on the Eastern Himalayas, Arunachal is home to some of the tallest snow-peaked mountains in the world. Trekking expeditions to these peaks offer some of the best experiences in the world, yet are the least visited ones. For the wonderful experience of trekking, there are a few destinations in the world that would match the trekking routes of Arunachal Pradesh. The best trekking season in Arunachal Pradesh is from October to February. The most interesting as well as challenging trek in this region is around Tawang Chu. This trek starts from Jong, the bus-head in between Se- la and Tawang. From Jong to Mago, the trek route passes through a wonderful jungle studded with magnificent waterfalls.

The Major Trekking Routes in Arunachal Pradesh
For a driving and daring leisure seeker, few destinations in the world would match the dimensions of Arunachal Pradesh.
Experience The Wilds of Arunachal
Arunachal Pradesh is the northeastern tip of India with its borders touching China, Bhutan and Burma (Myanmar). Its endless variations of scenic beauty are the first to greet sunrise in the country. The state is proud of having more than 500 rare species of Orchids. Its rivers are ideal for angling boating, rafting and its rugged terrain is suitable for trekking, hiking and holidaying in a serene atmosphere. The sixth Dalai Lama was born on the soil of Arunachal Pradesh and the 13th found refuge and safety here.
Southern Flank
The southern flank of the Arunachal Himalayas is visible from the plains. This part of the range includes peaks as secluded as Kangto, among the highest and unconquered peaks in the world. A puzzling approach and thick jungle has kept these summits virtually off limits to mountaineers. Five of the main tributaries of the Brahmaputra River rise in these ranges: the Kameng, Subansiri, Siang, Lohit and Tirap. Geographical seclusion has made the people of these valleys self-contained. Cross communication is a relatively recent phenomenon. The total population of the state is small and it retains much of the original forest cover.
Se La Pass
The western most district is west Kameng, named after the Kameng River, which drains the basin of Groi Chen and Kangto peaks. From the inner line check post at Bhalukpong, 52-km from Tezpur the road winds through the Tipi Orchidariurm to Bomdila. It crosses the crest of the Se La Pass at 14,000-ft finally reaching the Mahayana sect Buddhist monastery at Tawang. These are the environs of the Bailey trail the old border trade route over Tukung La from Tibet first used in 1913 by the British surveyors.
Margherita Railhead
This circuit covers the well-known Namdapha National park in the Tirap 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 Margherita, also reached by National Highway 38 from Tinsukia. Coaches continue up to Miao for entry into the park. Unique in that its elevation varies between 200 and 4,500 m, the park is also unmatched as the home to four large cats: Tiger, Leopard, Clouded Leopard and Snow Leopard.
Thick Forests
Using Pasighat as the base, where the Brahmaputra enters the plains, a reasonably good road meanders up-river through thick forest. Neat settlements at Yembung, Pangin and Boleng lead to the Siamang Bridge, 110-km from the base. The route is a photographer's delight. Here also lie promising tracts for catch and release Mahaseer angling. Again for Pasighat, aside from the Dibrugarh ferry, there is another access via the 415-km drive from Tezpur roughly parallel to the north bank of the Brahmaputra.
Recently opened Tourist Routes in Arunachal
Certain tourist routes have recently been opened in Arunachal Pradesh. The first of these routes originates at Itanagar and links up to Ziro in the center of the state 150-km away, at an altitude of 1,754 m in the resplendent Apatani plateau. The trail pushes farther east and north, crossing Sunansiri River at Daporijo to reach along. Here, one meets the peripatetic harbinger of Mansarovar, the Siang, still within its white water section. In 1991, an Indo-Japanese team rafted the length of the river in India, putting in near Geling in west Siang district, just a few km short of the Indo-Tibetan border. The final section of this circuit goes down to Pasighat and re-enters north Assam before returning to Itanagar. Day excursions include Ganga Lake, the state museum and a ride on the elephant back to the salubrious camp on the nearby Dikrong River.
Permit For Indian Tourists: 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. These can be filed with any Indian Mission overseas, the Home Commissioner of the state in Itanagar or its Resident Commissioner in Delhi
