Trek along Buddhist trails and Monpa villages that boast of ancient monasteries, chortens and mani walls. The Sela-Tawang Trek is another beautiful, long and popular trek in Arunachal Pradesh. You get to see the Tawang and Khinme monasteries, Urgeling - where the 6th Dalai Lama was born, Sange Ryabgelling shrine while also passing through streams and valleys dotted with rhododendrons, oak and pine trees as well as rare birds. The trek is done in stages and also uses the motorable road because it's so long. The Gorichen Peak (Arunachal's highest) looks breathtaking from here. The trek also takes you through glacial rivers and pristine lakes.
