Distances are long, altitudes change fast, and the best days are the ones you build around road time rather than checklist tourism. The Tawang belt — Dirang, Sela, Jaswant Garh, Tawang Monastery — is the classic first trip.
Ziro Valley offers a different pace: Apatani villages, pine forests and music-festival energy in season. Further circuits toward Mechuka or the eastern districts need more days and careful planning.
Permits are part of the trip, not an afterthought. Start paperwork early and travel with a registered operator for smoother check posts.
