Cab rentals cost around INR 4000-5000 per day and a total of INR 28,000-35,000. Alternatively, public transportation is available, but not very frequent, comfortable or reliable as private transportation.

For instance, Arunachal Pradesh offers various trekking destinations and hill stations such as Tawang and Ziro.
