Generally speaking, a 15-day tour is appropriate, and the best time to do it is in May, June or October. Here are some tips:

1. Be prepared for altitude sickness. Have some glucose, brown sugar and medicine in case of emergency. Make sure you don’t set out if you have a cold.

2. Rent a SUV so that you can traverse some rougher roads.

3. Book your accommodation in advance in case of unavailability.

4. Check up road conditions before your trip.
