Altitude and Acclimatization:

Accommodation and Booking:
There's a wide range of accommodations from luxury hotels to more budget-friendly options. It's advisable to book in advance especially during peak tourist season.

Clothing and Essentials:
Lightweight, breathable clothing is recommended due to the heat. However, more conservative attire is appropriate when visiting religious sites. Sunscreen, hat, and sunglasses are essential. Pack comfortable shoes for walking and visiting archeological sites.
