IMPORTANT | NEED TO KNOW
Drink enough water. It is essential. It is also good to have mineralizing adds (Mg, Ca, K, Na) with you. Whichever camp you stay at you will get water for your next day trip.
Protect your head from the sun and heat. The best way is how the locals do so wrap your head with shawl.
Use UV filter cream on your skin. It is highly recommended to do that not only during summer period. Use at least SPF 30 so you can stay 4h on the sun before your skin will start to turn red.
Wear covered shoes. Choose comfortable covered shoes, especially if you go for trekking. If not you will need them as well if you want to climb a rock during simple jeep tour.
