Getting there & away
To get to Derawar Fort take a bus to Dera Nawab (Rs 35, one hour) and from there hire a minivan (seating six) at Abbasi Chowk (Rs 60, two hours). A taxi from Bahawalpur costs about Rs 4000 for the day (including waiting time).
The best time to visit is between November and February, or early morning or late afternoon at other times of year, to avoid the noon heat. Take water and snacks with you.
