There are a few options for doing things at night in Peshawar. First, find a hotel that either has satellite TV so you can watch English TV. The Rose Hotels sat TV is excellent including Nat Geo, Discovery and ESPN. Second, read a good book or update yourself with some local history with your guide book. Finally, find a good restaurant with a big window on a high floor so you can people watch. It is possible to go out at night but Peshawar gets very dark at night and the staff at the hotel told me not to wander around outside at night due to the presence of Afghans refugees everywhere. Peshawar is safe during the day but I wasnt taking my chances at night. Overall, Peshawar is a great place to relax in your hotel at night.
