Day 1:
* Start, early morning, from ISB and arrive at PTDC's motel in Miandam... Spend a night there. And, take good rest. Expect a bumpy day ahead.
Day 2:
* Leave for Kalam at around 7 AM. You'll arrive in Kalam at around 10 AM. Visit Utror valley and go see Kandol lake, if possible. I've not seen it but it may be a good place to visit. Stay, in a tent, in Kalam forest. There are excellent tents placed there.
Day 3:
* Visit Usho valley. Go to see Saifullah & Mahodand lakes. Spend a night in Kalam again.
Day 4:
* Arrive at Malam Jabba and spend a night there.
Day 5:
* Head to White Palace. And, from there back to Islamabad.
Discuss this plan with someone who's more familiar. This is just my opinion.
