Nice Planning.
From Fizza Ghat, you can go to Malam Jabba which is very beautiful place, you can even spend a day over there.
It is also called Mini Switzerland of Pakistan (it looks like Switzerland in Winter season), I recommend Malamjabba don't miss it.
Day 1, Visit Fizza Ghat Park, boat riding, and site seeing.
same day you can also go to white Palace, Museum, Saidu Sharif etc. (by car)
Day 2, Go to Malam Jabba, and its surrounding. ( chairlift is also there )
Day 3, Include Miyadam to see Trout Farm while going to Madyam/Behrain.
Day 4, Ushu, Glacier, Mahoodand / Saifullah Lake can been seen in one day. ( lakes are soooooo beautiful )
Day 5, If you have enough energy to walk on hilly areas for 2 to 3 hours then go to Katwal Lake from Kalam.
(Around 1.5 hours by road & 2 to 3 hours by walk to reach Katwal Lake & same on return is required).
Try to start your day tour early in the morning ( to enjoy well and to cover most of the places )
Rest, experts will advise the best.
