Apologize for late reply. I have shared few pictures. Let me complete the travelogue first.
Before sleeping, we asked hotel management about breakfast which was starting from 0830 hrs. We planned to leave hotel after breakfast by 0900 hrs to start our journey.
Plan was going to Nathia Gali Water Tanks and then either to go back to ISB via Murree or via Abbotabad. After Google Map searching and a bit googling about area, we decided to go back via Abbotabad as height decreases towards Abbotabad and a new place to be visited in this trip.
In the morning, we got up very early and had a beautiful scenic view from hotel room towards valley. Soon, this view dissolved due to heavy clouds immediately attacked and there was deep fog like situation. We were bit tense due to this but after sometime, it again cleared.
We had breakfast and left from hotel after checking out at around 0930 hrs and headed towards Ayubia road. Google Map was constantly opened with us so we need help from anyone else very few times.
Soon we reached Nathiagali but didn't find anything about Water Tanks. Upon searching from Google map, we found that track to Water Tanks is from Donga Gali which we left behind.
We had to go back to Donga Gali and turned towards Water Tank track. We took our ride up till the Water Tank spot near Hotel Mushkpuri and parked it.
Water Tanks are indeed a great and amazing place to visit. Scene was stunning. We captured few pictures when we saw clouds around us which were coming out behind the Water Tanks. Scene was simply unforgettable. Then, rain started which made is bit worried as driving in rain in hilly area for a new driver seemed to bit difficult. After few minutes of rain, we had to leave to start our journey again.
We started our journey and view between Nathiagali and Donga Gali was simply unforgettable when there were dark clouds beside road and even we could see clouds on road in front of us. It seemed that we were driving in clouds.
Such scenes can't be captured in camera as no camera can be compared with the ALLAH's blessing i.e. our own eyes, best of best of best camera in world. We could have said Subhan ALLAH only on such scenes. Indeed, ALLAH has given us each and everything.
After sometime, rain stopped so we happily continued towards Abbotabad. Road from Murree to Abbotabad is really enjoyable. I enjoyed it especially after Changla Gali as there is downwards slope only. 
Next stop was Harnoi, indeed a great place to visit. Weather was awesome and there was great rush of people. I visited this place around 7-8 years back and there was nothing there except a pool of river water in which people use to bath but now it has become a huge picnic place with hundreds, thousands of people enjoying. When we reached there, weather was very pleasant and we enjoyed staying there for 30-40 min. Indeed a nice place to visit.
Once we left this place and started journey to Abbotabad, after around 1-KM (from where we stayed at Harnoi), we say a beautiful artificial Harnoi lake also in which people were boating as well. Water color was so attractive and beautiful but we had already spent enough time at previous place so we left it without stopping here.
Next stop was Abbotabad. In abbotabad, we had plans to visit Ilyasi Masjid. We reached Abbotabad and then Ilyasi Masjid at around noon. It is built on mountain spring of mineral water having two beautiful pools which is worth seeing. Mosque overall has a serene view.
Mosque is famous due to pakoras of Ilyasi Masjid so we also tried these from shops adjacent to mosque and found those quite tasty. 
After visiting mosque, way back to ISB started with the help of Google Maps. We opted route via Havelian, Haripur, Wah, Hasan Abdal, Motorway and then ISB.
Google Map showed us short route via Wah but when we reached Wah Cantt gate via KKH-Wah Road, we came to know that we had to go back and has to come from full route via Hasan Abdal. Once we turned back and came back to other side of Wah Cantt via Hasan Abdal, we found that due to only 5-6 KM of Wah Cantt, we had to travel around 3-4 times of this distance to reach other side of Wah Cantt.
After this, we reached at Motorway and after some time, we reached in ISB, home sweet home, alhamdulillah safe and sound.
So, our memorable trip ended. I have added short summary of our route in first post. Hope you enjoyed it with us.
