OK. Faraz.
last suggestions, Ascend from one side and descend from Other Side. It will be a good option, You can see more areas. From Nathia Gali side you can also see the Lalazar Wildlife Park.
From Mukshpuri Trek/Top try to spot Jehlum river, Meeran Jani, Nathia Gali, Ghora Dhaka (Ayubia Chairlift hill), Khanaspur, Changla Gali Top etc.
Nathigali and Dunga Gali distance is just 4 km via road. If you start from Nathia, and end at Dunga Gali, then you can take any transport from Dunga to Nathia, If your stay is at Nathia Gali.
Take with you water, tang/energile, optionally packed lunch to be taken at top.
Don't drink plenty of water at once. Drink little little water. Its better to take tang/energile instead of plain water.
Don't take long rest session before reaching the top. Just small rests, and start your journey again, before the body gets cooled.
Gallies are just deserted in Ramadhan. Waisy rozay k sath such trekking, i don't think is recommended.
Take Care. Enjoy your time.
Share trip report and pics also. Thanks.
