Hi,
We're intending to visit Skardu in end of June. Since we have 9 days available, we'll be skipping Hunza side. This is how our tentative plan looks like
Day1 - Isb to Naran
Day2 - Naran to Astore
Day3 - Stay in Astore and visit Rama etc.
Day4- Astore to Skardu via Deosai
Day5, 6, 7- Stay in Skardu and visit surrounding areas like kachura lakes, cold desert, manthoka waterfall, khaplu etc. Currently we're in process of arranging a visit to minimarg. Not sure if it'll be confirmed though.
Day8- Skardu to naran
Day9- Naran to Islamabad
If your plan is confirmed, then I'd suggest to book hotel rooms prior to your travel. For example, I checked yesterday and Wazir Mehel hotel in astore is almost fully booked for June.
Hope it helps
