Thoda Ladakh ka travel partner jugad ne mein busy hun. September 18th . By any chance are you planning Ladakh during that time? I am travelling solo.
The only issue with Dapo is people are not very friendly there, specially after evening, when they all are delightfully high. Apart from it it has many many advantage.
1) Along to Dapo route is very beautiful.
2) It will save atleast a day from you.
At the same time keep your option open, with multiple places mentioned in your ILP. When we were there , an airforce official has offered us a free fly to Assam in their jet- who knows whether you will also get the same offer.

Just mention Along-Dapo-Ziro(any any other place that you want to visit) in your ILP. And if you are planning to apply it from Arunachal Bhawan Kolkata, it wont be difficult- the guy sitting there dont even know Arunachal Map ( He never heard the name of Mechuka, and wasn't even aware of there is any place in North Western part of Along). I had a long discussion with him and suggested him to visit atleast Ziro once.
Any doubt!!!! It will atleast take 2020 for sure.
Its been almost more than 18 months now , since we are back from Mechuka, and it left me spellbound , when I still receive calls from the villegers of Mechuka along with Gebu.
