Guys !!
First post, and dont want to put in a lot of questions

And since so much info is already available, dont want to create yet another thread !
So, I am right now in a process to make an plan - from Delhi to Leh to Delhi.
Total Available Days - 2 weeks off + Sat/Sun = 15 days total.
Period - tentative right now, probably 11th June to 25th June ( hope by this time rains/loose slush would be no more ? )
You never know with the weather. But road conditions might be tough and water crossings might be a challenge. September is always the best time to go. But June is ok.
Day One - 11th June 4AM start
Delhi to Pathankot - 500kms
night stay @ Pathankot
(or maybe stretch to Jammu ? )
Yes you can, mostly plain terrain, good roads. Depends on how long you can drive.
Day Two - 12th June
Pathankot to Jammu - 110kms
Jammu to Srinagar - 300kms
night stay @ Srinagar
Day Three - 13th June
One day rest @ Srinagar
Day Four - 14th June
Srinagar to Sonmarg - 85kms
Sonmarg to Drass via Zozilla Pass - 60kms
Drass to Kargil - 60kms
Night stay @ Kargil
Day Five - 15th June
Kargil to Lamayuru - 110kms
Night stay@ Lamayuru
Can go directly to Leh(roads are really good, won't take much time)
Day Six - 16th June
Lamayuru to Leh - 125kms
Night stay @Leh
(Use this day for Nubra valley beyond Khardung La)
Day Seven (17th June) @Leh - Shanti Stupa, Leh Palace, Main Market, Polo Ground
Day Eight (18th June) @Leh - Leh – Phyang – Khardung La (40kms) - and back to leh
(add Nubra valley here)
Day Nine (19th June)@Leh - Leh – Karu(45kms,1 hour)
Karu - Shakti - Chang La (35kms/steepest climb)
Chang La - Tanksey (55kms) - have lunch here
Night stay @Tanksey
Day Ten - 20th June
Tanksey - Pangong (30kms) and back to Tanksey
Night stay @Tanksey
I hope you meant Tangtse. But I'd rather stay at Spangmik or beyond, as the lake view camping/ homestay opportunity is always more exciting.
Day Eleven - 21st June
TRIP BACK HOME
Now when I am back at Tanksey, do I have to go back to Leh, and then onto Manali Highway ? What would be the route of returning ? I will have couple/three days to return back.
From Tangtse, go to Karu, take left for Upshi, from Upshi take right for Pang. There are few basic facilities at Pang for stay or you can choose to go till Sarchu for more comfortable options. No need to go back to Leh, do refuel at Karu as next petrol pump is at Tandi(365 Km away).
Also, please let me know if any stretch is not doable by Ciaz ?
If it is automatic transmission, I am not sure. If manual you are good. But its a good idea to get a metal sump guard if not there already.
