Hi!
Awesome thing to do buddy!!!
Ladhak is beautiful,
I have made a Bike trip there last summer with couple of other friends,
Shoot what you want to know!!!
Take 1 or 2 Max strip of Diamox along with you, to overcome AMS
Take it atleast 6-8 hours before you start climbing the hills,
Personally I feel people on the heavier side feel it a lot more,
While climbing up avoid having starch based stuff espicially artificial stuff like Maggi/Knor Soup which is easily avaiable up there,
You will find locals having Tents set up approx every 4-8 Hours (100-200 KM),
If you are goin there on Bikes, Please make sure you know how to repair punchers and carry puncher repair kits or extra tubes along with you, Cos for 100-200 KM at a strech you will not find any one to repair Punchers or tend to any Bike problems,
Avoid carrying to much cash with you, there are 2 ATM in Ladhak you can withdraw money from there (J&K/SBI) Let me warn you that it will be pretty crowded and the best time to withdraw is after 10 PM or early in the morning,
Enjoy your ride you will love it, You will find fellow travellers everywhere who will be more than willing to help you out if you happened to run into any trouble,
Places to stay: Single Large Tents/ 50-100 per person or Suite Tent 1500-2500 per 5 persons you can take anyone, Plus you will come across Small Lodge who will rent out rooms at nominal cost 500-1000 Max,
NOTE: Keep tabs of your belongings, People are very friendly there, this lets your guard down and thats when you make a mistake, Personal Exprience!!
PS: Dont miss Visiting Pangong Lake, Monestry, Zang Zang River Rafting in Ladhak, Nubra Valley, Kardungla- The Higest Motorable Road in the WORLD,
You can make a over night stay in Pangong, Its the most beautiful part of Ladhak,
& YES THE FOOD IN LADHAK is awesome, check it out you will love it,
Anything else you want to know let me know...
