Hey Jignesh, It's best to experience ladakh by bullet ride. If you prefer solo, you can plan accordingly, but if you like to meet & greet with like minded people, you can go for the group of bullet riders.There are lots of options available in a good budget for a trip of approx 12-15 days. Also do let me know, if you need the contact of any such group.
