July is called as monsoon month of Leh. There won’t be any snow seen around. It is an ideal time to camp. Any route to Leh is safe, provided to do a weather check on the day you start your ride..
Remember Very less chances of Seeing snow, and in the 15 days of July this entire region (jammu to leh) faces maximum temperatures. i visited in the last 15 days of july last year and had to face this heat on our roadtrip . safety wise its quite good to travel during this time. if you can travel in first 15 days of july it would be better.
