Hey Raspreet, Ladakh will be great in July. You can plan your itinerary starting from Delhi. You can take a bus to Manali and start your journey from there. Check before you leave, about the Manali - Leh Bus service. Keylong will be your first stop and it is one of the most beautiful places to stay if you are looking for peace. The road to Leh will be an experience in itself. Try to stay in Leh for at least for acclimatization, before heading to any high altitude places. Keep 6 7 days to explore Ladakh, places like Nubra Valley, Pangong Tso, and even Leh needs a good amount of time.
