Yeah Ladakh is open for tourists are reaching by air and road. It opens almost all the day. But RT-PCR test report is required is mandatory(not older than 96 hrs.)
As aug lies in monsoon period , exploring waterfalls and hillstation would be a great choice.
If you are from Mumbai/Maharashtra , visit places like Mahabaleshwar, Lonavala, Matheran. You will thank me later.
