Hi Shree, The best time to visit Ladakh is May till October. It's not advisable at all, As in October Leh closes due to heavy snowfalls especially by road. Attached with my comments you can check curated trips by fellow travelers. Please take a look. Thanks!
Hi, Shree, they start blocking the roads by the last week of the september usually. However Leh is accessible and there are travellers generally for intense snow Trekking and winter games mostly. Happy Travelling . Regards.
The interior Roads are mostly never blocked in Ladakh and even if there's snowfall Army clears them within a day or max two days. The roads from Manali and Srinagar are closed We visited ladakh in late December and never had a problem anywhere. Khardung-La and Pangong both are open and we were the only ones at that time. Imagine the entire Frozen Pangong and just you :) Do check our trip pictures https://www.tripoto.com/trip/ladakh-in-winters-yeah-sure-5c50198f38245
