The 46-year-old actor is currently on location in Pahalgam, a region in the Kashmir Valley, where he is shooting sequences for Yash Chopra's new film, PTI reports.
Writing on Twitter, Khan said: "How beautiful is Kashmir...how lovely the ppl & silences that can only be Nature's voice. Feel blessed to be here in the land of sufis."
The Don 2 star previously shot in Ladakh for Dil Se, while the film marks a return to the region for Yash Chopra after an absence of 30 years. Chopra last shot sequences in the valley in 1976 for Kabhie Kabhie, after which it became a heavily militarised zone.
Describing the natural beauty of the valley, Khan quoted a Persian poet, saying: "Rumi time...'Who could be so lucky? Who comes to a lake for water and sees the reflection of moon.' So apt for Kashmir."
News of Khan's arrival in Pahalgam prompted hundreds of local fans to turn out to try to get a glimpse of the star, but due to tight security measures they were unable to do so.
Shooting for the movie will continue in the Zabarwan hills, Dal Lake and Lal Chowk.
The actor, who had complained of breathing problems amid the high-altitude conditions in Ladakh, reportedly plays an army bomb disposal expert in the film, which is said to take place over a large period of time.
Yash Raj recently announced that the film's title, which has been shrouded in secrecy, will be revealed on the occasion of Yash Chopra's 80th birthday.
The movie, which also stars Katrina Kaif and Anushka Sharma, is scheduled to release on November 13.
