No, helicopters are not permitted to fly inside Tibet on the Kailash tour from Simikot route. However, Mt. Kailash Helicopter tour is possible for those travelers with restricted time, yet wants to pay divine attention to Lord Shiva’s abode. For this, you will first fly on a regular flight from Kathmandu to Nepalgunj, and then fly to Simikot from where you will board on a helicopter that will drop you at the Tibetan borderland of Hilsa. From Hilsa, you will take an overland ride towards the shore of Lake Mansarovar.
