Yes. Shinta Mani Mustang requires a minimum of 5 consecutive nights, this is a firm policy set by the hotel and cannot be split around Upper Mustang excursions. Himalayan Glacier builds this into every itinerary as Days 5–9, combining it with 3 nights at Dwarika’s and 2 nights at The Pavilions for the 11-day journey. Guests wishing to also see Upper Mustang (Kagbeni, Lo Manthang) add a 3-night extension requiring the Restricted Area Permit at USD $500 per person, arranged by HG Kathmandu.
