Chakpori frames the palace's south and west faces; inside, dim chapels and gilded tomb halls follow the guided route. Foreign visitors need an agency-arranged Tibet Travel Permit, organised tour and guide; permits can stop without notice. Acclimatise in Lhasa before climbing at 3,700 metres. Wear long trousers and covered shoulders, remove hats in chapels and walk clockwise; interior photography, drones, lighters and oxygen canisters are prohibited.
