Greetings and Courtesy: The traditional greeting is 'Namaste' or 'Namaskar', placing the palms of the hands together in front of the chest and slightly bowing the head. It is a gesture of deep respect. Always use your right hand to give or receive things.

Visas and Trekking Permits: Most nationalities require a visa to enter Nepal, which can be obtained on arrival at Kathmandu airport. To trek, you will need specific permits such as the TIMS (Trekkers' Information Management System) card and the permit from the corresponding national park or conservation area.

Health and Altitude Sickness: Always drink bottled or purified water. If you are going trekking, it is crucial to find out about altitude sickness (soroche). The key is to ascend slowly, stay well hydrated, and listen to your body. Don't underestimate the symptoms.

Respect in Sacred Places: Dress modestly when visiting temples and monasteries, covering shoulders and knees. Always take off your shoes before entering. Always walk around the stupas and temples in a clockwise (circumambulation) direction.
