The majority of Laotians are Buddhists and it is particularly advisable to dressmodestly in Luang Prabang, one of Southeast Asia's most spiritual destinations. If entering a temple, you will be expected to leave your shoes outside and have shoulders and knees covered. It is also forbidden to point your feet towards a Buddha image and women cannot touch a monk. There are many sacred sites and artifacts throughout Laos, please do not enter or touch these without permission. In Laos your head is consider 'high' and your feet 'low', it is generally considered rude to use your feet for anything other than walking and sport. Please respect Lao culture by removing footwear before entering a private home and avoid touching a person's head, as this is extremely impolite.
Please take the normal environmentally friendly steps you should take anywhere in the world, but especially in the third world - use water and electricity supplies carefully, re-use towels in hotels, try to use recyclable goods such as water carriers rather than plastic bottles, protect Laos' wildlife by refusing to buy wildlife products, etc. Try to set an example to Laos' impressionable youth by taking litter away for disposal and not dropping it in the street. Laos loses a little bit of its heritage every time an antique is taken out of the country, avoid buying antique Buddha images and other sacred items, instead try to support local craftsmen by purchasing new, quality handicrafts. Please try not to distribute gifts to children as it encourages begging; instead try to give to an established organization, or village elders.
