Bhutan Travel Tips

Be respectful for religious sites and beliefs. Do not use fingers to point, especially at deities or religious objects
A formal greeting is to bow with hands open and outstretched and the palms up.
In Bhutan, tight-fitting or sexy clothes are not suggested to wear. You should wear solemnly and take off the shoes and hats before visiting monasteries or other religious sites. 
Most Bhutanese love to be shown the photo on the screen, but you should ask them first before taking picture.
Never point your feet at someone. If you are sitting on the floor, cross your legs or kneel so that your feet are pointed behind you. Do not touch the crown of the head.
The exchange of presents is an important part of Bhutanese life. When receiving a present from someone, you are expected to reciprocate by giving a present in return.
A phallus is an erect penis referred to as the "Mad Saint" or the "Divine Madman". You should NOT be alarmed when you see this image on a person's home.  

Water used for drinking, brushing teeth or making ice should have first been boiled or otherwise sterilised. Mineral water is widely available. Milk should be boiled. Powdered or tinned milk is available. Only eat well-cooked meat and fish. Vegetables should be cooked and fruit peeled.
There are no private health clinics or physicians in Bhutan, but all district headquarters towns have a hospital, and will accept travellers in need of medical attention. Treatment is free, even for tourists. In most large towns there are shops that sell medicines. Many of these are available without a prescription in these medicine shops.
