Given below are relevant customs and regulations:• According to the law of the country, it is illegal to smoke or drink in public. Smoking and consuming alcohol is strictly prohibited at all cultural and religious attractions.• No visitors are allowed to enter religious places under the influence of alcohol.• Selling and serving of alcohol is prohibited on Poya full moon days as these days have a religious significance, according to Buddhism.• Visitors of both genders have to wear decent clothing to cover the body appropriately when visiting religious places and shorts and sleeveless tops are not acceptable. This rule is strictly adhered to at all religious sites especially the Sacred Bo Tree and Stupas in Anuradhapura and the Temple of the Tooth in Kandy.• Visitors should remover hats, caps, shoes and slippers when entering buildings and sites with religious monuments. Most of these places have a secure facility at the entrance for visitors to leave behind shoes and slippers for a very small fee.• At some attractions such as Dambulla and Kandy, visitors have to purchase a camera permit for their still photo and video cameras.• No one is allowed to take photographs with Buddha Statues facing the back to the statue.
