Absolutely, here’s a simple guide about cultural etiquette in Sri Lanka and whilst Sri Lanka is not a strict country, politeness and etiquette should be strongly considered:

Cover shoulders and knees in temples and mosques – modest dress is always recommended in areas of worship
Please don’t turn your back to Buddha
Avoid touching or sitting on statues
Take shoes off when entering a home and following guidance at temples
There’s no need to raise your voice in Sri Lanka, be quiet and respectful
Avoid touching people’s heads
Sri Lankan’s traditionally eat with their right hand
Swimwear is for the beach and pool only and being shirtless isn’t appropriate away from the beach or pool either
Please don’t give out money if requested, and avoid just handing out sweets or pens to children – let us know if you would like to get involved or donate to a legitimate NGO
There’s no need for over the top physical displays of affection
