1. Be sure to take a sunscreen with you. Going to a beach or just walking without a hat is not recommended. Even in cloudy weather it is likely to get the severe sunburn.
2. While walking through the parks and nature reserves it's necessary to listen to the guide. Don't touch unknown plants in any case. Personal belongings should be closely monitored, as nature reserves are inhabited by quite a lot of monkeys. They can deftly snatch the bag or camera, and it will be very difficult to return your stuff.
3. Markets and shops accept only local currency, any other is simply forbidden. It's better to change money in banks that serve visitors from Monday to Friday, from 8:00 - 9:00 am to 4:00 - 5:00 pm.
4. Tourists have to go shopping with plenty of notes with small face value. In no way you have to pay with large denominations on markets and in small private shops, as it is likely to receive the change with counterfeit notes. If you try to repay them later in a large store or restaurant, then such action would be considered a serious offense.
6. Tap water shouldn't be used for drinking and cooking. It is better to purchase bottled water in stores; in restaurants and cafes it isn’t recommended to order drinks with ice.
7. Main voltage is 220 V; in almost all hotels necessary electrical adapters and connectors are available on request.

9. In public places you need to be quiet, and not to raise your voice when speaking in any case, as such behavior is considered a sign of bad manners. Upon entering the restaurant, the shop or the bank you need to greet and to smile - these are rules of the local etiquette.
