We recommend the following: - 1 pair of long trousers - 1 light but waterproof jacket (Nothing too thick!) - Simple padlock to lock up your belongings - 1 long sleeved top - 1 electrical converter (to avoid blowing out that hairdryer or beard trimmer) - Shoes that are suitable for hiking - Waterproof shoes if you have them - Shoes that are easily removed. (Upon entering temples and many buildings you will be expected to remove your shoes as a sign of respect. The easier, the better.) - Swimwear - A camera is highly suggested to remember your experience! - Insect repellent - Sunscreen. Lots of sunscreen And of course, the usual: passport, spending money, adventurous curiosity, positive attitude, etc!
