Remember to return the gesture if someone offers you a wai.

  • Dress Modestly: While beachwear is acceptable on the beaches, it’s essential to dress conservatively when venturing into towns or visiting sacred sites. For both men and women, covering the shoulders and knees is recommended, especially when visiting temples. Carrying a sarong or a light scarf can be handy for such occasions.

Shopping and Bargaining:

  • Haggling: Bargaining is an integral part of shopping in local markets. However, it’s essential to do so with a smile and in a friendly manner. Start by offering a price lower than what you’re willing to pay and meet the seller halfway. Remember, the goal is to reach a price that’s fair for both parties.

  • Support Local Artisans: Consider buying handcrafted souvenirs from local artisans. Not only do you get a unique keepsake, but you also support the local economy and craftsmanship.

Health and Safety:
