When visiting Iceland, it is important to remember that tipping is not customary in restaurants or bars, as service charges are usually included in the bill. Additionally, it is considered polite to remove your shoes when entering someone's home. While casual clothing is generally acceptable, it's recommended to dress warmly and in layers due to Iceland's unpredictable weather. Embrace the local custom of bathing in geothermal pools but make sure to shower before entering. Be mindful of preserving the environment by not disturbing wildlife or straying off designated paths. Overall, Icelanders appreciate modest and respectful behaviour from visitors.
