Entry and health

Health information

"No specific vaccinations are required for Hawaii, but routine vaccines (MMR, DTaP, polio, flu) are recommended. The sun is intense year-round; use reef-safe sunscreen, wear a hat, and stay hydrated, especially during hikes. Tap water is safe to drink. Medical facilities are excellent in Honolulu, with urgent care clinics and hospitals nearby. Travel insurance is advised for medical emergencies."

Culture

Local customs

"Hawaii has a strong aloha spirit: greet with 'Aloha', be respectful, and remove shoes when entering homes. Dress is casual—shorts, t-shirts, and sandals are fine, but cover-ups are appreciated at temples or formal events. Tipping is customary (15-20% at restaurants). Avoid taking lava rocks or sand as souvenirs; it's considered bad luck and disrespectful."
