Hawaii is a safe travel destination, with relatively few risks facing tourists. When enjoying the nightlife in Honolulu, be sure to stick to well-lit areas and travel in groups whenever possible. Pickpockets are of moderate concern in crowded areas, though you'll find relatively few such places in the Hawaiian archipelago. Hire cars are easy marks for thieves, so it is wise not to leave valuables in the passenger area or boot.

Medical facilities are well-equipped to respond to health emergencies on Oahu, and particularly in Honolulu. When visiting neighbouring islands, you'll find that hospitals are able to respond to most medical situations, though in extreme medical cases a trip to Honolulu may be necessary.

The primary concern for tourists is overexposure to the sun and elements. Stay hydrated and use plenty of sunscreen when visiting the beach and snorkelling, and don't forget to pack an extra layer of clothing when planning excursions to the islands' high-altitude interiors.

As with the rest of the US, those living in Hawaii speak and understand English. Hawaiian is also an official state language, and many locals speak pidgin, a Creole of these two languages, in informal situations.

Hawaii uses the US dollar (USD), with US$1 equal to 100 cents.

Hawaiian customs officials enforce bans on regularly prohibited items such as firearms, ammunition, illegal drugs and explosives. Beyond these items, there is also a strict set of regulations governing the import of live, agricultural products (whether animals or plants). Another set of restrictions govern the export of fruit and produce from Hawaii to the US mainland, and only those items which have been previously inspected will be cleared for shipment to the contiguous US. The following may be brought into the US free of duty: one carton of cigarettes; one litre of spirits; and US$200 worth of merchandise.

Visitors will find mainstream American etiquette relatively informal. Greetings consist of a simple handshake and a smile, and most people prefer to operate on a first-name basis. Americans are known for their directness, and this habit of getting straight to the point is not intended to offend. Locals practice a unique blend of local and mainland culture, and this cultural exchange can be a bit precarious at times. With this in mind, it is best to avoid broaching political topics, particularly as it pertains to Hawaiian sovereignty.

European Union nationals need to fill out a form requesting a visa at least 72 hours before they plan to travel to the US. You may need to show evidence of funds and an onward ticket. Canadians also require a passport to enter the US.
