What's your citizenship? How long a vacation are you planning? Visits are limited to a maximum of 180 days out of any 365-day period, but upon entry, immigration officers determine your maximum stay, not to exceed 180 days. You should be prepared to prove you have sufficient funds for all typical tourist expenses for the duration of your stay - round-trip tickets, hotels, restaurant meals, sightseeing, local/ground transportation, etc.

IF you are a citizen of a visa waiver country, you must obtain eta prior to boarding your flight. If you are not from a visa waiver country, you need to apply for a proper tourist visa.

It depends what country your are a citizen of. Getting a passport is the first step.
