Family trip to the United States: which region to choose?

With children, choose a single region of the United States: Florida for the theme parks, Southern California to mix parks, beaches and zoos, the national parks of the West for children who like walking, New York for a stay without a car. The country is too vast to combine two of them in two or three weeks without spending your vacation on the road. As for formalities, for a family entering with an ESTA, each child, babies included, must have their own authorization, and the car seat follows the law of the state you are driving through.

Florida with the family: theme parks, rockets and alligators

Orlando concentrates what most children expect from the trip: the four parks of Walt Disney World (Magic Kingdom, EPCOT, Hollywood Studios, Animal Kingdom) and those of Universal, including Epic Universe, opened in 2025. Everything is booked online for a fixed date, well before departure.

Florida does not stop at the rides:

• Kennedy Space Center, an hour’s drive from Orlando, displays the shuttle Atlantis and a 111-meter Saturn V rocket.
• The Everglades can be explored by bike on the flat Shark Valley loop, 15 miles (24 km) among the alligators, or by airboat.

Watch out: Park tickets are the biggest item of a stay in Florida, and a quick meal in a park comes to $15 to $20 per person. Cost this item before you fix the number of park days.

Southern California: parks, beaches and zoos without changing hotel every night

Between Los Angeles and San Diego, the legs are short and the program varied. Disneyland, in Anaheim, is the original park of 1955; Universal Studios Hollywood is visited inside a real working studio. Allow in the region of $100 to $200 per day and per person for these two parks depending on the date, an October 2026 order of magnitude to check again on each park’s website.

The rest weighs less on the budget: Griffith Observatory is free, and Santa Monica Pier has its Ferris wheel and its 1922 carousel. In San Diego, the zoo takes a whole day, the Safari Park in Escondido spreads its savannah over 730 hectares, and the aircraft carrier USS Midway takes 3 to 4 hours.

The climate is mild all year, 68 to 82 °F (20 to 28 °C) in summer. The Pacific water stays cool, 64 to 68 °F (18 to 20 °C) in midsummer, and a morning mist covers the coast in May and June.

The national parks of the West with children: the Junior Ranger program

Zion, Bryce Canyon and the Grand Canyon have short trails alongside the big hikes: the paved Riverside Walk in Zion (3.5 km), the Canyon Overlook (1.6 km), the viewpoints of Bryce. The shuttles in Zion and on the South Rim of the Grand Canyon save you looking for a parking space.

The National Park Service’s Junior Ranger program gives children a goal. The principle, according to nps.gov:

• you ask at the visitor center for an activity booklet, which is free;
• the child fills it in during the visit;
• they take an oath in front of a ranger and receive their badge.

Most of the more than 400 sites in the network offer it, with no age limit.

Non-residents pay more. At the time of writing, in October 2026, 11 parks, including Zion, Bryce Canyon, the Grand Canyon, Yellowstone, Yosemite and the Everglades, add $100 per non-resident visitor aged 16 and over. The annual pass for non-residents, at $250, removes this surcharge. Check again on nps.gov before you leave.

Watch out: At Horseshoe Bend, most of the rim has no guard rail, 980 ft (300 meters) above the Colorado. In Zion, the final ridge of Angels Landing is crossed by holding on to chains. And narrow canyons are exposed to flash floods: never when a storm is forecast.

New York with children: the only stay without a car

New York is done entirely by subway, paid for contactless with a bank card, so with no car seat and no parking. The Museum of Natural History, Central Park, the Statue of Liberty and Coney Island easily fill a week. Two reservations: you quickly walk 9.3 miles (15 km) a day there, and the city is expensive, $15 to $25 at lunchtime and $35 to $60 in the evening per person, with tax and tip on top.

ESTA for minors: one per child, babies included

The US authorities are explicit: children, accompanied or not and whatever their age, must obtain their own ESTA authorization. The passport presented must be an electronic one. The ESTA costs $40.62 per person since October 16, 2026, which makes $162.48 for a family of four. Whether the ESTA applies to you depends on your passport, and the steps to follow are in our ESTA guide.

Car seats in a rental car: the law changes from one state to the next

The rule is not the same in California and in Florida, and Florida law makes the driver of the vehicle responsible. The two texts, noted in October 2026:

• California: rear-facing before the age of 2, unless the child weighs 18 kg or more, or is 40 in (1.02 m) tall or more; a seat or booster in the back before the age of 8; seat belt alone from the age of 8 or from 4 ft 9 in (1.45 m).
• Florida: child seat up to the age of 3, seat or booster at 4 and 5.

Tip: If your route crosses several states, the most cautious course is to follow the strictest rule and keep the booster until 4 ft 9 in (1.45 m): a piece of cautious advice, not a legal obligation. The rest is in renting a car in the United States.

Distances and pace: count the hours of driving, not the kilometers

A few orders of magnitude before you draw up your route:

• Miami to Orlando: 3 hours 30 minutes;
• Miami to Key West: 4 hours without stops, on a road with one lane in each direction;
• Zion to Bryce Canyon: 1 hour 30 minutes;
• North Rim to South Rim of the Grand Canyon: 4 hours 15 minutes, for 9.9 miles (16 km) as the crow flies.

In Los Angeles, traffic is heavy from 7:00 to 10:00 and from 15:00 to 19:00: group your visits by neighborhood. Our itineraries are not written for families, and their pace is an adult one, but they give you the place-by-place detail to build your own, for example Florida in 19 days.

School vacations: which season to go to the United States with the family?

• Summer suits Southern California and the parks of the West, with reservations: more than 104 °F (40 °C) at the bottom of the Grand Canyon and afternoon storms in July and August. In Florida, it is the season of daily storms and of hurricanes, from June to November with a peak in August and September.
• Winter and spring, from December to April, are Florida’s dry season.
• Spring and autumn are the best seasons for New York, which is hot and humid in summer.
• The North Rim of the Grand Canyon only opens from mid-May to mid-October: check its status on nps.gov before you plan it in.

The full calendar is in when to go to the United States, and the spending items are in the budget for a trip to the United States.

So, where to go in the United States with the family?

• Children who dream of theme parks: Florida, preferably between December and April.
• Summer vacation, mixed wishes: Southern California, for example by following our itinerary from Los Angeles to San Diego at your own pace.
• Children who walk: the parks of the West, from May to October, with the Junior Ranger booklet.
• No wish to drive: New York, in spring or autumn.

In every case, one ESTA per child for families traveling on that authorization, and a car seat that complies with the state you are driving through. The other regions of the country are on the United States page.
