- North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
- North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
- North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
- United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
- United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
- United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
- United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.
St. Louis County is the suburban half of the St. Louis area: 1877 boundaries, about a million residents, and far fewer sights than the city next door. It holds the airport, the big malls, the county seat at Clayton, and a run of parks along the Meramec River. Two nights works if you have a car and want the museums, the Loop and the green belt; without a car, stay in the city and day-trip out on MetroLink.

Arrive & move
Airports are listed under At a glance; this is how to move once you are in
Getting around
You need a car. County buses are slow, sparse and infrequent, so plan on driving unless your day sits on the MetroLink line — the Delmar Loop, downtown Clayton and the Galleria are the useful stops. MetroLink is fast and frequent between the airport, Clayton and the city. A 2-hour MetroLink transfer ticket from the airport costs $4.

Day-trips, door to door
Day-trips

goDoor to door: About 30–45 min

goDoor to door: About 45 min
I-70 northwest by car, about 30 min from the airport

Eat & sleep
Which area to sleep in
Where to sleep
Areas, not hotels: pick the one that fits your arrival time and plans.
Clayton
County seat and business district; hotels, coffeehouses and upscale dining, walkable core, MetroLink nearby. Best all-round base.
Delmar Loop / University City
Storefronts, music venues, bookstores and restaurants on one street; MetroLink stops at the Loop. Best for food and evenings.
West County (Frontenac, Ladue, Chesterfield)
Two upscale malls and highway access; needs a car for everything.
Kirkwood
Small-town downtown with shops and an Amtrak station; good for families and the Museum of Transportation.
