- 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.
- Great Plains ↗A car is effectively required outside the big cities; rural roads can be in poor condition.
- Great Plains ↗Tornado season runs spring to summer; outdoor sirens warn people outside, and severe-weather radios are the indoor warning.
South Dakota splits at the Missouri River. Almost everything you came for — Mount Rushmore, Custer State Park, Badlands, Wind Cave, Deadwood — sits west of it, spread across the Black Hills and the plains east of them. Rapid City is the practical base: airport, car rental, cheapest beds. From there, Mount Rushmore is a short drive, Custer State Park and Deadwood are longer, and the Badlands are a separate full-day loop east on I-90. Fly into Rapid City (RAP), rent a car, and give the west 3–4 nights.
