- 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.
- South ↗A car is close to essential outside city cores; interstate driving is the cheapest way to cover ground.
- South ↗Tipping is expected: 18–22% at sit-down restaurants, US$1–2 a drink.
- Louisiana ↗Legal drinking age is 21 statewide; enforcement is looser in New Orleans and parts of Acadiana, stricter in north Louisiana.
- Louisiana ↗Louisiana requires clearing the intersection before the light turns red; stop at yellow if it is safe to do so.
- Louisiana ↗Interstate 49 runs at 75 mph (120 km/h) outside Alexandria — the only 75 mph limit in the state, and strictly enforced.
- Acadiana ↗A car is effectively required: sights, dance halls and swamp tours sit outside town, with no useful rail or bus network.
- Acadiana ↗Louisiana allows drive-through daiquiri sales but has an open-container law — do not drink in the car; wait until you arrive.

Finding the local time zone…
Times are local to the spot (zone loading). The half-hour margin is our rule of thumb, not an official figure; light fades earlier in forest or under cloud. Carry a headlamp on any route that could run late.

- Visitor centre parking is paved and wheelchair‑accessible.
- Boardwalk sections are level but may be uneven; limited wheelchair routes.
Visiting lightly
- Stay on designated trails to protect fragile cypress roots.
- Use refillable water bottles; refill at visitor centre.
- Support local guides who follow low‑impact practices.
