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.
Rocky Mountains ↗Trailheads sit above 2,400 m; give the first day to the altitude, not to a summit.
Rocky Mountains ↗I-70 west of Denver and other high passes close for snow and for avalanche control; check the state road site the morning you drive.

Wyoming is the least populous US state, so the trip is a driving trip: two national parks in the northwest corner, Devils Tower in the northeast, and long empty highways between. Pick one or two bases and accept 3–6 hour drives rather than trying to see the whole state in a week.

Night sequences

4 nights: Jackson 3 (Grand Teton) + Cody 1 (Yellowstone east side)
7 nights: Jackson 3 + Yellowstone lodges or Cody 2 + Sheridan 1 + Devils Tower 1
10 nights: Add Cheyenne or Laramie 1–2 for the southern I-80 leg

Flying between Wyoming towns usually means a connection in Denver or Salt Lake City and can cost more than the drive; treat the car as the default.
Yellowstone and Grand Teton lodging and campsites inside the parks book out far ahead for summer; reserve before you fix flights.
I-80 across southern Wyoming is fast but bleak — the two-lane byways are the reason to drive here.
