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.

Southwest Washington is the north bank of the Columbia: a gorge, a volcano, and a wide Pacific beach, all within about three hours of each other on I-5 and US-101. Portland's airport sits across the river, so this region is easier to reach than its small towns suggest. Sleep in Vancouver for the gorge and Mount St Helens, in Longview or Kelso for the coast road, and in Long Beach or Ilwaco for the beach itself. A car is close to essential outside Vancouver.

Plan the nights

How to split the nights, day-trips and what to do with your bags

Open Plan the nightsClose Plan the nights3 partsNights · Day-trips · Bags

Night sequences

2 nights: Vancouver 2: Fort Vancouver, gorge day, Mount St Helens visitor centres
3 nights: Vancouver 2 + Long Beach or Ilwaco 1 (long driving day between)
4 nights: Vancouver 2 + Long Beach 2, coast via WA-4 or US-101

Vancouver + gorge + Mount St Helens + Long Beach in two days is mostly windshield time.
Coast weather is wetter and cooler than Portland; pack a shell even in summer.
Mount St Helens roads and Johnston Ridge close seasonally — check before committing a day.

Regional passes

Verdict first

Washington State Discover Pass

check

Covers day use at many state parks (Cape Disappointment, Beacon Rock); pays only if you visit several in a year.

Amtrak Cascades

check

Useful for Centralia, Kelso and Vancouver without a car; no service to the coast.

County transit day passes

skip

Cheap but weekday-only and sparse; not a substitute for a car on a short trip.
