Seattle is the largest city in the US Pacific Northwest, set between Puget Sound and Lake Washington with snowcapped Mount Rainier on the horizon. It is known for its coffee culture, tech scene, and lush, green surroundings. Between a legendary public market, ferries gliding across the sound, and mountains in every direction, there is always something worth wandering out to find!

When to go

Summer, from July to September, is the driest and sunniest season and the best time to visit. The rest of the year is famously grey and drizzly, though rarely bitterly cold.

Good to know before you go

The currency is the US dollar and tipping is customary in restaurants and for services. Seattle has a genuinely useful light rail line linking the airport to downtown, plus buses and scenic ferries, so you can skip a car entirely; for door-to-door trips, Uber and Lyft are cheap and everywhere. The hills are steep, downtown traffic is heavy, and parking is pricey, so a rental only makes sense for day trips further out, where a young-driver surcharge may apply under 25. English is standard and rain gear is wise most of the year.

Entry requirements and health

No visa needed

Good news: with a Canadian passport you can just show up for a short tourist stay, no visa needed. Keep an eye on how long you're allowed to stay so your trip fits.

General orientation for a Canadian passport on a short tourist trip, not legal or medical advice. Confirm with official sources, and see a travel health clinic four to six weeks before departure.
