Often referred to by its full title, Washington State, to distinguish it from Washington, D.C., Washington  offers rugged coastline, mountains, volcanoes, and hundreds of coastal islands to explore. The Cascade Mountains bisect the state, with the damp forested coastal areas to the west, and pineforests, deserts and irrigated farmland of the Columbia River Plateau to the east.
There are many cities in Washington; these are some of the more popular.
Most people in Washington speak English with a Pacific Northwest accent. This accent is considered very similar to general American. Washingtonians generally have little to no problem understanding different accents of the English language.

From British Columbia
Interstate 5 and the Peace Arch  crossing is the main port-of-entry to Washington from Canada, though expect to be in queue for awhile when crossing here. An alternative to crossing at the Peace Arch, is to take the Pacific Crossing  via British Columbia Provencial Route 15, which typicaly has much shorter queues, and is the commercial truck crossing. It continues on as Washington State Route 543, and runs right onto Interstate 5. Both crossings are open 24 hours a day, 7 days a week.
Interstate 5 (and Interstate 205) provide access from the greater Portland area. Interstate 82 / US 395 provides access from eastern Oregon to the tri-cities area of Eastern Washington.

When you visit Seattle, be sure to check out these renowned coffee roasters (in no particular order):
