Portland is the largest city in Oregon and accordingly one of the state's best vacation destinations. Also known as the City of Roses, this city along the Willamette River wows visitors with its diverse street food, quirky counterculture, and sprawling bookstores such as the world-famous Powell's Books.
Portland is the 5th best city in the United States for outdoor activities, thanks in part to open-air grounds like the expansive Forest Park.

Or, kick back at one of the many breweries in the #3 best city for craft beer in the United States. Unique locations like McMenamin's brewpubs in renovated cinemas or historic hotels do their part to "keep Portland weird."
