Pros: Good starting and arrival time Cons: Need a much improved departure location from Portland. Waiting on the curbside is not very convenient for passengers. It doesn't appear to be a "Bus Station", just a road side pick up area.

Pros: We had a new bus driver. He did a great job. He told us what to expect and he answered all our questions. He should be recognized during his first week. Tips: Take the bus; it’s easy

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.

Once you've gotten hungry from a long day wandering outside, nearly every block downtown has a plethora of food trucks waiting to tickle your taste buds. 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.”
