Lying in the shadow of snow-capped Mount Hood, Portland is a city that celebrates quirkiness. Seeing someone dressed up as Gandalf on the streets on a normal day is practically… normal. This city is also the cleanest in terms of pollution levels and trash and carbon footprint. It has many plants and the Pioneer Courthouse Square is an example of a “living” room. Walk to the heart of Portland, Powell’s Books, for a bookshop experience like nothing you have ever seen. The best city for walking almost everywhere, you will feel nothing but enjoyment being surrounded by greenery and clean streets.
