The city of Portland was founded in 1845 and lies on a volcanic field, with one volcano nearby which could one day become active again. With a river splitting the city right down the middle as well, this is one of the most geographically interesting cities in the United States.
Though this city does not get much extreme weather, it tends to be rather dry in the summer and wet in the winter months. Other than that, it is pleasant environment with mildly warm summers and mildly cold winters.
The extent of outdoor adventure in the city lies with state parks. Visitors as well as locals can get out in the wild and go hiking or bird watching in these parks, though they are not the most spectacular to see in the country.
There are also a wide variety of museums and historical features throughout the city, which should appease most visitors who are interested in history for a little while.
Other than that, there are no real major attractions to the city of Portland. Visitors mainly enjoy the same amusements that entertain the local population all year round, such as the local zoo and a variety of restaurants and hotels.
