Omaha was originally founded in 1854 and became an official part of the state of Nebraska a few years later in 1857. The climate in this state is rather ordinary with hot, humid summer months followed by colder winter months. Since it is not located near any mountain ranges or large bodies of water, it tends to be more of a culture and art based community as far as attractions to the outside world.
In the Old Market section of town, visitors can walk on old style cobbled streets and explore buildings that have been preserved from historical times. The city has actually extended a great amount of its resources to preserving a good bit of the historical elements of its landscape.
There are also a wide variety of museums throughout the city, making it rich for exploration by those who enjoy history, art, and other cultural artifacts. These museums are accompanied by a variety of shops and restaurants for visitors to stop into as well.
There really are not a lot of outdoor adventures to be gained from this city, mainly due to its central U.S. location that prevents access to waterways or mountain ranges. Since those are the landscape features around which most state parks are centered, there isn't much to do outdoors in this city.
