With a population of only 26,000, SeaTac is a small city located between nearby Seattle and Tacoma, from which the place gets its name from a combination of both cities. It lies in the south of King County in Washington State, as a suburb of Seattle on the west coast of America. Sea-Tac International Airport dominates the city, which stands within its boundaries, although small surrounding communities also contribute to its population.

The most dominant attraction of SeaTac is its airport, known as the gateway to the Pacific Northwest, which occupies a large, open and innovatively designed building with connections to cities worldwide. In addition to the airport, parks make up the city of SeaTac, seven in total including Angel Lake Park, Bow Lake Park and Grandview Park, in which visitors can walk, cycle, fish, picnic, play sport, explore the playgrounds, or even swim. SeaTac has small landmarks of local history, including two Native American canoes estimated to be 300 years old, found at the bottom of a local lake, and an old, mid-19th Century military fort road. The city is also full of natural beauty, most abundantly found in the Highline Botanical Garden, which hosts a range of rare and diverse plant life within its landscaped garden space.

The city is exceptionally accessible for international visitors as the SeaTac airport is its most dominant feature, which also has excellent transport links to other places in Washington State, including Seattle. Drivers can reach SeaTac via any of three major highways, including the Airport Expressway, or visitors can use the public transport services of Link Light Rail, King County Metro and Sound Transit Express.

The history of SeaTac began in February 1990, when the local government incorporated and founded the city. Over the years, the city expanded and improved its services, including investing in the parks and entertainment and creating a central city hall.
