Snohomish County has one official airport and several municipal airports. The county also is connected by two ferry lines operated by Washington State Ferries.

The one official airport is Paine Field, otherwise known as Snohomish County Airport. There are smaller outlying airports, such as Harvey Field in Snohomish. There are two municipal airports, Arlington Municipal and Darrington Municipal. There are also two private airports, one in Lake Stevens and another in Granite Falls.

As said in the introduction above, there are two ferry routes operated by Washington State Ferries in Snohomish County waters that go to and from different counties from the county.[5] The first line is the Edmonds-Kingston route, which carries SR 104. SR 104 terminates in the west at US 101 west of the Kitsap Peninsula, after crossing the Hood Canal over the Hood Canal Bridge. SR 104 terminates in the east at Interstate 5 on the county boundary with King County.[6] The second line is the Mukilteo-Clinton line, which carries SR 525. SR 525 terminates in the west at SR 20 on Whidbey Island, near where SR 20 goes across on another ferry line to US 101. SR 525 terminates in the east at an interchange with Interstate 5, where it continues as Interstate 405.[7]


Snohomish County is one of the most-populous counties in the United States without a four-year, baccalaureate degree-granting institution.[8]
