Snoqualmie Pass is a small community in Kittitas County, Washington, United States. It is known as a census-designated place (CDP). This means it's an area identified by the U.S. Census Bureau for statistics. The community also includes the area called Hyak. In 2020, about 372 people lived here.

The community gets its name from the mountain pass it sits on. This pass is where Interstate 90 crosses the Cascade Range mountains. The pass itself is named after the Snoqualmie tribe. They are a Native American tribe who originally lived in the Snoqualmie Valley, which is west of the pass. The part of the mountain pass in King County, to the west, is not part of this community.

Snoqualmie Pass is a wealthy area. It ranks very high for income per person in Washington state.

Fun Things to Do in Snoqualmie Pass

Snoqualmie Pass is a popular spot for outdoor fun. Many of the homes here are mountain chalets and condos. People from the Seattle metropolitan area often use them for vacations. About 300 people live here all year. While winter sports are the biggest draw, you can find outdoor activities all year long.

Hiking and Trails

The famous Pacific Crest Trail goes right through Snoqualmie Pass. There are many other trails for hiking and climbing in the summer. In winter, these trails are great for cross-country skiing and snowshoeing.

Skiing and Snow Sports

Snoqualmie Pass is home to the Summit at Snoqualmie. This is a group of alpine ski areas run by Boyne USA Resorts. The Summit has four main ski areas:

  • Alpental
  • Summit West (used to be Snoqualmie Summit)
  • Summit Central (used to be Ski Acres)
  • Summit East (used to be Hyak)

The Summit at Snoqualmie is the closest ski area to Seattle. This means it can get very busy on weekends!

Iron Horse State Park in Hyak offers more winter fun. You can find groomed trails for cross-country skiing, sledding, and snowshoeing there. In the summer, the park's gravel railroad bed is perfect for hiking and bicycling.

Other Outdoor Adventures

Snowmobiling is also very popular just east of the pass during winter. In the summer and fall, you might see paragliders and hang gliders flying high above the valley. They often land near Lake Keechelus.
