Snoqualmie Pass is located on Interstate 90 with easy access to Spokane in the east and Seattle in the west.
Mountains to Sound Greenway
The corridor of I-90 over Snoqualmie Pass is known as the Mountains To Sound Greenway, and offers many sightseeing and exploration opportunities, only a short distance from Seattle. You can print out and take along a PDF "Geo-Tour" of the MTSG at Mountains to Sound Greenway / I-90 over Snoqualmie Pass (coming soon)
Summit At Snoqualmie
With four alpine base areas summit  ski slopes that vary from beginner to advanced. Nights skiing is also available
Alpental Offers everything from beginner to deadly (quite literally) terrain. The in-bounds area at Alpental contains a several-hundred foot tall cliff that's pretty great to ski off of, but check the landing for plenty of snow first, and do this only if you're an expert skier. Pay attention to, and believe the double black diamond signs. The Alpental backcountry is quite impressive and readily accessible; make sure to obtain a Backcountry Pass from the Ski Patrol (at their Shack atop Chair 2) before exploring. Drive east on Interstate 90 from Seattle, approximately 1 hour. The road is an active interstate highway, and is therefore plowed and sanded all winter long, but snow tires or chains may be required.
