About Seattle
Seattle sits on an isthmus between Puget Sound and Lake Washington, with the Olympic Mountains to the west and the Cascades to the east. It's a city that outsizes its reputation — world-class food markets, a thriving music scene, and day-trip access to some of the most dramatic nature in the continental US. The rain is overstated; summers are genuinely spectacular.
