Visit the Northwest.
Whether you want to wrap yourself in flannel to hit the muddy banks of Wishkah River or wish to explore Idaho from the banks of the Boise River, there’s something for every kind of explorer in the Northwest region. Cultural landmarks and thriving modern scenes abound in Portland and Seattle, but there’s so much more to the region than these two show-stealing metropolises. See everywhere Southwest can take you in the Northwest and start planning your next getaway near the Pacific.
