Oregon is a Pacific Northwest state of extraordinary natural beauty, spanning rugged coastlines, ancient forests, volcanic peaks, and high desert plateaus. Portland, its largest city, is celebrated for its vibrant food scene, craft beer culture, and independent spirit. From the deep blue waters of Crater Lake to the thundering cascade of Multnomah Falls, Oregon rewards travelers who venture beyond the expected.

Oregon has dramatically different climates depending on location. Western Oregon (Portland, the coast, and the Willamette Valley) is temperate maritime — mild, rainy winters and warm, dry summers. Eastern Oregon (Bend, the high desert, and eastern plateau) has a continental climate with hot summers, cold winters, and low precipitation year-round. The Cascade Range acts as a weather divide: the west side receives 35–100 inches of rain annually while the east side receives just 8–12 inches.
