Oregon is full of unique and exciting places to visit, ranging from natural volcanic sights to beaches along the Pacific Ocean to a scattering of vineyards. Portland, the state's most populous city, may be one of America's best kept secrets, offering a range of attractions, inlcuding museums, parks and professional sports teams. Near to Portland and bordering Washington, visitors will find the Columbia Gorge-Mount Hood region, which boasts the second largest waterfall in the United States, Multnomah Falls. Explore Oregon's 400 mi (640 km) of Pacific coastline or tour the Willamette Valley, home to Eugene and the state's capital city, Salem.
