Unquestionably, your best way to explore the region is by car, although most of Ashland's key attractions, hotels, and dining are downtown and within walking distance of one another. Interstate 5 runs north–south the length of the Umpqua and Rogue river valleys, linking Roseburg, Grants Pass, Medford, and Ashland. Many regional attractions lie not too far east or west of Interstate 5. Jacksonville is a short drive due west from Medford. Highway 138 winds scenically along the Umpqua River east of Roseburg to the less-visited northern end of Crater Lake National Park. Highway 140 leads from Medford east to Klamath Falls, which you can reach from Bend via U.S. 97.
