Ontario: 72 miles SE of Baker City, 63 miles NW of Boise, 130 miles NE of Burns
Ontario, the easternmost town in Oregon, lies in the Four Rivers region, at the confluence of the Owyhee, Snake, Malheur, and Payette rivers. Irrigated by waters from the massive Owyhee Reservoir, these wide, flat valleys are prime agricultural lands that produce onions, sugar beets, and, as in Idaho, plenty of potatoes. This region is also where most of the world's zinnia seeds are grown. During the summer, zinnia fields color the landscape in bold swaths. If you're curious to see the flower fields, head south out of Ontario on Ore. 201.
The biggest attraction in the region is the Four Rivers Cultural Center, which focuses on the various cultures that have made the region what it is today. However, there is also some Oregon Trail history to be seen nearby, and south of Ontario lies one of Oregon's most rugged and remote regions. This corner of the state is a vast untracked high desert, and along the banks of the Owyhee River and Succor Creek, you can see canyons and cliffs that seem far more suited to a Southwestern landscape.
