The Chehalem Mountains are a mountain range located in the U.S. state of Oregon, primarily in Yamhill County, but extending slightly into Washington County. The range, which reaches an elevation of 1,633 feet at its highest point, stretches over 20 miles in a northwest-southeast direction.
The Chehalem Mountains are part of the larger Northern Oregon Coast Range and are known for being the home of diverse wildlife, including blacktail deer, elk, and several species of birds. The mountains are heavily forested, featuring a mix of Oregon white oak, Douglas fir, bigleaf maple, and Pacific madrone.
The lower and middle elevations of the mountains have a temperate climate, while the higher regions receive heavy rainfall and occasional snowfall. Many of the slopes are steep, leading to the formation of fast-running streams and waterfalls.
The Chehalem Mountains are also well-known for its wine industry. It holds some of Oregon's best vineyards and wineries, producing particularly notable Pinot noir, Pinot gris, and Chardonnay. The unique climate, with cooler temperatures and a higher average rainfall than the surrounding regions, contributes to the distinct terroir of the wines produced here.
In terms of recreational opportunities, the mountains feature hiking and mountain biking trails, bird watching spots, and stunning scenic viewpoints. Chehalem Ridge Natural Area and Bald Peak State Park are two popular locations for outdoor activities within the range.
