Mosier Plateau is a stunning 45-acre public preserve in the Eastern Gorge, located just half a mile from the city center of Mosier, Oregon, and bordered by over a dozen privately owned properties. A haven for wildflower enthusiasts, the plateau boasts over 50 species of native flowers, attracting visitors from around the world to witness its seasonal beauty. In addition to its impressive floral diversity, the property features a small stand of Oregon white oak and ponderosa pine.

The preserve is home to two key habitat types: oak-conifer forests and prairie. Notable plant species include lupine, balsamroot, lomatium, buckwheat, cluster lily, and snowberry. Although no formal wildlife survey has been conducted, sightings of mountain lions, ringneck snakes, black-tailed deer, and various songbirds have been recorded by staff and visitors alike.

Open year-round, Mosier Plateau features a 3.5-mile out-and-back trail that begins in downtown Mosier and leads up to the preserve, offering panoramic views along the way. The plateau is part of the Gorge Towns to Trails initiative, which envisions a 200-mile trail network linking communities and promoting recreational access while encouraging sustainable transportation options throughout the Columbia Gorge.
