Located just west of The Dalles, OR, the Columbia Gorge Discovery Center is the official interpretive center for the Columbia River Gorge National Scenic Area. This 26,100 square foot exhibit wing holds interpretive displays which describe the tremendous volcanic upheavals and raging floods that created the Gorge, explanations of why ice ages occur, how the mighty Columbia River sculpted the ecology of the region for a unique and spectacular diversity of vegetation and wildlife. Native American cultures are represented along with more recent Euro-American activities.

The Discovery Center, parking, and interpretive trails are fully accessible. The interpretive programs are also designed for visitors of all abilites. The Discovery Center also serves as the trailhead for the fully accessible, 8 foot wide, paved, rolling Riverfront Trail.
