Columbia Gorge Regional Airport — Dallesport / The Dalles, United States

Columbia Gorge Regional Airport, coded DLS, straddles the border between Dallesport, Washington, and The Dalles, Oregon, along the Columbia River Gorge. This general aviation airport primarily serves private pilots, agricultural operations, and recreational flying rather than scheduled commercial airline service. The Columbia Gorge area is known for wind sports, orchards, and dramatic river scenery, and DLS supports related charter and personal aviation activity for both Washington and Oregon communities on either side of the river. Its dual-state location reflects the geography of the gorge itself, which forms a natural boundary. Nearby larger airports in Portland handle the region's major commercial air traffic, leaving DLS to smaller-scale regional needs.
