AI-Enhanced Insights

Southwest Washington Regional Airport is a medium-sized general aviation facility serving the Kelso-Longview metropolitan area in southwestern Washington state. Located near the confluence of the Cowlitz and Columbia Rivers, the airport provides convenient access to the scenic Pacific Northwest region, including Mount St. Helens and the Cascade Range. It primarily supports general aviation, corporate aircraft, flight training, and recreational flying rather than scheduled commercial service.

💡 Local Tip
If you're flying in during clear weather, request a flyover of Mount St. Helens on your approach—the volcanic peak is just to the east and offers one of the most dramatic aerial views in the Pacific Northwest.
🚖 Getting There

Renting a car is the most practical option for travelers, as there is no public transit directly serving the airport and ride-sharing availability can be limited. The airport is easily reached from I-5, with quick connections to both Kelso and Longview via local roads. Visitors traveling from Portland International Airport (PDX) can reach the field in roughly 90 minutes by car.
