Entre-os-Rios Airstrip

The primary reason for the closure was economic and land redevelopment. The valuable riverfront property was repurposed for a major tourism project. The land once occupied by the airstrip was used to construct the Marina de Entre-os-Rios and the large Douro Royal Valley Hotel & Spa complex.

The site has been completely redeveloped and is unrecognizable as a former airfield. The land is now occupied by the Marina de Entre-os-Rios, which provides docking for recreational boats, and the Douro Royal Valley Hotel & Spa, a major resort in the region. There are no remaining traces of the runway or any aviation facilities.

Entre-os-Rios Airstrip was a small general aviation aerodrome. Its primary function was to serve as the base for the local flying club, 'Clube Aéreo de Entre-os-Rios'. It handled light aircraft for recreational flying, flight training, and private use. Its scenic location on the banks of the Douro River made it a notable landmark for local pilots, but it had no commercial or military significance.

Non-existent. The land has been permanently and completely repurposed for a high-value commercial and tourism development. There are no plans, discussions, or physical possibilities for the airstrip to be reopened at its original location.
