This had slipped my attention until I read about it on George Hamlin’s excellent Observation Deck blog, but it turns out Helsinki Vantaa Airport in Finland has opened a new viewing area for spotters to watch aircraft movements.
The ‘Scenic Terrace’ actually replaces the older terrace which had closed down. It reopened in April 2013 and sits atop a building next to Terminal 2, giving elevated views over the aircraft parking ramps and of the two main runways.
The terrace is open from 7am to 10pm daily, but make sure you wrap up warm in the winter months! It is free to enter, and there are vending machines for snacks.
