Hello everyone. I'm planning to some places that have hang gliding because my favourite part about traveling is i'm able to overview the whole area while the air blows on my face. Can anyone recommend me some place with that activity ? Many thanks

Lonely Planet guide books usually cover that, so you might go to your local library and check the index. And if it's aerial views that appeal, rather than hanggliding in particular, you might also look for paragliding, hot air balloon rides, and parasailing. Good luck!

Queenstown, New Zealand offers hang gliding.

A number of years ago we spent some time in Interlaken, Switzerland. In the morning, we went up one of the Alps for lunch and sat on the mountainside watching hang gliders going off the Alp and later on that afternoon, sat on a hotel porch in town watching them land on the park across the street. Wonderful day. You should check it out!

We saw a lot of hang gliders during our visit to the Berner Oberland. We were in Murren for the day and enjoyed all the colorful gliders making their way down to the valley below.

Most of the air sport enthusiasts I saw in the Bernese Oberland were paragliders, not hang gliders, but if the OP is interested in paragliding, yes, that's a major destination for it and I can happily recommend paragliding-jungfrau
Tandem flights in Lauterbrunnen - Paragliding Jungfrau

Can you be more specific about where you are traveling?
I'd recommend Torrey Pines Glider Park in La Jolla, CA near San Diego, You take off in the glider off a cliff and soar over the Pacific Ocean.
