That was a really fun thing to do 🙂 You can do it alone or two people together (I think even three, but not 100% sure) 🙂 What happens is that you’re going out into the sea on a boat, getting attached to a parachute, and, as the boat speeds up, fly into the air! Then you can enjoy sightseeing from the air! It wasn’t at all scary, even with my fear of heights, I don’t know know why:) It’s really quiet and relaxing up there. And Barcelona (here is an example of the tour, by the way) looks awesome from above…
P.S. The camera I use for all of my adventure videos is Insta 360 One X (not an add, unfortunately 🙂 , I just love it and here’s my experience with it 🙂 )
As they pull you back, they purposefully make you dip into the water a bit, so I totally advise you to wear a swimsuit 🙂 Unlike me; I was on my way to the airport doing that, and fully dressed 🙂 Had to buy new dry shorts on my way after 😀
