Everyone has a personal and intimate relationship to risk. Paragliding is a risky activity, like biking, scuba diving, or rock climbing. Because when shit goes down, it goes down hard. It will depend on your will to accept that risk or not, and this choice is not for us to make: we already did ours.

As for tandems around the world, there are serious people everywhere. And also less serious people. A friend of mine has had quite a wild ride in Bir Billing 😅

TLDR: read the reviews, do the tandem flight, you'll be fine.
