If you have never flown a paraglider, the unknown part is not the flying — it is everything that happens before it. Here is the whole sequence, so nothing on the day is a surprise.
Before you leave home
Wear closed shoes with some ankle support. Trainers are fine, light hiking boots are better. Long trousers and a light jacket, because the air at 2,600 metres is a good deal cooler than Nairobi. Sunglasses, sunscreen, and nothing loose around your neck.
At the launch
Your pilot will lay the wing out and walk you through the briefing: how to sit into the harness, where to put your hands, and the running steps at launch. This takes about ten minutes and is worth listening to properly. Then you get clipped in, the pilot runs the pre-flight checks out loud, and you wait for a cycle of good air.
The three things that matter
One: run when told, and keep running. Do not sit down early. The wing needs a couple of steps of forward pressure to fly cleanly off the slope.
Two: look out, not down at your feet. Everything about the flight is better when you are watching the horizon.
Three: say something if you feel odd. Motion sensitivity happens to perfectly ordinary people. Tell your pilot early and they will fly straighter, more level lines. Suffering quietly helps nobody.
Landing
The landing field is large and open. Your pilot will ask you to stand up out of the harness on final approach, and then you take two or three steps as you touch down. That is genuinely all there is to it.
