Skydiving is exactly as mad as it sounds and somehow better. You leave the aircraft, fall through the sky for the better part of a minute, then the canopy opens, the noise stops, and you float down with a view nobody else gets. The freefall is the bit that rewires your brain.
Most first-timers go tandem, strapped to an experienced instructor who handles everything, so there is almost nothing to learn beforehand. If you catch the bug, you can train towards solo jumps from there.
The operators on adventuro run tandem jumps and training with experienced instructors and rigorously checked kit. The hardest part is the shuffle to the door. After that, gravity does the work.
