Paramotoring takes the simple joy of a paraglider and bolts on a motor and propeller worn like a backpack. That means no hill needed: you run a few steps across a flat field, the wing lifts, and you climb away under power, free to fly wherever the sky allows. It is one of the cheapest and most flexible ways to become a genuine pilot.
Most people start with a tandem flight or a taster, then train towards flying solo. Learning the wing and the motor takes time and good instruction, but the barrier to entry is lower than almost any other powered flight.
The schools on adventuro run paramotor tasters and training with experienced instructors. Few things beat puttering over the countryside at a couple of hundred feet on a calm evening.
