It depends on the format.
If the trip is built around long independent downwinders, riders should normally reach an independent level first.
Someone who is still learning water starts or struggling to stay upwind will gain much more from spending time at a suitable training spot before attempting long coastal routes.
That doesn't mean Brazil isn't suitable for beginners. Quite the opposite.
Kitesurfing lessons in Preá can be a much better starting point for riders who are still building their water start, upwind riding and independent kite control before moving on to longer downwinders.
The progression should simply happen in the right order:
control first, distance second.A first proper downwinder becomes much more enjoyable when the rider can focus on the route rather than simply trying to stay on the board.
