well I don't know how it is for Miguel, but for kiteboarding or paraglding you can more or
less just take your car and drive to the dunes or the beach.

People doing these sports are friendly :-)

For Kiteboarding go to Zekreet or Whakra Beach
For Paraglding go to Sealine and drive in to the dunes... you will see the gliders in the air.

There is also instructors for both here in doha... plus the shops that sell the equipment.

Write me a pm and I give you the numbers of the guys.
