To find out a new paragliding site, you need a few points Should consider because It's dangerous if possible Avoid adventuring by yourself on a new place if possible check that other pilots have flown there before.  If you want to do this then You must have a lot of flying experience to do this.

This depends on your level. If you have already done paragliding before, you should know by now how paragliding site looks like. If you haven’t done before, I assume that you will not try to learn it by yourself.
A Good Paragliding Site should be no obstacles that can prevent you from a safe take off and landing. Buildings, trees, electric wires, etc.

Take off area should be clean from large rocks and bushes that can harm the glider. They also prevent the take-off. The slope should be mild.

The landing zone, or LZ. A wide flat grassy field without obstructions like trees and power lines is best. It also needs to be vehicle accessible

Here are some points

  1.  Try checking the wind behavior in the area, use weather maps, radar, and everything available during a long period of time and different altitudes. 
  2. ALWAYS check possible safe landing zones within reach, you'll be amazed at the number of times people take-off wishfully thinking just to end up on a tree or worst.
  3. Pick a time window/conditions up to your level of experience and instruction and make sure someone else knows you are there. Pioneering a new take-off is not for newbies but then again this sport is here in part thanks for the ones who tried, although not all survived.
  4. Always take off from the highest possible point. Sometimes it's coming up the face, but you're actually in the rotor. Flying from the highest point will always help you to know exactly what the wind is doing.
  5. Never fly a ridge that's downwind of another ridge or mountain, even if that mountain is smaller.
  6. Try and avoid taking off between two peaks. The Venturi effect will cause an increase in airflow and you risk getting blown back.
  7. Don't fly a razorback ridge in really strong wind. Getting blown back will dump you in the rotor.
  8. Study the local wind directions and forecasts.
  9. Make sure you have lots of suitable landing spots that are within glide range, taking into account that a headwind will diminish your glide range whilst not necessarily provide the lift to keep you above take off height.
  10. Avoid cliff launches.
  11. Check, and double check again for power lines.
