Placed in a nice park in Riyadh.
the coordinates of the final stage are on a slip of paper in the first stage (Posted coordinates)
The first stage is the hardest, it is hidden about 3.5 meters up in a climbable tree attached to a branch. preferably you should take a picture of the slip of paper with the coordinates in the tree, please replace knots and tie it back on its branch. The branches have been tested and will hold a person's weight.
Good Luck!
Congrats to Simonbetterton for finding the prize first!
