Rules for the Maze:
At each intersection, follow one of the arrows 
on the signs at your right. U-turns are not allowed.
The signs are: A(head), L(eft), R(ight).

Solution:
To solve such a maze it is best to work back from the exit.
It following diagram shows for each intersection the number
of steps necessary to reach the exit. You see that 24 steps
are needed to go from start to exit.
