Route II
(Published on 4. February 2009, 21:51 by Richard)
Draw black squares in empty cells so that every arrow points exactly to the corresponding number of black squares. Black squares can only be adjacent diagonally. All the remaining white cells form a single closed loop that doesn't cross or overlap itself. A cell cannot be black if there is not pointing an arrow at it.

This took me hours. Until I realized that I just misunderstood the rules:
The loop does not go through the squares with numbers.
