The coordinates given are not the actual coordinates of the
cache, but of an entrance (with some parking) to Dasos Syggrou,
where the cache is located. Dasos Syggrou is a lovely small forest
to the north of Athens, very close to the Marousi Metro station.
Entrance is free, but it closes down at sunset. It is an ideal
place to walk (alone or with the dog), jog, etc.
To find the actual coordinates, you will need to solve this
Sudoku puzzle. The standard Sudoku rules apply: You must fill the
boxes with the digits 1-9, and each digit must appear exactly once
in every horizontal row, vertical column, and block of 9 boxes.
The cache coordinates are:
N 38° 0(H1).(C2)(G4)(F6)
E 23° (A3)(I9).(A7)(E9)(C7)
The cache difficulty rating of 2* reflects the difficulty of the
Sudoku puzzle (medium).
The cache is a tupper container hidden under a tree, behind a
small fallen log. It is in a plastic bag and is covered with a
couple of rocks.
