In 2021, Georgia State Parks introduced a brand new(!) Geocaching challenge, which divides the state into four quadrants, with a separate trackable geo-coin for each.  (You do not have to go to every location in a given quadrant in order to win its coin.)

Each cache contains a "code word" or phrase which you must enter on a "passport" to confirm that you visited the cache.  (If the cache also participated in the earlier State challenge, which relied on "letters," that letter will also be found in the cache box, for those of you who are still pursuing that set of coins.)

The cache-names as listed here reflect those of the caches themselves: the quadrant, and the number of the cache within that quadrant.

A nominal daily entrance fee is required at all Georgia state parks: annual passes are available.
