Karathona is the very beautiful beach of Nafplio and very much worth visiting for a swim, a drink or a good meal on the beach in one of the tavernas.
At the end of the road around the bay there is a big parking place with a small harbour and a church and a house. In the corner starts a foot path to the Chapel of Agios Nikolaos. The walk to the chapel is about 300 m. A, Nikolaos is the saint of the seamen. This chapel is built to protect the boats from heavy waves. The cache is a small jar and is hidden somewhere in a hole in the rocks along the path.
