Moni is the small uninhabited islet off Aegina's southwest coast, reached in season by boat from Perdika. Its draw is simple: clear water, pine shade, rocky coves, and a sense of leaving the main island behind for a few hours.
Do not expect village life or much infrastructure. This is a swim, snorkel, and picnic sort of place, with resident animals often wandering near the beach and enough paths to stretch your legs before catching the boat back.
