Agathonisis is a delightful place to spend a few days, walk up to the Chora or further afield. Moor:
drop anchor and tie back to the main quay although this means the wind is usually on the beam, or tie back to the N quay/shore - take care as it gets shallow near the wall so you may not get all the way back.
Anchor: off the beach, but you may get moved by the Port Police if they think you will be in the way of the ferry. You can also anchor in either the East or West bays.
Ashore: tavernas and provisions around the harbour.
