Go for a stroll by the water and breathe some fresh air at Hydra Town Harbour. It's always relaxing watching the boats coming and going.
Hydra Town Harbour is free to enter, so you can have a great day out in idhra without opening your wallet. Once you've finished at this place for ships to anchor, head to some of the area's other sights. Mandraki Beach, Manor of George Kountouriotis and Hydra Merchant Marine Academy will keep you busy.
