The outer part of the harbour is of an emerald coloured translucent water (not august & July due to motor boats). Ashore:
Bakeries, mini market and good tavernas. Try Makis spit roast lamb; Dionysos restaurant. Jackie and Eric's for vegetarian food. ATM, bakers, supermarket.
Walk round the bay as far as you can past Harami Taverna out to the point where the exposed NW beach is so close to the sheltered bay.
Don't leave your rubbish in the small rubbish bins. Follow the signs just out of town to the rubbish bins.
