Kalloni is a quiet market town about 40 km west of Mytilini, sitting at the intersection of most of the island's bus routes. The beach resort of Skala Kalloni lies about 3 km south of the old town at the head of the Gulf of Kalloni. The long, gently shelving beach is one of the better options on Lesbos for families with young children — the water is shallow and warms quickly in summer.
The gulf and its surrounding wetlands are famous among birdwatchers across Europe: flamingos, spoonbills, waders, and rare migrants gather here in spring numbers that have made Lesbos one of the top birding destinations in the eastern Mediterranean. The main sight in the area is Limonos Monastery, about 7 km away, a substantial 16th-century complex with a good ecclesiastical museum and a fine old library. Other attractions nearby include the Temple of Aphrodite at Mesi, about 14 km east on the southern shore of the gulf.
