If being by the water is a major draw, Sani Beach is a spot you might want to check out, located 6.4 mi (10.3 km) from central Kassandra. Catch the sunset by the shore at Boúsoulas, just a short walk away.
You can learn about the history of Kallithea with a visit to Temple of Ammon Zeus. Stroll along the area's beaches or simply enjoy its restaurants.
