Swimming marathon of Toroneos gulf
The crossing of Toroneos is a demanding international swimming marathon organized every year since 1970. The athletes start from the beach of Kallithea in Kassandra and finish in Nikiti covering a distance of about 25km. It usually takes place after mid-July and it is more like a local festival as many other events accompany the main swimming event.
The beaches in Sithonia are usually away from the main residential areas. Therefore there are many beach events like concerts and beach parties organized across Sithonia during summertime. Ai Yiannis beach is the closest beach in Nikiti that attracts such events mainly due its remoteness and its large open space.
