Panigiri of Agios Ioannis Spiliotis at the Cave
7–8 May · Agios Ioannis (Cave of Antiparos)
The chapel of Agios Ioannis at the mouth of the famous cave celebrates St John the Theologian on 8 May, with vespers on the 7th and a panigiri on the terrace outside: traditional dances, kerasmata, local dishes and wine. It is Antiparos's best-known feast and a rare chance to be at the cave with locals rather than tour groups.
