Koumelas Beach, located on Tinos Island's northwestern coast in Greece's South Aegean region, offers a secluded escape with pebbly shores and deep turquoise waters[2][4]. Nestled near marble quarries, the beach provides a rugged landscape with natural shade from trees and views of Andros Island across the strait[2][5]. The area maintains a quiet, uncommercialized atmosphere, appealing to travelers seeking serenity away from crowded tourist spots[4][5]. Family-owned rental houses near the shore enhance its intimate, community-focused vibe[4].
