Agios Sostis Beach Serifos lies on the eastern coast of the island and offers a peaceful, untouched escape for visitors. Unlike the more popular beaches on the island, Agios Sostis remains quiet and free from crowds. The beach stretches along a narrow bay, covered in soft golden sand and framed by rocky hills. Crystal-clear, shallow waters create excellent conditions for swimming and snorkeling. 

A small white chapel, also named Agios Sostis, overlooks the beach from a nearby hill. Many visitors climb up to the church for sweeping views of the bay and great photo opportunities.

Although the beach offers stunning beauty, it lacks modern facilities. There are no sunbeds, umbrellas, or beach bars here. Therefore, visitors should come prepared with water, snacks, and any beach gear they may need. Bringing an umbrella or some other form of shade is also a smart idea, especially during the hot midday hours.

To reach Agios Sostis Beach Serifos, visitors have to drive along the eastern coastal road until they spot the signs pointing to the beach. Parking is available near the chapel and then a short walking trail leads down to the shore. The path includes some uneven and rocky sections, so sturdy shoes will make the walk easier and safer.

Because of its remote feel, the beach appeals mostly to couples, solo travelers, and nature lovers. Travelers looking for nightlife, loud music, or organized activities will not find them here. Instead, they can enjoy the soothing sounds of the sea, the soft breeze, and the stunning views.
