Antonides Beach in Kythnos rests on the southeastern coast of the island, near the peaceful village of Panagia Kanala, about 11 km south of Chora. Although it is close to popular spots, it stays quiet and less crowded. The beach sits in a small cove, surrounded by dry-stone terraces and rocky hillsides. 

The shoreline combines soft sand with small pebbles. The bay stays sheltered from strong winds, so the sea remains calm most of the time. Additionally, a large flat rock extends into the water. While it adds to the scenic beauty, it creates a slippery surface. Therefore, most swimmers choose to enter from the edges of the beach.

To reach Antonides, visitors must park in Panagia Kanala and continue on foot. A narrow path winds through stone walls and small homes. After that, about 90 stone steps lead down to the beach. The walk takes only a few minutes, but it requires good footwear and steady footing. Also, since the beach is small and can fill up quickly, arriving either early in the morning or in the afternoon ensures a more enjoyable exeprience.

Antonides lacks organized services. There are no sunbeds, umbrellas, or beach bars. For this reason, visitors should carry everything they need, including water, food, sunscreen, and towels. Reception can be weak in this area, so travelers should plan ahead and communicate before arriving. Also, the beach also lacks lifeguards, so extra caution is necessary while swimming.

Nearby, the village of Panagia Kanala adds convenience. It features a few tavernas, cafés, and small hotels. The church of Panagia Kanala, one of the most important on the island, also sits just a short walk away. After enjoying the beach, visitors often explore the area or stop for a meal in the village.

Overall, Antonides Beach suits couples, solo travelers, and nature lovers. Those seeking quiet, simplicity, and natural charm will find this beach a rewarding stop on their island journey.
