Bonatsa Beach Kimolos lies on the southern coast of the island, only 4 kilometers from Psathi port. It stretches right after Aliki Beach, and together they create a long sandy coastline. Because Bonatsa faces south, it stays calm even when strong northern winds affect other parts of the island. Therefore, it remains one of the most reliable swimming spots on Kimolos.

The beach extends for nearly one kilometer. Golden sand dominates the shore, while small stones appear in a few sections. The seabed slopes gently, so the water remains shallow for quite a distance. As a result, families with children feel comfortable spending the entire day here. In addition, wild sea lilies bloom around the edges and enhance the natural beauty of the setting.

Visitors find both organized and free sections along the beach. Umbrellas and sunbeds line specific areas, while wide open spaces allow others to spread their own towels. Changing cabins stand conveniently near the sand. Furthermore, a beach bar provides refreshing drinks and light snacks throughout the day. Several taverns also operate nearby and serve seafood, grilled meats, and local delicacies. 

Accommodation also enriches the area. Bonatsa Beach House, for example, offers modern rooms with private terraces and stunning sea views. Guests enjoy breakfast service and private parking while staying only steps away from the shore. Therefore, travelers who want both comfort and direct beach access often choose this lodging.

Reaching Bonatsa Beach Kimolos proves simple and convenient. A paved road leads most of the way, and a short dirt track connects directly to the beach. Cars and scooters arrive easily, and a parking area lies just behind the sand. Public buses also connect Bonatsa with Psathi and Chora, so visitors without private transport reach it without difficulty.
