It is located 2.5 km west of Megalo Horio in the Agios Antonios settlement. The distance from Livadia is 9 km. The coastal settlement of Agios Antonios with 20 permanent inhabitants, used to be the port of Tilos. Apart from the sandy beach next to the picturesque little port, one can also swim at a pebbled and rocky beach right outside the settlement on the way to Agios Panteleimonas. What is worth mentioning about this beach is the ancient, Byzantine cemetery, which is now covered by the sea but some of its remains can be discerned underwater when weather permits.
The small port of Ágios Antónios is located at the eastern part of the bay’s Plágio head and is the port of Megálo Chorió, which is located in a distance of approximately 2 km to the inland. The small port is open to the southwest and is protected by two moles.
