The seabed produces natural hot water bubbles, a unique geological phenomenon linked to the volcanic activity of the neighboring island of Nisyros.
The water temperature in specific shallow areas near the shoreline can feel warmer than the surrounding Aegean Sea due to geothermal vents.
The island of Kastri, visible from the beach, is accessible by a short swim or by renting a small paddleboat.
The sand composition here is finer and lighter than the pebble-heavy beaches found on other parts of Kos.
Paradise Beach is located on the southern coast of Kos island in Greece, specifically within the Kefalos Bay area. It is characterized by its fine, pale volcanic sand and shallow, crystal-clear turquoise waters. The beach is a popular destination for families due to the gradual entry into the sea. Natural bubbling phenomena occur in the shallows caused by volcanic gas emissions from the nearby active volcano on Nisyros. The beach is highly organized with rows of sunbeds and umbrellas managed by local facilities. Water sports centers operate directly on the sand, offering paddleboarding and windsurfing equipment. A prominent feature is the view of the small islet of Kastri with its blue-domed chapel located directly across the water.

Bring water shoes to navigate the occasional submerged volcanic rock formations near the shoreline.
Arrive early in the day to secure a sunbed, as the most desirable spots near the water's edge fill up quickly during peak season.
Pack a waterproof camera to capture the natural bubbles emerging from the sea floor.
Do not swim too far out toward the center of the bay if you are an inexperienced swimmer, as currents can pick up in the afternoon.
Highly seasonal; most facilities and water sports rentals close completely from late October through April.
Standard beach attire; naturism is not permitted in the main organized zones.
