Greece's 'Bubble Beach' offers unique volcanic sea experience for tourists

A popular beach on the Greek island of Kos is captivating tourists with an unusual spectacle: the sea appears to boil in certain areas, allowing visitors to swim amidst thousands of bubbles. Known as "Bubble Beach," Paradise Beach in the Kefalos Bay area offers a geological marvel.

The phenomenon stems from volcanic gases, mainly carbon dioxide, escaping from the seabed. Kos, part of the Aegean Volcanic Arc, has a volcanic past, and this geothermal activity is linked to the nearby Nisyros volcano. While the water in the bubbly zones isn't hot, the seabed can feel slightly warm, and unlike other geothermal areas, the gases here lack a noticeable odor.

Clearly marked with buoys, the bubbly spots create a natural "jacuzzi" effect, making it a unique attraction. Paradise Beach is also favored by families for its fine golden sand, clear turquoise waters that remain shallow for a considerable distance, and amenities like sunbeds, umbrellas, bars, and restaurants. The island's volcanic nature means similar geothermal phenomena can be found elsewhere on Kos.
