Everything you need to know about this dive site.
Dive Site Overview
Historically, the waters surrounding Balcony and Alonissos are rich with maritime heritage, exemplified by the ancient shipwreck of the Peristera, now accessible to certified divers. This site, a testament to ancient trade routes, offers dives reaching depths around 15 m (50 ft) with impressive dive times of 48 to 71 minutes.
Beyond wrecks, the region also features dramatic walls and plateaus, such as those found at Mourtias North Reef, extending into the 30 m (98 ft) range from shallower sections. The varied sites ensure each dive presents a fresh perspective on the Aegean's underwater landscape. Water temperatures, particularly in shallower sections, remain a comfortable 26°C (79°F), though deeper dives can see temperatures drop to 20°C (68°F) at depths reaching 30 m (98 ft) or even 18°C (64°F) at 40 m (131 ft).
Divers planning to explore the full range of depths will benefit from monitoring these thermoclines.

Dive Experience & Conditions
A diver's immersion in the Balcony area presents a fascinating contrast of underwater environments. Some sites, like Agios Georgios South Reef, don't demand extensive depth but feature intriguing currents and various swim-throughs. At other locations, such as the Gorgonian Garden, dives can push into advanced limits, reaching considerable depths. Temperatures shift considerably with the underwater topography; surface waters often hold a pleasant 26°C (79°F), yet descending to mid-depths might reveal a cooler 22°C (72°F). The seafloor frequently changes from expansive sandy bottoms, often carpeted with Posidonia seagrass, to dramatic vertical walls. These diverse settings create numerous channels and plateaus, offering dynamic navigation challenges and rich visual exploration for divers across various experience levels.
Dive Difficulty & Safety Guidelines
Navigating the underwater environments of the Balcony region demands strict adherence to safety protocols. Potential for currents and specific architectural features, such as swim-throughs at sites like Agios Georgios South Reef, require excellent buoyancy control and efficient fin kicking. Dive depths vary considerably across sites, ranging from shallow recreational areas to advanced limits, particularly at the Gorgonian Garden where dives can push into advanced technical territory. This variability necessitates meticulous dive planning and careful monitoring of no-decompression limits. Always ensure dives remain within your current certification level and experience. For added safety and to understand local nuances, diving with a knowledgeable local guide is highly recommended.
