Euboea, the second-largest Greek island after Crete, lies tantalizingly close to the Eastern Greek mainland. With its rugged mountains, verdant valleys, and extensive coastline, Euboea provides an inviting backdrop for various activities, including scuba diving. Rich in marine biodiversity and dotted with underwater caves, shipwrecks, and unique geological formations, the waters around Euboea are a hidden treasure trove for underwater enthusiasts.

Lihadonisia: Often dubbed the "Seychelles of Greece," Lihadonisia is an archipelago of small islands off Euboea's northwest coast. Beyond its emerald waters and sandy beaches, the underwater environment boasts ancient ruins and various shipwrecks, making it a top choice for experienced divers.

The Caves of Kavos: Near the southern tip of Euboea, these underwater caverns present a labyrinth for divers to navigate. With mesmerizing light play and marine life inhabiting the crevices, it's an experience not to be missed.

Amarynthos Bay: With its gentle slopes and abundant marine life, Amarynthos Bay is perfect for those taking their first plunge. Schools of fish, vibrant sponges, and the occasional octopus are sights that greet novice divers here.

Chiliadou Beach: Noted for its clear waters and sandy seabed, Chiliadou offers a serene diving experience suitable for beginners. The scattered rock formations and seagrass beds provide refuge for a variety of marine organisms.

Euboea's waters brim with life. Divers can spot common Mediterranean species like the damselfish, parrotfish, octopuses, and sea bream. The rocky outcrops may shelter moray eels, while the sandier regions could reveal stingrays and cuttlefish.

Diving in Euboea is best from late spring to early autumn, with water temperatures ranging between 66°F to 77°F (19°C to 25°C). Visibility is generally excellent, often surpassing 30 meters. As with many Aegean locations, winds can affect diving conditions; thus, local forecasts should always be consulted.
