Chioggia's diving is built around two distinct pillars: the tegnue, a network of protected rocky reef formations rising from the surrounding seabed, and a scattered collection of wrecks that have become thriving artificial reefs. Most sites are boat dives at moderate depths, with the intermediate skill level dominating. Marine life leans heavily on invertebrates and ambush predators: European Common Cuttlefish, European Spiny Lobster, Brittle Star, and Scorpionfish are consistent finds, while the Seahorse and Eagle Ray reward patient divers.

Water stays cool through the winter months and into spring, warming noticeably from midsummer into autumn when conditions are at their most comfortable. The peak window falls in late spring and early autumn, balancing warmer water with generally settled conditions. Most tegnue sites are open to currents, so drift potential and visibility can vary depending on the season.

The reefs here are particularly strong for invertebrates and bottom-dwelling species. European Common Cuttlefish, European Spiny Lobster, Hermit Crab, Brittle Star, and Painted Comber are observed very frequently across the tegnue sites. Conger Eel and Scorpionfish are also common, and patient divers occasionally encounter Seahorse, Pipefish, and Eagle Ray.
The majority of sites are pitched at the intermediate level, reflecting the boat access and open-water conditions typical of the tegnue reefs. That said, beginners are catered for at certain sites, including Tegnue Padova and Y-40 The Deep Joy, the latter being a shore-entry thermal pool with platforms at a range of depths in a controlled environment.
Almost all sites require a boat to reach, as the tegnue formations and wrecks lie offshore. The exception is Y-40 The Deep Joy, which offers shore entry as a purpose-built facility. Multiple operators based in the area run boat trips to the reefs and wreck sites, including Venice Diving, Isamar Diving Center, and Albarella Diving Center among others.
The dominant site type is the tegnue, a series of rocky reef formations within protected biological zones that rise from a flat seabed. Several of these also incorporate artificial reef elements. Chioggia also has a handful of wreck dives, including the merchant vessel Evdokia II, the barge Stella Maris, and Peschereccio Ferreo, an iron fishing vessel. The wreck Nave Cannoniera, identified as a tugboat minesweeper, adds an advanced option for more experienced divers.
