The reserve protects the nesting site of the Cory's shearwater, a seabird species rarely seen on the mainland.
The seabed around the island of Capraia features a famous submerged statue of Padre Pio, located at a depth of approximately 10 meters.
The islands are of karst origin, resulting in a complex network of over 30 sea caves, including the notable Grotta del Bue Marino.
Posidonia oceanica meadows found within the reserve act as vital carbon sinks and nurseries for Mediterranean fish species.
The Tremiti islands served as a place of exile for political dissidents during the Roman period and later under the Fascist regime.
The reserve is part of the Gargano National Park system, which facilitates regional conservation efforts.
Water temperatures and clarity in the reserve are significantly influenced by currents coming from the northern Adriatic.
The islands have no permanent large-scale industrial activity, preserving one of the clearest water environments in the Adriatic.
The Riserva Naturale Marina Isole Tremiti is a protected marine area encompassing the five Adriatic islands of San Domino, San Nicola, Capraia, Cretaccio, and Pianosa. Established to preserve Mediterranean marine biodiversity, the reserve is divided into three zones (A, B, and C) with varying levels of environmental protection and access restrictions. The waters are known for the presence of the endangered striped dolphin and dense Posidonia oceanica seagrass meadows. Archaeological remains, including Roman shipwrecks and submerged ruins, are found at various depths within the reserve. The landscape is characterized by limestone cliffs, sea caves, and rocky coves accessible primarily by boat. Regulations strictly prohibit anchoring and fishing in designated 'A' zones to protect fragile habitats. Access to the reserve is managed to balance tourism with ecological conservation. The islands are located approximately 22 kilometers off the Gargano promontory.

Always confirm which marine zones permit snorkeling or scuba diving before entering the water, as 'A' zones are strictly off-limits.
Rent a private boat or participate in an organized tour to reach the hidden coves and caves inaccessible by land.
Apply high-protection sunscreen and bring adequate hydration, as the islands offer minimal shade outside of the main settlements.
Do not attempt to swim into restricted marine zones or cave areas without a local guide, as currents can be unpredictable.
Access to specific protected marine zones is subject to seasonal regulation and potential closure for environmental recovery.
Do not touch, feed, or harass marine wildlife, and refrain from removing rocks, shells, or historical artifacts from the seabed.
