Why dive here
With 44+ marine species recorded in the area - including dolphins, ocean sunfish (mola mola) and sea turtles - ASTREE offers some of Costa Brava's richest wreck diving. Water ranges 11-24°C, warmest July, August, September.
The Astree, a motor vessel, sits upright in 38 metres off the Costa Brava, making it one of our favourite deep wreck dives in the Med. Dropping down, the first thing you notice is the sheer size of the hull appearing out of the blue, often with schools of barracuda hanging just off the deck. We love that you can swim right into the cargo hold, where light filters through openings, illuminating lobsters tucked into corners and conger eels peeking from pipes. It’s a proper exploration dive, with plenty of external features to circumnavigate – the bow, the stern, and the superstructure are all intact enough to give a real sense of the ship. We’d suggest a torch for peering into the darker recesses; you’ll often find scorpionfish camouflaged on the deck plates. This site suits experienced wreck divers who appreciate a relatively undisturbed historical wreck, rather than those seeking vibrant coral gardens. Expect a thermocline around 15-20 metres, so a decent wetsuit is a good idea, even in summer.

ASTREE Wreck History
Vessel Type
cargo ship
Cause
unknown
Resting in the deep blue waters of Spain's Costa Brava, the Astree is a mystery wreck for advanced divers. Little is known about the history of this motor vessel or the circumstances of its sinking. Its name, French for 'starry', hints at a possible French origin, but its story remains submerged with its steel hull. The wreck is classified as 'dangerous,' suggesting it may be unstable, broken, or present entanglement hazards from lost fishing gear.
Sitting at 38 meters, this dive requires careful planning and is best suited for experienced divers with deep and wreck certifications. The depth means bottom time is limited, so every moment counts. The vessel's structure has become an artificial reef, attracting a rich diversity of Mediterranean marine life. Divers often encounter large schools of fish, conger eels, and colorful invertebrates that have made the silent, shadowy corridors of the Astree their home.
