Scuba Diving in Ustica, Italy:
A Sea to Sky Adventure
Tucked away in the Tyrrhenian Sea, Ustica is a small volcanic island with a big reputation among divers. Famous for its crystal-clear waters, dramatic underwater landscapes, and welcoming Sicilian culture, it offers a diving experience that feels both adventurous and authentic.

Why Ustica is Italy’s Diving Gem
Why Ustica is Italy’s Diving Gem
Just 60 km north of Palermo, the tiny volcanic island of Ustica is often called the Black Pearl of the Mediterranean. Declared Italy’s first marine reserve in 1986, Ustica has become a bucket-list destination for divers seeking crystal-clear water, dramatic volcanic seascapes, and thriving marine life.
At Sea to Sky, we design curated trips that blend underwater exploration with cultural discovery. In August 2025, I travelled with a small group of six divers – Martin and Sue from America, Bruce and Jo with their children Reg and Dotty, plus my wife Filomena and myself – to explore the best dive sites in Ustica with our trusted partners at Blue Diving Ustica.

Diving with Blue Diving Ustica
Diving with Blue Diving Ustica
Our underwater adventures were made seamless thanks to the excellent team at Blue Diving Ustica. With years of experience guiding divers around the island’s protected waters, their knowledge of local conditions and dive sites is second to none.
From day one, Alessandro and Davide welcomed us with warmth and professionalism, supported daily by Paolo and Elenor – truly one of the friendliest dive teams we’ve met.
Reg completed his Junior Open Water course and Dotty her Bubblemaker – both loved every minute, future divers in the making!
Highlights of diving with Blue Diving Ustica:
We especially appreciated their commitment to safety and conservation. As Ustica is a marine protected area, the team actively promotes eco-conscious practices, helping preserve the island’s underwater world for generations.
For any diver heading to Ustica, we can wholeheartedly recommend Blue Diving Ustica as the go-to dive operator.

Where We Stayed: Stella Marina Hotel
Where We Stayed: Stella Marina Hotel
During our week in Ustica, we stayed at the Hotel Stella Marina, a family-run hotel perfectly located in the heart of town. It was the ideal base — close to the dive centre, harbour, and plenty of restaurants.
Highlights included:
Evenings were spent wandering the piazza, eating gelato, or enjoying seafood pasta and Sicilian wine in nearby trattorias. Stella Marina felt more like a home than a hotel and played a big role in making the trip special.
