Frequently Asked Questions

Plan most scuba trips between May and October. July and September offer the best overall balance: July has long days, warmer water, full services, and a local reputation for larger fish moving shallower, while September retains warm water and adds pelagic passage potential with fewer land crowds than August. May can be cold below the surface layer, and October brings more variable weather. August is warm but busy, so reserve rooms, ferries, equipment, and boat slots early. Keep one spare dive day for wind, current, or marine-park site substitutions.
Four to six nights is a practical first trip. That normally allows three or four dive days, one flexible weather or ferry buffer, and time for , Villaggio dei Faraglioni, or a cave-coast boat circuit. A shorter stay risks losing the signature mix if an exposed site such as is swapped. Divers targeting deeper walls, wreck routes, macro subjects, or approved cave objectives should stay longer because qualifications and conditions determine the schedule. Protect the final flight with a Palermo night and follow the required no-fly interval.
Fly into Palermo Falcone Borsellino Airport, then use the airport train, scheduled coach, taxi, or private transfer to Palermo port. The road leg is about 35 km. Liberty Lines fast craft commonly takes about 1 hour 30 minutes to Ustica, while the conventional ferry is closer to 3 hours. Check the exact terminal, check-in deadline, baggage allowance, and sailing on the official operator site. Do not build a tight flight-to-ferry connection, and use a Palermo buffer on the return because wind can delay or cancel crossings.
Yes for private activity in Zones B and C. The 2026 rules require an activity-specific authorization, certification evidence, payment, and compliance with designated sites, buddy, float, group, and safety limits. The published individual fee is EUR 6 per dive or EUR 50 for ten dives for both scuba and apnea. Zone A is closed to recreational scuba and apnea. Visitors booking an authorized guided center normally operate under that center's permissions, but should still ask what the package includes. A scuba permit does not automatically authorize freediving or private cave access.
Yes, provided an authorized operator selects sheltered, shallower routes and keeps the group within the diver's certification and recent experience. Secca d'Africa, parts of Punta Falconiera, Grotta Pastizza outside any overhead section, and selected coves can offer approachable profiles. The island is not uniformly easy: Secca della Colombara, deep gorgonian walls, strong-current days, wreck depth, and caves belong to more experienced plans. A beginner should disclose air consumption, comfort in current, last dive date, and equipment needs, then accept site changes rather than insisting on a famous objective.
Start with Scoglio del Medico for multi-route volcanic structure and fish life, then add Secca della Colombara for its shallow crown, exposed pelagic edge, and cargo wreck. Punta Falconiera combines archaeology, wall, and ravines near the harbor, while Punta dell'Arpa offers deeper gorgonian terrain for advanced divers. Secca d'Africa is a useful shallower shoal, and Zia Lisa adds canyon and light effects. Properly qualified overhead divers can discuss Grotta dei Gamberi, but the marine park restricts cave diving to authorized guided activity. The best actual site is always the one that fits the day's wind, current, reserve capacity, and group level.
Only under the marine park's controlled system. The 2026 regulation prohibits private cave diving and requires an authorized guide, appropriate cave qualification and equipment, daytime operation, and a maximum of four divers per guide. From June through September, guided cave diving is scheduled only in the first and third weeks of each month; outside that period it is permitted daily subject to authorization and conditions. Grotta dei Gamberi begins around 38 m to 40 m and is a deep, high-difficulty overhead objective. Send credentials and equipment details to the operator before booking travel.
Use a current guide or marine-park direction rather than assuming every attractive cove is open. In the integral Zone A, the 2026 regulation names Cala Sidoti and Cala Santoro for authorized guided seawatching. Zones B and C offer broader possibilities, including guided outings around volcanic coves such as Zia Lisa or Grotta Pastizza, but sea state, vessel lanes, local ordinances, and access conditions still matter. Rock entries can be slippery and surge can build against cliffs. A guided trip adds flotation, surface signaling, route selection, wildlife interpretation, and legal access knowledge.
Non-divers can walk the Punta Falconiera and Punta Gavazzi coastal itineraries, check the reopening status of the fortified Middle Bronze Age Villaggio dei Faraglioni, explore its coastal context if closed, explore village murals and local collections, rent a bicycle or scooter, and join a calm-weather boat circuit of sea caves. Guided seawatching at Cala Sidoti or Cala Santoro gives a marine-reserve experience without scuba. April to June and September to October are best for longer walks. In July and August, start early, carry water, avoid exposed midday routes, and use the afternoon for village time or a pre-booked shaded activity.
ASP Palermo lists a Ustica hyperbaric chamber operating seasonally from May 1 through October 31, alongside the island outpatient facility. Treat that as planning information, not a guarantee of day-by-day readiness: confirm current status with the operator and local health service before diving. Serious cases may still require weather-dependent transfer and coordination with Palermo-area hospitals. Carry specialist dive insurance and know 112, Coast Guard 1530, and the DAN Europe emergency line. In suspected decompression illness, give oxygen if trained, keep the diver at rest, and seek professional help immediately.
A 5mm to 7mm wetsuit covers many visitors during the May to October season, but personal cold tolerance, dive duration, depth, wind, and repetitive diving matter. Early May water can feel notably cold at depth, so trained drysuit users or cold-sensitive divers may prefer a drysuit. Summer surface water can reach about 26°C to 28°C, yet deeper layers may still justify a hood or vest. Ask the operator for the current temperature profile and rental thickness, and pack exposure protection for boat intervals rather than choosing from air temperature alone.
The marine protected area identifies Posidonia oceanica, dusky groupers, bluefin tuna, amberjacks, barracuda, octopus, and spiny lobsters as characteristic life, while local site descriptions add nudibranchs and other macro subjects. July is locally associated with some larger fish moving shallower, and September with passing pelagics, but none is guaranteed. Exposed shoals and blue-water edges may favor predator encounters, while walls and caves reward slower observation. Do not feed, chase, touch, collect, or reposition animals for photographs; the protected habitat is the reason the wildlife remains compelling.
