Introduction
Head to the Plemmirio, the most famous marine reserve on Sicily’s southeast coast, just minutes from the historic city of Siracusa (Syracuse). This stretch of shore and sea, officially known as the Riserva Naturale Orientata del Plemmirio, is an outstanding playground for divers, snorkelers and anyone who loves the Mediterranean coastline. Wind-sculpted coves, varied limestone cliffs, underwater walls, Posidonia meadows and rich marine life – groupers, morays, schools of fish and colorful sponges – make Plemmirio a must-visit for anyone wanting to see Sicily from a different angle.
In this comprehensive, practical guide I take you through the Plemmirio experience: how to get there, the must-dive sites, local dive centers with sample prices, plus the rules and handy tips to prepare safe, enjoyable dives. This guide is written for both experienced divers and curious beginners: you’ll find vivid descriptions of the seabed, addresses and typical opening hours of the main centers and services, and local recommendations to get the most out of your outings (best times, usual weather patterns, recommended gear).
Plemmirio can be visited year-round, but the prime diving season runs from May to October, when visibility is best and the water is milder. Expect variable conditions and occasionally strong localized currents, especially on the walls: preparation and respect for reserve rules are essential. To round off your trip, nearby Ortigia and Siracusa’s old town offer cultural immersion after your sea sessions: Sicilian cuisine, fish markets, baroque lanes and archaeological sites.
Throughout this article you’ll find practical details: full place names, exact addresses, typical hours, indicative prices in euros and local tips. Note that prices and schedules can change by season; I recommend contacting operators before you go. I’ve included image markers 
in the most visual sections to help you picture each spot and atmosphere.
The Plemmirio Reserve: overview, access and rules
The Riserva Naturale Orientata del Plemmirio sits on the southeast tip of the peninsula facing the Ionian Sea, east of the city of Siracusa. A useful reference address is Località Plemmirio, 96100 Siracusa SR, Italy. The reserve covers several kilometers of coastline and extends offshore around numerous rocky headlands: Punta Castelluccio, Punta del Pero, Punta del Maremonti, and the well-known Punta del Trippatore. Land access is mainly from the Grottasanta/Santa Panagia neighborhood or via the coastal road coming from Siracusa.
Hours and rules: the reserve is generally open to the public from sunrise to sunset (season-dependent, roughly 06:00–20:00 in summer). Shore-based hiking and snorkeling are free, but scuba diving is regulated to protect habitats. Main rules to know: recreational and commercial fishing is prohibited in large areas, removing marine organisms is forbidden, mooring is restricted and there are regulated zones for autonomous diving. Some areas may require a permit or the presence of an authorized guide.
For boat owners and dive boats, navigation is allowed but subject to minimum-distance protection zones around sensitive habitats (check locally). The reserve management office, or Comando della riserva, can be contacted for the latest charts and instructions; if there’s no clearly identified public office on site, local dive centers and the Siracusa tourist offices provide practical information and the necessary permits.
Local tip: check with the Ufficio Turistico di Siracusa (Tourist Office) at Piazza Minerva, 96100 Siracusa SR for brochures, maps and official contacts. Typical opening hours: 09:00–13:00 and 15:30–18:30 (daily except public holidays). Always obey coastal access signs and avoid leaving any waste; summer surveillance by local authorities is active.
Diving and must-see spots in the Plemmirio
Plemmirio offers a wide variety of dive sites suitable for different skill levels. Here’s an immersive selection of dives you shouldn’t miss, with precise descriptions of the seabed and approximate depths:
- Punta Castelluccio (also called “Secca del Faro”): drop-offs and rocky blocks, 8–30 m. Perfect for spotting groupers, schools of bogue and shoals of gilt-head bream. Visibility 15–30 m in season. Boat access from Marina di Siracusa.
- Punta del Trippatore: a series of caves and overhangs, 5–25 m. An excellent site for photographers thanks to dramatic light and colorful anemones. Currents can be variable; a guide is recommended.
- Secca dei Corvi: a rocky plateau dotted with sponges and Posidonia meadows, 6–18 m. Ideal for introductory dives or deeper snorkel excursions.
- La Cala Lunga (Cala Pisana): small sheltered coves, clear calm water, great for training and shallow dives (3–12 m).
Best times: for optimal visibility and calm conditions, plan dives early in the morning (07:30–11:00) or late afternoon (16:00–19:00) when winds are lighter. In summer, local thermals can create breezes that slightly roughen the surface, but the underwater environment usually remains calm.
Sensory immersion: picture yourself following a wall carpeted in yellow-orange sponges, sunlight filtering through the water column, shy groupers peeking from ledges and morays snug in crevices. The waters around Plemmirio also hide shallower submerged archaeological remnants where you can sometimes spot ancient orphaned blocks – silent traces of the region’s millennia-old history.
Safety tip: observe decompression stops, use a dive computer, and if you dive independently, notify a local center or file a dive plan. Currents can strengthen near headlands; if you feel swept away, surface in a protected area and contact your guide.

Local tips, recommended gear and best practices
To get the most from your Plemmirio dives, follow these local tips and practical preparations:
- Recommended gear: 5mm wetsuit for late summer/spring; 7mm or drysuit for winter outings. Dive computer, torch for cave or night dives, surface marker buoy (SMB) for drift dives, compass and diving knife. Pack water shoes or reef sandals for rocky shore accesses.
- Best time: May–October for optimal visibility and pleasant temperatures (surface 20–27 °C in summer, 15–20 °C in spring/autumn). Outside high season you’ll find lower prices and fewer crowds, but the weather can be less predictable.
- Respect the reserve: don’t touch Posidonia, don’t take anything and avoid contact with corals and sponges. Follow routes designated by guides when diving in protected zones.
- Food and hydration: choose light meals before diving (fruit, simple pasta). Avoid alcohol before diving and stay well hydrated with water and isotonic drinks.
- Useful contacts: Ufficio Turistico di Siracusa, Piazza Minerva, 96100 Siracusa SR (hours 09:00–13:00 / 15:30–18:30), Polizia Provinciale/Capitaneria di Porto di Siracusa for navigation questions (address: Lungomare Alfeo, 1, 96100 Siracusa SR; hours vary).
Local tip: start your day with a dive on the calmest sites in the morning, then, if you’re confident in your skills, try a more challenging dive (wall or cave) around midday. Local guides know micro-conditions and will avoid strong-current areas; follow them for a safe, rewarding session.
