Blue Walls and Hidden Coves: Exploring Plemmirio’s Marine Sanctuary by Boat
Sail, snorkel and watch for dolphins in Syracuse’s rugged marine sanctuary.
You push off from the pale stone quay of Ortigia just as the city yawns awake. The Duomo’s baroque silhouette melts into the low, horizontal light and the water—at first a pewter gray—turns to a glassy, impossible turquoise as the boat eases around the island’s eastern lip. Behind you, the city exhales; ahead, the coastline takes on a new personality. Pale cliffs rise, cliffs cut with caves and teeth—this is Plemmirio: a marine protected area that dares you to read it like a story in rock and reef.
Trail Wisdom
Book a private boat for flexibility
Private charters (4–12 people) let you choose snorkeling stops, pace and duration—ideal for calm mornings or sunset aperitivi.
Bring reef-safe sunscreen
The reserve protects Posidonia meadows—use reef-safe sunscreen and reapply only on the boat to minimize runoff.
Time your swim for calm water
Mornings typically offer the clearest visibility for snorkeling; afternoon thermals can make the sea choppier.
Listen to your guide on anchoring rules
Anchoring and landing are restricted in parts of the reserve—follow local guidance to avoid damaging sensitive habitats.

Conservation Note
The reserve’s regulations protect Posidonia meadows and reef systems—local operators often participate in monitoring and educational snorkeling to minimize impact.
The coast around Syracuse has been fished and navigated for millennia; tonnare ruins mark an old tuna-processing economy that shaped local villages.
Seasonal Guide
spring
Best for: calm seas, wildflower coastal hikes, milder crowds
Challenges: cooler water temps, variable winds
Late spring offers comfortable air temperatures, good visibility for snorkeling as the sea warms, and fewer tourists than peak summer.
summer
Best for: swimming & snorkeling, long daylight cruises, sunset aperitifs
Challenges: peak crowds, hottest midday sun
Summer is prime for water activities—book early and aim for morning or late-afternoon departures to avoid heat and crowds.
fall
Best for: warmer sea after summer, dolphin sightings, pleasant shore walks
Challenges: shortening daylight, occasional storms
Autumn keeps warm sea temps and often calmer water; it’s ideal for full-day trips without high-season numbers.
winter
Best for: dramatic coastal light, budget travel, photo walks from shore
Challenges: rougher seas, many boat services reduced
Winter reveals dramatic light and quieter harbors—boating options are limited and weather can close tours, but shore views remain compelling.
