Between Saddle and Sea: Exploring Devil's Saddle (Sella del Diavolo) by Boat and Shore
Coastal caves, snorkeling in turquoise water, and a short ridge trail—experience Cagliari’s most dramatic promontory by sea and shore.
You feel it first in the light: a blunt, white cliff sharpening against Sardinia’s cobalt, the skyline cleaved into a profile locals call the Sella del Diavolo—Devil’s Saddle. From the deck of a small RIB the promontory reads like a weathered spine of limestone and scrub, its caves yawning at water level and its jagged flank reflected in water so clear you can see the dark fans of Posidonia seagrass swaying like anemones. Out here, the city of Cagliari recedes into pastel rooftops; the Gulf of Angels opens up, and the island becomes an invitation to move between two elements—sea and rock.
Trail Wisdom
Book morning departures
Calm seas and clearer water make early tours best for snorkeling and photography.
Protect Posidonia meadows
Choose operators who avoid anchoring on seagrass and follow guidance to avoid damaging the seabed.
Bring reef shoes
The rocky shoreline and some cave entry points are sharp; water shoes protect feet when boarding or swimming.
Layer for sea spray
A light windbreaker is useful on open-deck boats—wind and spray cool you quickly after a swim.

Conservation Note
Posidonia oceanica meadows in the gulf are protected; responsible operators avoid anchoring on seagrass and emphasize no-touch snorkeling.

Seasonal Guide
spring
Best for: calmer seas, wildflowers on the ridge, shoulder-season boat rates
Challenges: cooler water temperatures, variable winds
Late spring offers warming water and fewer crowds; mornings are typically calm for snorkeling and photography.
summer
Best for: warm water, long daylight, sunset aperitif cruises
Challenges: crowds on popular tours, strong midday sun
High season brings regular departures and lively afternoon tours—book ahead and plan for sun protection.
fall
Best for: clear water after summer heat, less crowded tours, comfortable hiking temperatures
Challenges: possible windy days, shortening daylight hours
Early fall balances warm sea temperatures with smaller groups, making it an ideal time for combined hikes and boat trips.
winter

Challenges: chilly water, fewer boat services, occasional rough seas
Boat availability is limited but the ridge trail is peaceful; check with operators for winter departures.
