Snorkelling in Alghero

Nestled on Sardinia’s northwestern coastline, Alghero is a gateway to some of the Mediterranean’s most captivating underwater worlds. The town’s historic ramparts overlook a rugged shoreline where limestone cliffs meet translucent blue-green waters, creating an inviting setting for snorkelling. The protected marine reserve of Capo Caccia, just a short journey from Alghero’s old town, is famed for its dramatic caves, hidden coves, and thriving marine biodiversity. Here, the interplay of sunlight and shadow beneath the surface reveals a vibrant palette of colours, from the silvery shimmer of shoals to the deep greens of Posidonia seagrass meadows. Snorkelling in Alghero is not just about observing marine life—it is an immersion into a landscape shaped by wind, salt, and centuries of maritime tradition.

The experience of snorkelling in Alghero is defined by variety and contrast. Guided excursions often begin along the sheltered bays of Porto Conte or the rocky inlets beneath Capo Caccia’s towering cliffs.

Routes may lead you past submerged caves, over sandy seabeds, and through forests of seagrass where octopus, sea bream, and colourful wrasse dart between rocks. The sensation of floating in the cool, clear water, with the muffled sounds of the sea and the warmth of the Sardinian sun on your back, is both invigorating and serene. Whether you are gliding quietly above a reef or exploring the textured walls of a grotto, each moment offers a new perspective on Alghero’s coastal beauty.
