Cala Sa Figu

Tucked into the wild Sarrabus coastline near Muravera, Cala Sa Figu sits between granite cliffs draped in Mediterranean scrub. Also known as the Bay of Amphorae, after the Roman terracotta fragments found nearby, it has a crescent of white and grey sand, shallow turquoise water, and almost no visitors even in high season.

Hiking and mountain bike trails run through the surrounding maquis, and the beach itself feels genuinely remote despite being reachable by car.

Good to know: no facilities on site. Bring water, food, and sun protection.

Spiaggia di Piscinas

Nothing quite prepares you for Piscinas. The beach is backed by golden sand dunes reaching up to 60 metres, shaped over centuries by the Mistral wind. The coastline here stretches for around 7 kilometres with almost nothing built on it. It feels less like a beach and more like a desert that ends at the sea.

It stays quiet because it takes effort to get there. The access road is unpaved for several kilometres and there are no towns nearby. Strong currents make swimming better suited to confident swimmers, but the landscape alone is worth the journey.

Good to know: a small bar operates on site in summer. Expect a rough dirt track for the final stretch.

Cala Domestica

Cala Domestica is one of the more accessible wild beaches in southwest Sardinia, which means it does get busy at peak hours. But timing changes everything. Arrive early in the morning or return in the late afternoon and the cove feels like a different place entirely. The light is softer, the cliffs seem taller, and the crowd has gone.

Good to know: aim for before 9am or after 5pm in July and August.

Porto Palmas

A small sheltered cove near the ghost village of Argentiera, once a silver mining settlement. Two headlands protect the bay from the Mistral, making the water calm and clear and ideal for snorkelling and families. It sits in the province of Sassari, about 25 kilometres from the city, and sees far fewer visitors than the beaches around Alghero to the south.

Good to know: free parking nearby. A small bar operates in season. Holds a Blue Flag for water quality.

Cala Sisine

The Gulf of Orosei is Sardinia's most dramatic stretch of coastline, but not all of its beaches get equal attention. Cala Sisine is quieter than Cala Luna or Cala Mariolu, yet it offers the same essentials: fine sand, turquoise water, and sheer limestone cliffs. It is also the finishing point of the Selvaggio Blu, one of Italy's most demanding long-distance trails.

Getting there by boat or on foot takes effort, and that effort is what keeps it peaceful.

Good to know: no facilities at the beach. Bring everything you need. Boats depart from Cala Gonone and Santa Maria Navarrese.

Is Arutas

Is Arutas is unusual enough to have built a reputation: the sand here is made of tiny quartz grains, pale and almost pearlescent, unlike anything else on the island. Most visitors park and stay close to the main entrance, which is where the crowds concentrate. Walk further along the shore and space opens up quickly, even in the middle of summer.

Good to know: Access is regulated in peak season to protect the beach. Check current rules before visiting.

Cala Fuili

A compact pebble cove near Cala Gonone, reachable by car and a short walk. Because most visitors prefer sandy beaches, Cala Fuili tends to stay quiet even when nearby spots are packed. The water is calm and turquoise, the surrounding cliffs are dramatic, and for those who want to push further, it is also the starting point for the hiking trail to Cala Luna.

Good to know: good for snorkelling. Services are available in Cala Gonone, about a kilometre away.
