Cala Mariolu is a beach in Cala Gonone, Sardinia (Italy). It is sheltered from the maestrale and ponente winds.
White pebbles like pigeon eggs and water that fades from turquoise to cobalt blue: Cala Mariolu is regularly listed among the most beautiful beaches in the world. Accessible only by sea or via a challenging trek.
Cala Mariolu is one of the most enchanting coves in the Gulf of Orosei, known for its white pebbles resembling small eggs and for a sea that shifts from turquoise to deep blue. Nestled between the high limestone cliffs of Supramonte, the beach is entirely made up of gravel and smooth pebbles shaped by marine erosion, giving it an unmistakable light color. The water, crystal clear due to the scarcity of suspended sand, allows you to see the seabed even a few meters deep: an ideal condition for those wanting to snorkel right from the shore or explore the submerged rocky walls.
The most convenient way to reach Cala Mariolu is by boat: daily excursions and motorboats depart from Cala Gonone, Santa Maria Navarrese, and the ports of Baunei. The vessels coast along the limestone cliffs of Supramonte, often passing in front of the marine caves of the Gulf of Orosei such as the Grotta del Bue Marino, and allow for multiple stops throughout the day. The boat remains the most practical option also because there are no fixed services on the beach: those arriving by sea bring their own water, food, and equipment for the day.
An alternative for hikers is the land trek: the most frequented route starts from Baunei across the plateau of Golgo and descends towards the coast through paths in Supramonte. It is a demanding route, with significant elevation changes and stretches on limestone, suitable for those with experience and good physical training. The trek offers a privileged view of the coastal cliffs and the advantage of arriving when boat trips have already departed, but requires careful preparation: bring plenty of water, sturdy hiking shoes, and check the trail conditions before setting off.
The best time to visit Cala Mariolu is between May-June and September, when the sea is calmer, the crowds are fewer compared to the peak months, and boat trips are regular. In July and August, the cove is very busy and boat outings fill up quickly: booking a few days in advance is almost essential. The area is part of the protected coastal system of the Gulf of Orosei: it is vital to respect marine conservation rules — do not collect pebbles or fauna, do not step on posidonia, do not leave waste — to preserve an environment that owes its beauty to the lack of excessive human impact.
The most common way to reach Cala Mariolu is by boat: excursions and motorboats depart every morning from Cala Gonone, Santa Maria Navarrese, and the ports of Baunei throughout the summer season. Daily outings usually last 6-8 hours and include stops at several coves in the Gulf of Orosei. During high season, it is advisable to book a boat spot the day before, as trips fill up quickly; many operators allow online or phone reservations.
Alternatively, the land trek starts from the plateau of Golgo above Baunei: the path winds for several kilometers on Supramonte trails with significant elevation changes and stretches on limestone rock. It is a route suitable only for experienced hikers with good physical preparation, adequate equipment, and plenty of water reserves. Those arriving by car can leave their vehicle at Cala Gonone, Santa Maria Navarrese, or in the parking areas at Baunei before embarking or starting the trail.
- Book your boat spot in advance during high season: trips from Cala Gonone and Santa Maria Navarrese often fill up on the same day.
- Bring water, food, and sun protection: there are no bars or services on the beach.
- Bring water shoes: the pebbles are smooth but slippery out of the water and near the rocky walls.
- For trekking, choose the early morning hours and inform someone of your route; do not set off alone in uncertain weather conditions.
- Avoid collecting pebbles, shells, or marine fauna: it is prohibited and harms a fragile ecosystem.
- Check the wind forecast before departure: the maestrale can make the sea rough and cause boat excursions to be canceled.
The best time is May-June and September for calmer seas, fewer visitors, and regular boat excursions; July-August are very crowded and require advance booking for trips.
