Selvaggio Blu
Selvaggio Blu: Ultimate Guide to Italy’s Most Challenging Coastal Trek
Embark on an unforgettable adventure along the Selvaggio Blu, one of Italy’s most spectacular and demanding coastal hikes. This legendary trail leads you through the wild heart of Sardinia’s eastern coastline, where towering limestone cliffs plunge into the shimmering blue waters of the Tyrrhenian Sea. You’ll navigate rugged, mountainous tracks, traverse fragrant Mediterranean maquis, and encounter hidden coves and caves carved by wind and water over millennia.
Widely recognized as the most challenging trekking route in Italy, Selvaggio Blu is reserved for experienced hikers seeking remote wilderness, breathtaking panoramas, and the thrill of raw nature. Each day brings new vistas: sheer rock faces, dramatic ridgelines, and crystal-clear sea views merge for an immersive, back-to-basics journey deep into Sardinia’s unspoiled landscape.
Route Overview
The Selvaggio Blu is a point-to-point trek that typically starts in Santa Maria Navarrese and finishes at Cala Sisine on Sardinia’s eastern coast. Spanning approximately 40 kilometers over 6 days, the route threads through the rugged Supramonte region, closely following the limestone coastline of the Gulf of Orosei. Key locations passed along the trail include Cala Goloritzé, Bacu Mudaloru, Grotta del Fico, Cala Mariolu, Porteddu di Ovile Piddi, and Cala Sisine. Smaller coves, remote plateaus, and shepherds’ shelters mark other significant waypoints.
Trail conditions on Selvaggio Blu are highly variable, with steep ascents and descents, rocky terrain, exposed cliff edges, and sections requiring scrambling or abseiling with equipment. Navigational challenges are amplified by sparse or missing trail markers in many areas, making a topographic map, compass, or GPS device essential. There are no permanent facilities, huts, or established campsites directly along the route, so hikers must rely on wild camping and carry all necessary gear and supplies, including ample water.
Each section of the trail presents unique technical demands, from navigating deep canyons to traversing dense Mediterranean scrub and open cliffside paths. The remote nature of the route means daily progress depends strongly on weather, group experience, and technical ability. While there are alternative exit points at several beaches, most sections are only accessible by foot or by arranging boat pickups in advance, further emphasizing the need for thorough planning and outdoor competence.
Historical Context of the Selvaggio Blu Trail
The Selvaggio Blu is a relatively modern creation in the world of trekking, conceived in the late 1980s by Italian mountaineer Mario Verin and local guide Peppino Cicalò. Their vision was to chart a route that followed historical paths used by shepherds, charcoal burners, and fishermen along the wild and undeveloped east coast of Sardinia. By stitching together these ancient trails and adding technical sections, they established the Selvaggio Blu as an unrivaled challenge for hikers and climbers alike.
While the trail itself is recent, the landscape carries traces of Sardinia’s long human history, with prehistoric nuraghe ruins and centuries-old shepherd shelters dotting the route. For generations, this rugged terrain was accessed only by locals eking out a living from the land and sea, giving the hike a timeless, untouched feel. Today, Selvaggio Blu stands as both a testament to Sardinia’s enduring connection to its past and a showcase of its dramatic, uncompromising wilderness.

Challenges to expect
The Selvaggio Blu is considered one of the toughest trekking routes in Europe due to its demanding terrain and remote setting. Hikers should be ready for extended sections of rugged, rocky paths, frequent scrambling, exposed cliff edges, and technical descents that may require the use of ropes and harnesses for abseiling. Some parts of the trail have limited or no clear markings, placing a premium on strong navigation skills and experience with topographic maps or GPS devices.
The weather in Sardinia can be unpredictable, especially in spring and autumn—the optimal hiking seasons. Intense sun and high daytime temperatures increase the risk of dehydration, while sudden storms may make certain sections slippery and dangerous. Water sources are extremely scarce along the route, so carrying ample supplies for the day is crucial. Due to the remoteness, there are no facilities, and assistance in case of injury or emergency can be hours away, requiring a high degree of self-sufficiency and preparation.
Multi-day wild camping and carrying all necessary food, gear, and safety equipment add to the physical burden. Wildlife encounters, while rare, can include encounters with wild boar or goats, and the dense Mediterranean scrub can make off-trail detours exhausting. Because of all these factors, the Selvaggio Blu is recommended only for highly fit and experienced trekkers accustomed to technical, self-supported multi-day expeditions.

This first day of the Selvaggio Blu begins at Santa Maria Navarrese and follows a coastal path southward to the striking limestone outcrop of Pedra Longa. The route is relatively moderate compared to later days, featuring gradual ascents through maquis and rocky terrain, with expansive sea views along the way. This stage introduces hikers to the wild beauty of the Supramonte coast and ends at a dramatic cliffside camping area overlooking the water.
Day two is more demanding, with technical ascents and descents over rocky trails. The path heads deeper into isolated terrain and requires the first bit of scrambling. Navigating through fragrant Mediterranean scrub and along dramatic clifftops, hikers pass dramatic overlooks before reaching the small bay of Portu Pedrosu, a pebble-strewn inlet suitable for wild camping.
This stage features steep climbs and breathtaking clifftop passages, weaving between dense vegetation and rocks. Hikers will traverse exposed sections and technical scrambles, requiring careful footing and possibly the use of ropes. The reward is the world-famous Cala Goloritzé, celebrated for its crystalline waters and iconic limestone spire, where you can enjoy a well-earned rest in an extraordinary setting.
The most challenging day of the trek, this segment involves multiple abseils, exposed traverses, and very remote terrain with little to no trail marking. Hikers must negotiate deep bacu (gullies) and negotiate some of the wildest, least accessible parts of the coast. The day ends at the stunning Cala Mariolu, a perfect spot for a swim in the turquoise sea and a well-deserved rest.
This stage continues through complex and wild terrain, featuring technical ascents and rope descents intermixed with scenic ridge walks and occasional encounters with ancient shepherd shelters. Dense vegetation, rocky plateaus, and exceptional sea views typify this day, culminating at the small bay of Cala Biriola.
The final stage of Selvaggio Blu traces a rugged and panoramic route before gradually descending to Cala Sisine. Although challenging, this stretch is less technical than earlier sections and offers more sustained hiking along wild ridges and limestone plateaus. The route concludes at Cala Sisine, a broad beach framed by towering cliffs, marking the triumphant end to the adventure.
