An irresistible challenge for the adventurous at heart, the Selvaggio Blu Trek (literally the Wild Blue) is a mythical 25-mile trail piercing its way along Sardinia’s rugged east coast. Charged by the Mediterranean sun and invigorated by the breeze of the Tyrrhenian Sea, you’ll traverse this demanding trail on a guided week-long hiking adventure—which also includes scrambling, abseiling, and rock climbing. The rewards are immense and the views unforgettable: massive limestone spires emerging from the sea, agile mouflons relishing stoic juniper trees, rugged coastal cliffs sheltering hidden coves, and golden sandy beaches. Replenish your energy under Italian starry skies and revel in the gratitude of accomplishing this challenging trek.

Often regarded as one of the most challenging treks in the world, Sardinia’s Selvaggio Blu is not for the faint of heart. This 25-mile trail winds its way along the island’s east, rugged coastline, demanding the adventurers to scramble, hike, rock climb, and abseil. With an IFMGA-certified guide by your side, you will navigate Sardinian wilderness safely over the course of a week, and as the day draws to a close, you’ll retreat to a secluded spot for a night under the stars. All the accommodation, food, and transport is settled, so it’s up to you to just enjoy this demanding adventure!

  • Arrive in Olbia, Sardinia. There’s an evening transfer from the Olbia Airport to your accommodation for the next 2 nights—a 3* hotel in Cala Gonone, just 200 m (650 ft) from the beach. Meet your guide and the rest of your team for a meet and greet session and a technical introduction.
    Accommodation: 3* hotel in Cala Gonone
    Luggage access: Yes

    Cala Gonone, Sardinia

  • Today includes a half-day session for rope skills training in a rugged canyon in the Supramonte region. The series of training abseils will gradually get more challenging, simply to make sure everyone is confident with abseiling. Return to Cala Gonone and explore the town on your own—try out pizza, local wine, or gelato. Tomorrow the trek begins.

    Harness on a beach in Sardinia

  • Transfer to Pedra Longa to begin the trek. Enjoy your first, relatively-non-technical day except for a short upwards scramble (though usually not required, it may be roped so harnesses and ropes will be carried just in case). There will also be downclimbing a short section via a juniper tree attached to the mountainside. Tonight you’ll sleep out (bivouac) under the stars, in a small clearing near rocky Portu Pedrosu. A crew will arrive by boat to deliver water and supplies.
    Accommodation: Bivouac
    Luggage access: No

  • Juniper trees and branches will aid your progress today—they’re living history, as locals have engineered and worked with this hardy tree in this manner for centuries. You’ll also come across Sardinian shepherds’s hut enroute, called “oviles”. Going up and over Punta Salinas, you’ll pass through the spectacular UNESCO World Heritage beach of Cala Goloritzè, famous for its monumental rock spire and azure seas. Have your second food stop as there’s 2 more hours left of trekking today (with 2 roped climbing sections) to take you to the wild bivvy spot up on the plateau of Piredda. The crew will greet you there and resupply.
    Accommodation: Bivouac

    Cala Goloritzè beach

  • More technical climbing and abseiling begins today! The first part of the day is spent trekking, dropping down to the sea. Then you’ll have a few short abseils scattered across the whole afternoon before you reach the bivouac point for the night—which is a cave. The route will take you from Punta Salinas to Bacu su Felieu with some elevation change to tackle.
    Accommodation: Bivouac
    Luggage access: No
    Meals: Not included, you bring a dehydrated meal for tonight
    Hiking: 6 hours

    Juniper trees, Selvaggio Blu

  • Abseil from the bivouac spots and trek for a couple of hours. You’ll have 2 longer abseils in the afternoon, and later on you’ll have some chained sections, climbing sections, and shorter abseils. If you’re lucky, you’ll spot the local Sardinian mouflon, tenacious characters able to negotiate impossibly steep terrain. Gaze down over the Mediterranean pristine turquoise waters as you lower your way down to the beach, where you’ll enjoy a locally-sourced dinner. There’s a planned boat resupply.
    Accommodation: Bivouac

  • This last non-technical day is a perfect end to your trek. Sea permitting, the crew will arrive to take the climbing kit to make your daypacks lighter. Enjoy this morning’s final section of the trek as you hike to Cala Luna for a celebratory lunch on the beach. Relax on the spectacular boat trip over the Cala Gonone to spend the final night at a hotel

    Cala Sisine, Sardinia

  • There will be a private group transfer back to Olbia this morning after breakfast, which gives you a great opportunity to explore Olbia before heading back home. Time permitting, enjoy those last few hours on the beautiful beaches of Olbia or soak up the local history, views, and cuisine. If you’d like to stay longer, just ask your guides for some recommendations!
    Meals: Breakfast

  • This itinerary is designed to complete the Selvaggio Blu Trek in a relatively self-contained way—this means minimal resupply points, some of which are dependent on sea conditions. Please be aware that if the sea does not permit small vessels to reach beaches as planned, then more food and water will need to be carried, and Day 7 could potentially involve heavier day sacks.

  • Often described as one of the most challenging treks in the world, the Selvaggio Blu Trek is a 40-kilometer (25-mile) route running along the east coast of Sardinia that demands excellent fitness. This is a tough trek on a rough trail with steep climbs and scree descents. Daily distances are between 7-12 km (4-7.5 miles) with ascents and descents of up to 1,000 m (3,280 ft) as well as abseiling and climbing sections.

    In order to join this tour, you must have excellent fitness and not be afraid of heights. Keep in mind that you’ll be carrying a 10-15 kg bag (22-33 lbs). Previous experience with climbing and abseiling is essential (putting yourself onto a prepared abseil rope, though your IFMGA-qualified guide will provide instruction on the ropes section). Any experience with via ferrata, wild camping, and cooking by stove is not necessary, but more than welcome.

  • Here’s a list of the equipment you need to bring:

      • Backpack large enough to carry all the items listed + some group equipment (around a 45-60L bag)
      • Hiking poles — optional
      • Week’s worth hiking clothing
      • Water bottle or hydration bladder (2L capacity)
      • Lightweight hiking boots or shoes
      • Spare clothes for layering
      • Waterproof rain jacket
      • Sunhat
      • Toiletries (sunscreen, hand sanitizer, bug spray, toilet paper, etc.)
      • Headlamp or flashlight
      • Sunglasses
      • Camera — optional (but recommended)

    Dress comfortably and for the weather in clothes you can move in. We suggest bringing clothing appropriate for the season. Layers are best and don’t wear jeans.

  • This adventure along the Selvaggio Blu Trek is designed in a way to make sure you’re well-rested and prepared prior to starting the trek. This involves staying at a hotel for the first two nights, at which time you’ll have access to all your luggage.

    However, as soon as you start your trek (on Day 3), you’ll only carry what you need for the duration of those few days while sleeping under the stars. You’ll be sleeping in bivvy bags with a large tarpaulin, and you’ll have to carry your personal belongings as well as a share of the group equipment. You can expect your backpack to weigh between 10-15 kg (22-33 lbs), so make sure you have a backpack large enough to carry everything you need. You’ll have access to the rest of the luggage as soon as you end your trek, which is on Day 7 when you’ll get a good night’s sleep in a hotel.

  • Group sizes and prices:

      • For this guided hiking tour along the Selvaggio Blu Trek, the maximum client-to-guide ratio is 8:1.
      • It takes a minimum of 4 people for this tour to operate, and 8 is the maximum group size.
      • The cost does not decrease as the group grows.

    Min. age requirements:

      • If you are older than 18, you’re good to go.
  • To get to Sardinia, fly into Olbia Airport (OLB), where your guides will come pick you up. There will only be one (evening) group transfer from the airport, so your guide will let you know at what time at the latest you have to land.
