everyone; they wanted to avoid climbing and abseiling, adding vie ferrate (that can be found in the alps) when it was unavoidable. This has not been done yet, but the itinerary has been made easier as some exposed sections had led to the fixing of ropes and chains even if it's not necessary; this compromise leaves the lack of way making (which is the major difficulty) untouched. It is possible to see Sardinian mouflon over the rocky steps of the itinerary of the last day. During the summer or hot days it is possible to see them in the late afternoon of the evening, while on cold days or in winter they can be seen during the day. They are well adapted to uneven ground of the mountains, because of their muscular body they can climb steep rock walls and they can run at 60 km/h. The male can weight 50 kg, while the female usually weights 25 kg; these mouflons are present in Sardinia since Neolithic times. Many mule tracks that could have been seen and used by trekkers have disappeared because they have been covered by dense vegetation. The paint of the blue waymarking in the last part of the itinerary has been recently renewed by a walker, to help other trekkers. Once a group walked the entire itinerary of Selvaggio Blu barefoot. A trekker, Nicola Bassi, winner of the 90 km Ultratrek, finished the route in only 8 hours and 10 minutes, without any external help and without stopping by to sleep or rest. Lonely Planet has mentioned Selvaggio Blu in its 2015 article "Italy's seven best hikes: majestic mountains, dramatic coastlines and smouldering volcanoes" Some transport services are offered by local companies to support the trek. The walkers who tackle Selvaggio Blu can make arrangements to receive supplies every evening, so as to be able to walk with a lighter rucksack. The equipment is usually delivered in the evening and collected the following morning. After that, it is taken to the next spot. This service is available only when the sea is not rough; under these circumstances, it would not be possible by land. Guides The guides that conceived the trek are: Mario Verin: a photographer specialized in landscapes, who is also an alpinist. He focused his explorations in Sahara and in the Middle East. He studied in Florence, where he first met Peppino Cicalò, with
