Sardinia is a precious natural resource, containing thousands of rare or uncommon animals and plant species such as the Mediterranean Monk Seal and the boar. It lacks many common species instead, like the viper and the marmot, which are found everywhere else on the continent.
    Trains on Sardinia connect the whole island but are rather slow. Some run on narrow gauge track. Many tourists catch the trenino verde which runs through the wildest parts of the island. It is slow but it allows the traveller to have scenic views impossible to see from the main road. The train connects Cagliari to Arbatax in the south and Sassari to Palau in the north.

    It is highly recommended to make the trip from Macomer to Bosa Marina, where the train winds its way through the typical Sardinian landscape to reach the sea near the coastal town of Bosa situated in the west of the island.
