Sardinia’s Trenino Verde (‘little green train’) offers a chance to travel from coast to coast along the Sassari-Tempio Palau line, exploring Costa Smeralda and Riviera del Corallo. As suggested by its name, the train covers a route surrounded by nature according to the principle of sustainability and the most authentic traditions. After a first upward tract through the hills, a slow descent starts toward the River Coghinas: the journey envisages several stops, including the petrified forest of Carrucana in the region of Anglona. This place stands out for its uniqueness and enables visitors to admire the fossil remains of trees which underwent petrification due to a volcanic eruption dating back to twenty million years ago. Finally, the train continues toward the mountainous hinterland and later reaches Costa Smeralda and Palau. This experience is also perfect if you wish to explore the region without giving up your traditional seaside holiday.
