Monte Adone, mountain summit in the Bolognese Apennines, Emilia-Romagna, Italy

Monte Adone is a mountain in the Bolognese Apennines, in the south-eastern part of Sasso Marconi, reaching 654.44 metres. It is made of Pliocene sandstones and covered with dry xerobromete grasslands and sparse Mediterranean woody plants such as holm oak and alaterno. On its summit are the two Grotte delle Fate, the Grotticella and the Cunicolo Pozzo.

Monte Adone is formed of Pliocene sandstones and lies in the south-eastern edge of Sasso Marconi, in the middle Bolognese Apennines. Its summit, at 654.44 metres, is reached from Brento, a hamlet of Monzuno on the eastern slopes. The mountain is pierced by the 7,135-metre Monte Adone railway tunnel of the Bologna-Florence high-speed line, running from near Pianoro in the Savena valley to Vado in the Setta valley.

The mountain's name comes from Adonis of Greek myth, a reference to the classical tradition that shaped local place names in the Bolognese Apennines. Near the summit, reached from the hamlet of Brento in the comune of Monzuno, visitors find the two Grotte delle Fate, the Grotticella and the Cunicolo Pozzo, natural karst features that draw walkers and cave enthusiasts.

The summit is accessible via a trail starting from the village of Brento, which winds gradually upward and offers multiple viewpoints along the way. Proper hiking boots and weather-appropriate clothing are recommended as conditions in the mountains can change quickly.

The Monte Adone railway tunnel on the Bologna-Florence high-speed line is 7,135 metres long, running from near Pianoro in the Savena valley to Vado, a hamlet of Monzuno, in the Setta valley. Walkers on the summit see no trace of it, though the mountain's streams, chiefly the rio Favale, feed the Savena below.
