Mt. Altesina, with its 1,192m above sea level, the highest summit of Erei mountains, feeds the main spring of the river Dittaino. On the summit, there is the relict of a ilex tree wood. Mt. Altesina lies in a strategic area, crossroads in central Sicily. As a matter of fact, in the area there are traces of past settlements, whose finds are on display in the archaeological museum of Palazzo Varisano in Enna. If you love walking and photography, you will find in the reserve of Mt. Altesina some cues for interesting naturalistic observations.
