Monte Acellica, Mountain summit in Campania, Italy

Monte Accellica is the highest summit of the Picentini group in the Campanian Apennines, rising to 1,660 m as Accellica Nord. It stands between Monte Terminio to the north, Pizzo San Michele to the west and Monte Cervialto to the east, separated from Accellica Sud (1,606 m) by the Varco Del Paradiso and the Ninno (1,538 m).

The summit ridge marks the watershed between the Picentino and Tusciano on the Salerno side and the Calore and Sabato on the Irpino side. Centuries ago this line determined the border between the Principato Ulteriore and the Principato Citeriore of the Kingdom of Naples. Today the ridge separates the comuni of Acerno, Giffoni Valle Piana and Montella.

The local names Céleca or Acéleca come from regional dialects and show the language of mountain communities in Campania. These traditional names are still used by people living in the surrounding villages.

Several marked trails run to the summit through forests with chestnut, beech, hornbeam, birch, lime, elm, and holm oak trees. Different routes offer varying levels of difficulty for hikers of all abilities.

The Ninno pass at 1,538 m once held a via ferrata installed by the Salerno branch of the Club Alpino Italiano to link the north and south summits across high rock and deep drops. After fatal accidents, the CAI removed it in 2018.
