Sources differ: E (CAI) (Parco Naturale Regionale Monti Aurunci)

The park's graded-E line to the roof of the Aurunci: an old mule track from a cistern on the Piana di Fraile (about 820 m) up the wooded Fosso di Canale to the Fontana di Canale spring, a short steep rocky step to Sella di Fossa Juanna, then beech wood and open karst to the antenna-topped 1,533 m summit. 5.7 km, 715 m, about 3 hours up.

The start is a cistern beside the dirt road that crosses the Piana di Fraile, in the municipality of Esperia, reached by car from Maranola (Formia) over the Forcella di Fraile (985 m). CAI path 915 follows an old mule track across the plain to the mouth of the Canale, where path 915b branches right towards Rifugio Pornito. Cross a ditch, traverse into the wooded Fosso di Canale and climb the gully to the Fontana di Canale (about 1,276 m), described by the park as the highest perennial spring in the Aurunci. From the left side of the clearing at the spring, white-red marks lead up a short, steep rocky section to the Sella di Fossa Juanna, beside the large sinkhole of the same name. Turn right through beech and conifer woodland; above the trees the final slope is climbed by sight over karst ground to the summit, which carries a small solar-powered transmitter station with tall antennas and a tiny helipad. The views reach Vesuvius, Monte Cairo and the Gulf of Gaeta. Descend the same way (the park gives 3 hours up for 5.7 km and 715 m). From the east, the CAI 913 and 968 paths climb from Spigno Saturnia and the Ciaia di Biviano (890 m) via Sella della Valle; they are graded EE because of the length and height gain, and the Cammino degli Aurunci links the summit with Monte Sant'Angelo and the Redentore.

Overview

The highest summit of the Aurunci Mountains (1,531 m) in southern Lazio, a karst dome rising 1,500 m above the Gulf of Gaeta. Waymarked CAI paths climb through beech wood from the Piana di Fraile or from Spigno Saturnia to a summit topped by small antennas, with views to Vesuvius and Monte Cairo.

Monte Petrella is the high point of the Aurunci, the limestone mountains of the Lazio Anti-Apennine between the Liri valley and the Tyrrhenian coast at Formia and Gaeta. It lies in the municipality of Spigno Saturnia, close to the borders of Esperia, between Monte Cavecce to the north-east, Monte Coculo to the north-west and Monte Campetelle to the south, inside the Monti Aurunci Regional Nature Park. With about 1,370 m of prominence it stands well clear of its surroundings.

The massif is one of the richest karst and caving areas in Lazio: the summit plateau and the north-east ridge are pitted with sinkholes such as the Fossa Juanna, and abysses down to 315 m deep (Abisso Shish Mahal) have been explored. The summit area is a proposed Site of Community Importance (IT6040026). The top itself is open and stony, with a small solar-powered transmitter station and a helipad.

The usual approaches are from the west, by CAI path 915 from the Piana di Fraile above Maranola (graded E, about 3 hours), and from the east, by CAI 913 or 968 from Spigno Saturnia and the Ciaia di Biviano (graded EE for length and height gain). Longer days link the summit with Monte Sant'Angelo, Monte Altino and the Redentore on the Cammino degli Aurunci.

Climbing Notes

A straightforward but full half-day for a fit walker: about 715 m of ascent from the Piana di Fraile, or over 1,300 m from Spigno Saturnia on the eastern paths, which are long and steep. The ground is mule track, woodland path and finally open karst, where the line is followed by sight; watch the paint marks on trees and carry a map or GPS track in cloud.

The park recommends March to October. Spring and autumn are best; summer can be hot on the lower slopes, and winter brings occasional snow and ice on the upper mountain. The only reliable water is the Fontana di Canale on the Fraile route.
