Location and surroundings
Monte Cacume belongs to the Italian Peninsula > Anti-Apennines > Lazio Anti-Apennines > Lepini Mountains. It is in Italy, in the region of Lazio, and administratively in the municipality of Patrica, district of Frosinone. The mountain also lies near the boundary with Giuliano di Roma and the province of Latina.
The peak is part of a hilly limestone mountain landscape typical of the Lepini area, with ridges, slopes and nearby summits rising and falling over short distances. In the range it sits well below the highest summits, but it remains a clear local high point and a distinctive isolated mountain in the area.

The nearest higher peak is Monte Gemma, which rises to 1,457 m and lies 4.3 km to the northwest. Several other higher Lepini summits also cluster in that direction, so Monte Cacume sits on the lower flank of a more elevated ridge system rather than as an isolated high point above empty ground.
The view from the summit
Within 25 km, the highest summit is Monte Semprevisa at 1,536 m, about 11.6 km to the west. Other major peaks in view or within the same mountain group include Monte Malaina (1,482 m, 7.5 km NW), Monte Alto (1,416 m, 8.0 km NW), Monte Erdigheta (1,336 m, 10.0 km W) and Monte Lupone (1,378 m, 21.9 km W).
From a summit like Monte Cacume, the main skyline is therefore dominated by the higher Lepini chain to the west and northwest. The mountain is well placed for reading the structure of the range, with the tallest massifs gathered in a relatively compact area rather than spread far apart.
The range
Monte Cacume is part of the Lepini Mountains, whose highest peak is Monte Semprevisa at 1,536 m, about 12 km to the west. The range contains 97 named peaks, and Monte Cacume ranks 35th by elevation among them. That places it in the middle tier of the range rather than among its top summits.
The Lepini Mountains are part of the broader Lazio Anti-Apennines in central Italy. Monte Cacume’s position in this chain makes it a useful reference summit for the southern Lazio hills and mountains, with the higher core of the range lying a short distance away.
Climate and weather
Climate estimates from NASA POWER climate data for 2001–2020 suggest that the summit is mild for much of the year. The warmest month is July, at about 20 °C, while the coldest is January, at about 5 °C. Mean temperatures stay above freezing in every month at the summit. Around the mountain, annual precipitation is about 800 mm, with the wettest month in November at about 120 mm and the driest in July at about 25 mm.
In this part of Lazio, weather can change quickly with cloud, wind and rain moving across the ridges, especially in the cooler season. Summer heat is usually the main concern on exposed slopes, while winter and early spring can bring cold, wet ground and occasional snow on the higher parts of the range.
Best time to visit
Because summit temperatures stay above freezing all year, Monte Cacume can be visited in any season, but the most comfortable periods are usually the milder months of spring and autumn. The drier part of the year is around July, while November is the wettest month, so late spring and early autumn often offer a better balance of temperature and rainfall.
Summer can be warm on open slopes, so early starts are sensible. In winter, even at this moderate elevation, damp ground, cloud and colder winds can make the mountain feel less straightforward than the height alone suggests.
Nature and wildlife
The Lepini Mountains around Monte Cacume are part of a Mediterranean mountain landscape, with rocky slopes, scrub, grassland and patches of woodland on the lower and more sheltered ground. At this elevation, vegetation is usually a mix of hardy shrubs, grasses and scattered trees rather than dense high forest.
Wildlife in this part of Lazio commonly includes birds of prey, small mammals and other species adapted to dry hills and limestone terrain. Seasonal changes are important: spring brings more active plant growth, while summer can leave exposed slopes dry and sparse. The mountain’s isolated shape also makes it a good place to observe the transition between cultivated lowlands and upland terrain.
Guides and organised ascents
For a mountain like Monte Cacume, a certified guide is usually not essential for a straightforward day outing, but it can be useful if you want local route-finding help, winter conditions advice or a longer tour in the Lepini Mountains. In Italy, certified mountain guides belong to the Collegio Nazionale Guide Alpine Italiane, which is an IFMGA/UIAGM member. The national alpine club and mountaineering federation is the Club Alpino Italiano.
Examples of established guiding companies in Italy include Società Guide Alpine Courmayeur and Società Guide Alpine del Cervino. A guided outing usually depends on the length of the day, group size, whether equipment is needed and whether there are extra logistics such as hut nights. For local advice, visitors often also check with tourist offices in the area and with the CAI.
Safety and preparation
Monte Cacume is not a high alpine summit, but the terrain still calls for normal mountain preparation: sturdy footwear, water, sun protection and attention to weather changes. Exposed ridges can be hot and dry in summer, while wet limestone ground can be slippery after rain. In cooler months, wind and cloud can reduce visibility and make navigation less obvious than the elevation suggests.
For mountain rescue in Italy, call 112, the single European emergency number. Ask for Soccorso Alpino if you need mountain rescue. The older 118 number is still used in some regions, but 112 is the main number to use.
History and name
The mountain is known locally as a distinctive isolated summit in the Lepini area of Lazio. It is called Monte Cacume, and the topographic form Monte Caccume is also used. Some readers have linked the mountain with a possible mention in Dante Alighieri’s Purgatorio, in the fourth canto of the Divina Commedia, although this is a literary association rather than a confirmed historical fact.
The name appears in the mountain’s local and cartographic tradition, and the peak’s clear profile has made it a recognizable landmark in the Frosinone area for a long time.
Interesting facts
Monte Cacume ranks 35th among the 97 named peaks of the Lepini Mountains. Its nearest higher neighbour is Monte Gemma, 4.3 km to the northwest. The highest summit in the range, Monte Semprevisa, lies about 11.6 km to the west, so the mountain sits fairly close to the main high ground of the Lepini chain.
Another notable point is its border position near Giuliano di Roma and the province of Latina. That makes Monte Cacume a local landmark at the meeting point of different parts of southern Lazio, rather than a remote interior summit.
