The mountain you see from the Janiculum on a clear day: a limestone summit of 1,271 metres north-east of the city, reached through oak woods and over a high karst meadow. From the top, Rome lies spread across the plain with the sea glinting beyond. The real hike within an hour of the city.
Monte Gennaro, properly Monte Zappi, is the best-known peak of the Monti Lucretili, a limestone range protected as a regional park. Horace had his Sabine farm in these hills.
The classic ascent starts from Palombara Sabina, a hill town crowned by the Savelli castle. Paths climb steeply through holm oak and downy oak woods, then emerge onto the Pratone, a broad karst plateau at about 1,000 metres, grazed by horses and cattle and dotted with sinkholes. The final climb leads up a grassy ridge to the summit.
The view is the reward: the Tiber valley and the whole Roman Campagna, the city itself, the Alban Hills, and on clear winter days the Tyrrhenian Sea. To the east, range after range of the Apennines. This is a proper mountain walk, with steep, stony sections and no water on the way.
Park trails are marked with the CAI's red and white paint. Carry a map: junctions are many.
Approximate profile. Solid: up; dashed: down by a different path.
From the trailhead above Palombara Sabina, paths climb steeply through oak woods on the mountain's western flank.
Emerge onto the wide karst plateau at around 1,000 metres, with grazing animals, sinkholes and the summit ridge ahead.
A last steep climb up the grassy ridge leads to the top and its view of Rome, the Campagna and, on clear days, the sea.
Descend on a different trail to make a loop back to the start, and finish in Palombara with a look at the castle.



Palombara Sabina is about an hour north-east of central Rome. Drive up towards the trailheads above the town.
Cotral buses run from Rome's Ponte Mammolo metro station to Palombara. Check return times carefully; the last bus can be early.
Cloud can roll in over the plateau, hiding the paths. In poor visibility, turn back. In summer, start very early to avoid the heat.
