Simbruini Mountains Regional Nature Park

Around Campo dell’Osso, woodland opens onto grassy clearings.

About

Around Campo dell’Osso, woodland opens onto grassy clearings. Above Camerata Nuova, a ruined village brings human history into the landscape. At Comunacque, attention turns to running water. The park covers roughly 30,000 hectares, with separate roads and trailheads. Choose one area and give it time. Enhance your adventure: download the Snappit app to identify the local species you encounter.

The regional park was established in 1983. Water links its natural history to Rome: the ancient Anio Vetus, Anio Novus, Marcio and Claudio aqueducts drew on the wider Aniene water system. A more intimate story waits above Camerata Nuova. The old settlement was destroyed by fire in 1859, and the walk between its ruins and the Madonna delle Grazie church makes the relationship between the present village and its predecessor tangible.

What to do here

Choose loop 664b for ruins and a viewpoint, or 673a for forest and open basins. Both are graded E: mountain hiking routes. ST1 at Comunacque is the shorter alternative. A booked visit to Cervara di Roma’s red-deer enclosure offers an educational option.

Seasonal info

Winter changes the activity completely. Snow can cover waymarks and hard ice can turn an ordinary path into technical terrain. On Monte Viglio the park specifically warns of cornices and avalanche danger. Do not treat a summer hiking grade as winter clearance; choose an appropriately qualified local guide when your own mountain skills do not cover the conditions.

Accessibility

No selected trail has verified step-free access. ST1 is short and graded T, but that does not certify wheelchair or pushchair suitability. For limited mobility, ask about a visitor centre or booked deer-area visit before choosing your destination.

Walks and routes

Camerata Nuova to Camerata Vecchia: loop 664b

Start at the Fontanile in Camerata Nuova and follow the published loop to Madonna delle Grazie and back past Camerata Vecchia. The church offers a natural pause before the old settlement’s ruins. The official circuit is 5.4 km, graded E, with 2 hours 10 minutes of published walking time. Allow around three to four hours if you want unhurried stops and a proper look at the village remains. Use the official route card rather than improvising a shortcut through the ruins.

A hiking circuit with climbing, not a level village stroll. Uneven ground and ruined masonry call for care; do not climb walls. No step-free certification is supplied.

Campo dell’Osso’s forest and meadow circuit: 673a

The 8.7 km E-grade loop starts and ends at Campo dell’Osso, linking Le Genzane, Campobuffone and Valle Maiura through beech woods and open grassy basins. Its published walking time is 3 hours 10 minutes; allow four to five hours with rests. This is the better choice when the landscape itself is the destination. The route uses parts of the cross-country-ski circuit and tracks, but also smaller paths, so keep track of junctions rather than following whichever broad track looks easiest.

A mountain hiking route, not a surfaced accessible loop. Forest cover does not make navigation automatic, especially in fog or when snow covers markings.

A short waterfall approach: ST1 at Comunacque

From Ponte di Comunacque, the park’s ST1 route reaches the Cascata di Comunacque, also called Cascata di Trevi. The published approach is 0.3 km and graded T, the tourist-walking category. The waterfall drops around ten metres near the meeting of the Simbrivio and Aniene. This is a useful smaller outing when a mountain circuit would be too much. Return along the approach and allow time to enjoy the water without getting close to an unsafe edge.

Short does not mean step-free. Wet riverbank ground can be slippery; supervise children closely and assess the path before committing.

For experienced hikers: Valle Granara to Monte Viglio, 696b

Route 696b climbs from Valle Granara through Valle Fura to the Cantari ridge and Monte Viglio. The park gives 4.7 km and 2 hours 30 minutes to the summit, graded EE for experienced hikers. Those are outward-route figures, not a complete there-and-back day. The steep climb and ridge finish need fitness, confident footing and a planned descent. Choose this as a dedicated mountain outing with a full-day margin, not as an extra after a picnic or museum visit.

An experienced-hiker route with steep terrain and a high ridge. It is unsuitable as the family or reduced-mobility option in this guide.

For experienced hikers: Valle Granara to Monte Viglio, 696b

A balanced two-day first visit

Give one day to Campo dell’Osso, adding Monte Livata’s centre if its opening fits. On the other, choose Camerata Vecchia for more walking or a booked Cervara deer visit. Save Comunacque for a Trevi-side day. Arrange driving and bookings separately.

Things to try

Join a guided day

The park’s current events programme includes guided and educational activities. For events run by the park, its 2026 notice requires a registration form, waiver and identity-document copy. Check the particular organiser, date, cost and cancellation arrangements before signing up.

Have an indoor plan ready

Use a confirmed opening at Jenne or Trevi’s visitor centre as your rainy-day alternative. Heavy rain can make the waterfall approach unsafe too. If the centres are shut, postpone rather than force an outdoor plan.

Wildlife and habitats

European beech

The beech is the tree that gives many of these walks their character. The park’s montane woods also contain mixed broadleaf communities, so notice the changes between closed canopy, woodland margins and grassland instead of expecting a single uniform forest.

Red deer

Red deer were released into the wild here in 2008–09. Their return is a conservation story, while the animals at Cervara’s educational enclosure are managed separately. Look from a distance, avoid approaching animals or young, and never feed them.

Roe deer

Roe deer are documented in the park’s montane fauna. A quiet walk may reveal signs rather than an animal. The former Trevi roe-deer enclosure is not a reliable viewing destination: the park says its animals were transferred elsewhere.

Wolf

Wolves belong to the park’s forest ecosystem, but a normal day walk should not be planned around seeing one. Enjoy learning about their habitat at the Monte Livata visitor centre, and leave baiting, calls and disturbance out of your visit.

Fire salamander

The park records fire salamanders in damp beech-forest environments. If you encounter one, watch without handling it or moving logs and stones. A species record is a reason to tread carefully, not an instruction to search a breeding site.

Rosalia longhorn beetle

This distinctive longhorn beetle is recorded in the park’s mountain fauna. Its presence adds an invertebrate dimension to a woodland visit. Leave insects, wood and bark undisturbed; there is no guaranteed sighting spot or season promised here.

Stories and discoveries

A landscape built around water

Rain and snow enter a limestone-and-dolomite mountain system, feeding springs as water travels underground. That helps explain why open karst basins, forest and abundant water can sit so close together. The wider Simbruini–Ernici water system also supplies communities beyond the park. Resist the temptation to treat a spring as a drinking-water tap unless its safety is explicitly confirmed.

A familiar-looking mountain plain

Camposecco has a second life in Italian cinema: the park identifies it with western films featuring Bud Spencer and Terence Hill. It is a different destination from the short Camerata Vecchia loop, so do not add it casually to route 664b without planning the extra walk.

When to visit

Spring: follow the thaw

Start lower when snow still lingers above the villages. Wet woodland and running water can be lovely, but postpone riverside walks after heavy rain. A snow-free road does not establish a snow-free trail.

Summer: shade, an early start and your own water

A beech-forest circuit gives more shelter from sun than an exposed summit. Start demanding walks early, allow for heat and thunderstorms, and carry water. At picnic sites, current fire restrictions take priority over older descriptions of barbecue facilities.

Autumn colour; winter mountain conditions

Autumn rewards a woodland-focused visit, with shorter daylight calling for an earlier turnaround. In winter, check road access and the day’s snow conditions before leaving. Choose a confirmed guided activity suited to your ability; Monte Viglio’s cornices and avalanche terrain are not a casual snowshoe extension.

Getting there and practical advice

Monte Livata visitor centre

The centre on Via della Bandita focuses on wolves. Its page lists daily opening from 09:30 to 16:30, but also asks visitors to verify hours and gives no validity period. Confirm before driving up specifically for the exhibition.

Jenne and Trevi: natural history indoors

Jenne’s centre at Via dei Prati 5 covers birds of prey and includes taxidermy dioramas; published hours are Monday–Friday, 08:00–13:00. Trevi’s Museo delle Piante on Via E. Germani combines plant interpretation, outdoor planting and a model of the park; its page lists Monday–Friday, 09:00–13:30. Check both for your date, especially holidays.

Book the deer area before you go

The red-deer area is at Prataglia, Cervara di Roma. Guided visits must be booked through [email protected]. The park advertises visits in busier periods and accepts requests for organised groups of at least ten. Ask about the next suitable visit, price, exact meeting point and access needs rather than assuming drop-in entry.

Picnics and practical supplies

The park lists picnic areas with tables and benches, and some have fire facilities. That is not a promise of toilets, drinking water, food sales or permission to light a fire. Buy supplies in your chosen gateway and carry them. For facility questions, call the park on +39 0774 827221; availability can differ sharply between a village and a mountain trailhead.

Choose the road for your side of the park

For the Subiaco side, the park directs drivers from the A24 at Mandela–Vicovaro onto the Tiburtina and Sublacense. Camerata Nuova is approached from the A24 Carsoli exit and the local road towards the village. From the south, the A1 Anagni–Fiuggi exit leads towards the Altipiani di Arcinazzo, Trevi nel Lazio and Filettino. Check current road notices, particularly for the Carsoli/Oricola interchange and snow-affected mountain approaches. Do not follow a navigation shortcut onto an unsigned forest track.

Public transport needs a complete return plan

The park’s general directions identify Cotral connections and railway gateways including Carsoli and Anagni. Use Cotral’s timetable search and journey planner for your actual date, with the final stop and last return written down. Local services and operators can change. No through bus to the selected mountain trailheads, Sunday frequency or guaranteed rail–bus connection is established here.

Ask about the entire visit

Ask specifically about distance from parking, gradients, steps, surfaces, seating and an accessible toilet. Confirm those details individually for the centre or deer visit you choose.

Good to know before you go

Take the park’s current route information and a suitable walking map; white-and-red waymarks do not remove the need to navigate.

Carry your own drinking water and food. A named spring or fountain on a map is no guarantee of safe, flowing water.

Wear walking shoes with grip, bring warm and waterproof layers, and leave your route and return plan with someone.

Keep dogs on a lead, take litter home and leave flowers and other plants where they grow.

Use authorised camping areas. For picnics, favour a cold meal and check current fire restrictions even where a barbecue point exists.

Confirm visitor-centre hours and guided visits directly; an online “open” label is not a booking.

Frequently asked questions

Pick 664b for the combination of a viewpoint and village ruins, or 673a for a longer woodland-and-meadow circuit. If you want only a short outdoor stop, ST1 is the smaller commitment. Choose by terrain, weather and ability as well as distance.
You can plan around public transport to a gateway town, but confirm the complete outward and return journey. A bus to Subiaco is not automatically a connection to Campo dell’Osso, and a station near the park is not a mountain trailhead.
The park supports wild wolves and deer, but sightings are never assured. The deer area at Cervara is a managed enclosure with separate booking arrangements. It should not be presented as a wild encounter.
No. The route catalogue is planning information, and the park itself calls its guidance indicative. Check recent notices and ask about your precise route, particularly after storms or snowfall. Respect a barrier or local closure even when an older online route remains visible.
The park’s August 2026 visitor notice says dogs must be on a lead and camping belongs in authorised areas. It also prohibits free fires and plant collecting. Ask about any additional rules for your chosen campsite, activity or visitor facility.
