The Reserve is part of the Appenine range. It covers
 30,000 hectares and includes seven localities,
from Trevi and Filettino along the higher reaches of the River Aniene, and includes Vallepietra, Jenne, Subiaco and also Cervara di Roma and Camerata Nuova towards the Abruzzo. The whole area is very thinly populated. The Simbruini Mountains are a redoubtable limestone chain between Lazio and
the Abruzzo, rising to the peaks of Mt Autore (1853 m),
Mt Tarino (1961 m), Mt Cotento (2014 m) and
 Mt Viglio (2156 m).

The Park features many interesting geological aspects, including gorges and caves. These include the
“Ice Well” at Camposecco in Camerata Nuova,
 and the caves of
Inferniglio,
near Jenne,
Simbrivio,
at Vallepietra, and Pertuso, near Filettino.
 

At a height of 1200 to 1800
metres,
there are splendid forests of beech,
mountain ash, yew and maple.
Lower down, there are woods of oak,
flowering ash, and hazel.
In early summer there are magnificent
displays of violets, narcissus and
many kinds of wild orchid.
