Hiking
Embark on a moderate 10.2-mile (16.5 km) ring tour through the Treja Valley Park, starting from the dramatic cliff-top village of Calcata. This hike, which takes around 4 hours and 33 minutes, leads you through varied terrain, including unpaved paths and sections carved into tuff rock. You will gain about 894 feet (272 metres) in elevation as you explore dense woodlands and follow the Treja River, culminating at the picturesque Monte Gelato Waterfalls where the river cascades over volcanic formations.
Good footwear is essential for this route, as some sections can be slippery, especially near streams. The path features ascents and descents, with parts running along the river, so be prepared for a mix of natural surfaces. While the research does not specify parking or public transport details, the trail is easily accessible for a day trip, located about an hour from Rome.
This trail offers a unique blend of natural beauty and rich history. The Monte Gelato Waterfalls are famous as a backdrop for numerous films and TV series, adding a cinematic touch to your journey. Beyond the natural wonders, you will encounter ancient Roman villa remains, a Faliscan necropolis, and a medieval water mill, all set against the charming backdrop of Calcata and Mazzano Romano villages.

Very windy day and what better idea than to slip into the shelter of the gorges of the Treja Valley! Beautiful, well-kept and signposted paths, a welcoming microcosm, accompanied by the sound of the Treja river and the Mola ditch which, playing in waterfalls and small rapids, amazed us between Calcata and Mazzano. With a few more kilometers we enjoyed a lot of silence even though it was Sunday 🥰
Suggestive excursion in the Treja valley, starting from the Monte Gelato waterfalls, skirting the Treja, passing through Mazzano and reaching Calcata Vecchia. Return on the same path with detour to the sanctuary. Lots of nature, relaxing murmur of the Treja waters, suggestive views and some ruins of past civilizations.
