Lago di Fiastra and Lame Rosse Day Trip
A Lago di Fiastra and Lame Rosse day trip works well because the two places are linked by a trail that starts at the dam. The lake lies in the municipality of Fiastra, in the province of Macerata, inside the Sibillini National Park in the Sibillini Mountains. The Lame Rosse sit higher up, in the Fiastrone valley, and can be reached only on foot. The trail (E2, CAI-marked as 335) is between 6 and 7 km round trip and takes about 2 and a half hours, stops included. That leaves time for the lake before or after the walk.
The lake is artificial: the dam on the Fiastrone river, 86 m high and 360 m long, was built in the 1950s and created the largest hydroelectric reservoir in the Marche region. Today the reservoir has a beach with facilities, canoe and pedal boat rentals and a flat walk along the shore. The Lame Rosse are pinnacles and towers of gravel, clay and silt shaped by erosion, often called the "canyon of the Marche". Their color ranges from reddish to ocher depending on the light.
Lago di Fiastra and Lame Rosse day trip: what to know
The trail to the Lame Rosse. The starting point is the dam, in the hamlet of San Lorenzo al Lago. The route crosses the dam on foot, passes through a small tunnel and joins trail 335. The first stretch is a dirt road that becomes a footpath in the shade of a holm oak wood. For the first kilometers the Lame Rosse are out of sight: they appear only in the final section.
The route is graded E (hiking difficulty) and is an out-and-back, returning along the same track. The elevation gain is about 300 m and is concentrated almost entirely in the final ravine. Along the way there is a turnoff toward the Gole del Fiastrone gorge, which should be ignored. Once in the gravel gully, signs point uphill to the left. The last stretch is short. It is steep and on loose gravel, where slipping is easy, and it is the most demanding part of the hike.
Rules of conduct at the base of the Lame. At the base of the formations, visitors are advised not to approach the walls, enter the small gravel canyons or climb into the neighboring gullies: there is a danger of rockfalls and landslides, and every passage speeds up erosion. The same applies to the descent, which should not be rushed. Collapses have been recorded in the upper parts of the Lame Rosse in the past. With ordinance no. 39 of July 28, 2022, the Comune di Fiastra regulated the use of the trails of the Lame Rosse, the Grotta dei Frati cave and the Gole del Fiastrone. Access to the Gole del Fiastrone is forbidden. Access may change over time: before setting out, it is wise to check the notices of the Comune di Fiastra and the Park. In 2021 the Comune di Fiastra had regulated entry to the Lame Rosse by ordinance, with the possibility of paid, limited-number access, but on July 6, 2021 it revoked it and access became free again.
The lake. The lake suits a relaxed day. San Lorenzo al Lago has a beach with a bar, showers and umbrella and lounger rental. Canoes, kayaks, pedal boats and small electric boats are available to rent, and there is an adventure park with routes over the water. The lake bottom is rocky rather than sandy, and some recommend water shoes.
For a walk with no elevation gain there is the Sentiero Natura (nature trail). It starts from the beach area, follows the right-hand side of the lake and runs almost to the dam, for about 3 km. It can be done on foot or by bike, and also with a stroller. On the dam itself it is possible to stop and look at the lake on one side and the Sibillini on the other.
How to plan the day. The Lame Rosse take about 2-3 hours, and the rest depends on the walking pace. The lake can be visited before or after the hike. It is best to keep the walk to the cooler hours and spend the rest of the day at the lake. To reach the area, the page on how to get to the Sibillini Mountains sums up the access roads. Those who want to fit the outing into a longer trip can start from the Sibillini Mountains day trip itinerary.
When to go on a Lago di Fiastra and Lame Rosse day trip
For swimming and water activities the recommended period is July and August, preferably in the morning. The water stays cold even in summer and the bottom drops quickly a short distance from the shore. Swimming is allowed only at the marked spots. Since the lake is a hydroelectric reservoir, at certain times the level is lowered for maintenance and its appearance changes a lot: it is worth checking beforehand, especially for a swim. For more seasonal tips, see the Sibillini Mountains in summer and the Sibillini Mountains in fall.
For walking to the Lame Rosse late September is a good time. It is less hot, there are fewer people and the trail is easier to follow. The woods give shade along most of the route, but the last stretch on the scree is exposed to the sun. The red of the formations looks especially intense at sunset.
The busiest days are in summer and, in the fall, weekends and public holidays. On high-season holidays the trail is very crowded, and the parking areas near the dam fill up too. If possible, choose a weekday or arrive early. For an overview of the whole year, see the page on the best time to visit the Sibillini Mountains.
Lago di Fiastra and Lame Rosse day trip: practical tips
Where to park. Near the dam there are few roadside spaces and no-parking signs need attention. A short distance from the dam there is a lot set aside for parking, also with limited spaces. If it is full, the previous parking lot is an option, a little farther from the trailhead.
What to bring. There are no water refill points along the trail: carry a sufficient supply. In hot periods a hat and sunscreen are useful. Hiking shoes with good grip help on the gravel section, and those wearing light footwear risk slipping. Check the weather before setting out.
With children and dogs. The route is considered suitable for anyone with a minimum of fitness, children included, and many families do it with young kids. The exception is the final gully, to be tackled with care. For ideas better suited to little ones, see the Sibillini Mountains with kids. The trail is listed as accessible to dogs, but checking with the Park Authority is recommended; the rules are on the page about the Sibillini Mountains with your dog.
More ideas in the area. Those with more time can look at the area on the Monti Sibillini map. Other hikes also start from the same area, such as the one to the Grotta dei Frati, but access conditions must be checked case by case (see above).
