Fondo: Trails along the Rio Sass and a water heritage

Explore Fondo on foot, by bike and through its cultural sites. For planning your trip, consider the specific differences: one trail connects the historic center with Lago Smeraldo, while another loops around the lake; cycling options include a marked circuit and a guided e-bike tour. You can decide which kind of outing you’d like to make a feature of your stay.

Walking between Fondo and Lago Smeraldo

The Rio Sass canyon cuts through the town of Fondo. The Passeggiata al burrone connects the historic center with Lago Smeraldo and follows the Rio Sass stream. It is an easy family trail featuring sheer rock walls, waterfalls, suspension bridges and old mills. Its route links two distinct points—the town center and the lake—while also following the stream. There is also a loop trail around Lago Smeraldo that is suitable for strollers. The practical difference is that the Passeggiata connects the center and the lake, while the other trail forms a loop around the lake.

Cycling and winter routes

The marked Alta Val di Non cycle route is an approximately 40-kilometer loop that includes Fondo. The western side is worth noting when considering the route’s profile: it is mostly flat there. A guided e-bike tour starts in Fondo and follows the cycle route through forests, meadows and villages. These are two different options: a marked loop with a known total length, and a guided tour with a described landscape along the way. Dates and availability for the listed 2026 departures may change; check these details before making plans.

The Ciaspolada is also part of the region’s winter history. In the early 1990s, the snowshoe race was moved from Tret to the Pradiei meadows between Fondo and Romeno. Two editions took place entirely in the town of Fondo. The current course may vary depending on snow conditions. A winter route in the wider region partly follows the race course; this route is seasonal. The historic venues and the seasonal route are therefore distinct points to consider when planning a winter visit.

Water, technology and local history

Water is also a theme at several cultural sites. The Museo La Casa dell’Acqua features interactive exhibits, including a scale model, a 4K film, stop-motion videos and a display explaining how a hydroelectric power plant works. A guided tour of the museum also includes a visit to the Mulino Bertagnolli. There, water from the aqueduct still turns the wheel; in the past, the wheel drove the millstones. Fondo’s astronomical water clock tells the time and consists of two interconnected mechanisms powered by water. The museum, mill and clock each show a different connection between water and technology.

Fondo’s historic center has painted façades dating from the 14th to the 16th century. The Church of Santa Lucia contains an extensive fresco cycle dated to 1380–1399. You can also see several frescoes in Fondo dedicated to Saint James of Compostela. Together with the technical exhibits, these sites offer a picture of the town that includes both historic art and the local use of water.

Local products and dining

The Malga di Fondo produces mountain cheese, butter, yogurt and ricotta. During its operating months, it serves lunch and dinner by prior reservation. Its seasonal opening is an important part of planning: check opening hours directly with the operators and book in advance. This lets you include a meal as a separate part of your stay, without confusing it with trails or cultural attractions described as available year-round.
