In the small mountain village of Trin Digg, a village landscape designated as worthy of protection in the cantonal structure plan, visitable fortifications, and trails of very different character come together. You can explore the military history inside the rock, choose a challenging hike toward the Rhine Gorge, or cycle along a route toward Lake Crestasee. A bakehouse and a family-run holiday home also offer practical starting points for your stay; it is worth checking in advance whether baking sessions are taking place and what rooms are available.
Village Layout and Fortifications
Old stone houses and their barns are arranged in small groups around the village square under a special building regulation. The grouping of the houses and barns is itself a distinctive feature of the village landscape.
Above Trin Digg, you can visit the Sperre Trin fortification complex. Underground, 300 steps connect it to a second defensive system in the rock of Crap Pign. Guided tours include the rock fortifications in Crap Sogn Barcazi and Crap Pign, which are connected by a stairway system. The program also includes exterior views of the Porclas Nord, West, and Strasse bunkers, as well as the kitchen of the Fortress Guard Corps (FWK). Check the museum’s information for specific visiting times.
In Crap Sogn Barcazi, a rocky outcrop with castle ruins between Trin and Trin Mulin, there is a fortification built during the Second World War that can also be visited.
Hiking Between the Village and the Rhine Gorge
Ruinaulta Sut (656.1) is the challenging option: the hike begins in the small mountain village of Trin Digg and descends via Ransun into the Rhine Gorge, ending at Versam/Safien railway station. The route leads to the Islabord viewpoint, with views across the Rhine Gorge, and crosses a suspension bridge that offers a view of the Rhine.
Another option is the Trin Porclis circular trail. It loops around Bot Fiena toward Trin Digg, then returns to Trin Porclis through the old village. This leisurely circular walk through forests, hedgerows, and wide-open fields at the foot of Crap Sogn Parcazi offers a different experience from the challenging Ruinaulta Sut.
The Trin Digg–Crestasee route passes the Sperre Trin fortress museum in Trin Digg, followed by a short climb to Lake Crestasee. This lets you start the hike with a view of the fortification before continuing to the lake.
Cycling Routes and Stages
The Trin Digg–Crestasee route runs through the Flims Forest and along the Felsbach Gorge, returning to Flims on unpaved roads. It is rated an easy route, 22 kilometres long, and is also described as an e-bike route for beginners and families with bicycle trailers for children. Check the latest conditions before setting out.
Another named stage is Via Son Giachen: Trin-Digg–Falera. Shortly after leaving Trin Digg, it crosses Val Pintrun. The stage also passes through the Flims/Laax landslide area and offers views down into the Vorderrhein Gorge. Check the current route status before setting out.
Bakehouse, Drinking Water, and Accommodation
A regional description from winter 2025/26 reports that Erica Rada runs a bakehouse on Via La Crusch in Trin-Digg, equipped with a large wood-fired oven. Visitors could bring their own dough, ideally around 10 a.m. Check locally whether baking is currently taking place and what dates are available.
The Via Digg water fountain provides official drinking water for refilling bottles. It can be reached by train, car, on foot, or by bicycle. If conditions change, check availability locally.
Trin Digg has a family-run, self-catering holiday home with single, double, and shared rooms for a total of 33 people. Room availability and capacity may change; check these details before booking.
