Grigno: Caves, History and Nature

When planning a trip to Grigno, caves, prehistoric traces, cultural history and outdoor activities offer distinct areas of interest. Each destination has its own focus: from a path to a cave entrance to archaeological evidence, frescoes, winter trails and climbing. If you’re looking for a hotel, these themes can help you narrow down the focus of your stay.

Caves and prehistoric traces

The Grotta del Calgeron extends for 5 kilometres, making it one of the largest caves in the region. Its entrance can be reached in about 40 minutes via a fairly well-developed and frequently used path. For planning purposes, these are two different measures: the length refers to the cave, while the approximate time refers to the approach to its entrance.

The Grotta di Ernesto is another site associated with prehistoric times. Remains of a hearth found there confirm that the cave was used by a prehistoric human settlement. Together, the two caves illustrate different aspects: the Grotta del Calgeron is notable for its size and access, while the Grotta di Ernesto is notable for traces of earlier use.

Riparo Dalmeri is also associated with prehistoric research. Research there yielded the richest collection of painted stones found at prehistoric sites in Europe. If you plan to visit, the route from Grigno follows the Strada degli Altipiani. A permit must be obtained in advance from the Comune di Grigno to drive on this road.

Cultural history through art and modern history

The Calchèra de bòro in Grigno was included in the 2013 edition of the “Guida ai musei etnografici del Trentino” by the Museo degli Usi e Costumi della Gente Trentina in San Michele all’Adige. Its ethnographic focus adds a different perspective on cultural history to the prehistoric themes.

The Trincerone di Grigno formed the second line of Grigno’s wartime defensive barrier. The Chiesa di San Giacomo Maggiore contains frescoes by the painter Lucilio Grassi, dating from the first half of the 19th century. These places represent different historical contexts: the Trincerone is associated with the history of the First World War, while the frescoes date to the 19th century.

Trails and outdoor activities

In winter, the trails on the Marcesina plateau form a network of around 200 kilometres for cross-country skiing and snowshoeing. At the Riserva Naturale Provinciale Fontanazzo, visitors can walk a trail of about 4.3 kilometres. The scales are quite different: one is a seasonal network of trails, the other a single visitor trail. Canyoning is also possible on the Grigno River, and the Alla Curva climbing wall in Grigno is used for climbing.

There are several activities to choose from: winter trails on the plateau, a visitor trail in the nature reserve, canyoning on the river or climbing at the climbing wall. The information about Marcesina specifically refers to winter. When planning your trip, you can therefore distinguish the seasonal focus from the climbing and river activities mentioned, without treating the different offerings as the same kind of outing.

Getting there and planning your trip

Grigno can be reached via the SS 47 through the Valsugana valley and also by rail on the Trento–Venice line. If you’re planning to travel by train, check the current timetable. The Grigno–Passo Brocon route starts in Grigno and ends at Passo Brocon. An older route description says the starting point can be reached by train or via the Valsugana cycle path; check current transport and road conditions before relying on this information for your trip.

When looking for a hotel in Grigno, you can first decide which themes you want to shape your stay: caves and prehistoric traces, cultural history or outdoor activities. This lets you tailor your search to your planned activities and take the access and seasonal information above into account as you continue planning.
