Monte Biaena, Mountain summit in Trentino, Italy

Monte Biaena is a 1622-meter mountain in the Garda Mountains, west of Rovereto and east of the Gresta Valley. Its north slope carries dense conifer woods and beech coppice, while the south and east sides drop in tufaceous and limestone cliffs cut by steep gullies. The summit holds a cross, a chapel, the Val di Gresta SAT hut and Austro-Hungarian trenches.

During World War I, the summit served as an Austro-Hungarian military position with trenches and artillery installations. The occupiers also constructed a water collection system on the western slope to supply their forces.

Vineyards at the mountain's base grow Marzemino grapes following regional winemaking practices that have been passed down through generations. This grape variety shapes the landscape and remains central to local identity.

The main route from Passo Bordala takes about 50 minutes and starts at 1253 meters elevation with clearly marked trails. Good hiking boots and plenty of water are recommended, especially on warmer days.

The Grotta di Stenone on the mountain's slopes maintains ice formations year-round, even during summer months when temperatures typically warm. This ice cave was documented as early as 1671 and draws visitors curious about this unusual natural phenomenon.
