The highlights of the tour? The trenches and the military cemetery at Passo Nota, the botanic and natural heritage of Tremalzo, the bird ringing centre at Casèt, the view over Lake Ledro and Lake Garda and the landscapes in the mountains and on the valley floor. 

Author’s recommendation

Why not make a stop and learn something more about Valle di Ledro? The Pile-Dwelling Museum along the shores of Lake Ledro, the Monsignor Ferrari Visitor Centre in Tremalzo, the War Museum in Bezzecca and the Foletto Apothecary Museum in Pieve are well worth a detour. User
