From the Gilf gorge at the Passirio to Castel San Zeno: the Gilf promenade.
In 1880 the physician Hans Prünster started establishing the Gilf promenade, which bears the name of the Gilf gorge, the canyon of the Passirio between Monte San Zeno and Maia Alta. It is the sunny location at the rocky hillside of Monte San Zeno enabling sub tropic plants to grow at the foot of the Gruppo di Tessa mountain range, which belong to the Ötztal Alps.
The establishment of the Gilf promenade required several blasting operations and high walls had to be constructed. The promenade snakes up to Castel San Zeno and further on to the Torre Polveriera, a great course with a view on the centre of Merano, on Maia Alta and the savage floods of the Passirio river. At the end you reach the Torre Polveriera tower, where you can continue your walk along the Tappeiner promenade.
