North of the town of Bolotana, along the provincial road SP17 you come to a vast forest called Ortachis. In this place of particular panoramic and naturalistic importance, we can also find a well-equipped municipal park known as Parco Pabude.
This forest area preserves traces of the last of the island’s ‘prehistoric’ forests with magnificent and immense specimens dating back centuries. The area is also well known for its archaeological site of the same name.
Its flora focuses around the presence of holm oaks, downy oaks, maple trees and English Yew, interspersed with patches of thick undergrowth shrub or pastures.
North of the forest, in Mularza Noa, you can admire an unusual waterfall known as Cascata Ortachis or Cascata di Mularza Noa. The waterfall has a drop of around 6 metres and its waters flow from the Riu Biralotta river, whose source starts at the Nuraghe Ortachis, just 700 metres further upstream.
The river flows on the plateau of volcanic origin, made up of stacks of welded tuff and other pyroclastic deposits. Some of the faults were caused by geo-morphological gaps giving rise to the precipice where the river’s waters flow into.
The forest can be reached easily from the town along the provincial road SP17 in the direction of Badde Salighes, another well-known forest not too far away.
