Hiking to Cala Biriala
Starting point: Località “Olobitzi”
Description: once you reach the Golgo plateau, follow the directions to Cala Sisine (the dirt road turns right before getting to the small white country church of San Pietro). First, you go near Nuraghe Ordoguri (on your left), then you go past the sign to the Ispuligidenie footpath, until you reach “Olobitzi” area, around 16 km from Baunei.
From the wide clearing, where you can park your car, you have to take the visible small track uphill on your right, direction north (a first detour on your left will take you to a recently renovated sheepfold instead). After a while, you get to another detour, on your left, taking you to Serra Ovra (369 m a.s.l.). You must go straight, just following the path, running along “Scala Oggiastru” ridge, until you get to a panoramic rock overlooking the sea and the Urele cliffs. Now the track runs downhill, getting to another fork: now you are at 330 m a.s.l.; when the mule track turns right, you will immediately see on your left the small trail taking you upward to “Coile Piddi”, in about 40 minutes.
Now you just walk on the track downward, which is still visible in this first part of the excursion; before you reach an amazing lookout, you will be already able to see the Cala Biriala and its characteristic sandstone arch.
This high lookout is situated just before the first obstacle to be taken over, that is to say a passage, protected by a steel cable, which takes to an exposed stairway. After a small leap, you will end up on a beautiful rock amphitheatre. From now on, you will walk steeply downward, the trail being no better visible as in the first stretch, until on your left you will get to the second difficult obstacle.
A rock wall, suspended in space, is provided with a metal ladder, thanks to which you will be able to overcome a leap of about 5 m; and then, after climbing downwards on the rocks (be extremely careful!), you will finally reach the wood below. You walk downhill direction NE; at about 100 m after the metal ladder, you must pay attention because in the wood the trail is not always visible. Keep going direction N, maintaining your left, until you reach some coal yards, and finally the deep blue of the sea.
