To reach the start of this walk, take the access road to the hamlet of Campu, turning right off the D180 when coming from Bastia. At the entrance to the hamlet, there is a car park on the right.
(S/E) Take the narrow lane uphill and turn left at the patisserie; follow the narrow lane through the hamlet and continue along a dirt track which soon leads into the oak woodland.
(1) Carry on straight ahead and climb the hill to reach the San Salvatore Chapel (various names may be used depending on the website).
(2) Head towards the sea on the right, and follow the fairly wide, well-cleared path as it climbs gently.
(3) Walk past the isolated bell tower on the ridge and carry on, enjoying the lovely views through the gaps in the vegetation.
(4) Ignore the path on the right that leads back down to the hamlet of Campu, and continue slightly below the ridge towards the abandoned hamlet of Mata (views across the whole valley and out to sea, with the Island of Elba in the background; feel free to wander through the ruins, but take care).
(5) Then turn back and return to the previous junction.
(4) Take the path on the left to head back down towards the hamlet of Campu: a fairly steep descent with some quite stony sections. This is the least well-maintained part of the route. Return to the car park (S/E).
