In the village of Bavella, take the GR20 (marked in red and white) to the right of the hostel.
Walk in the pine and fern forest in the footsteps of the GR20 for 15 minutes. Then take a small descent to a stream. You will find a forest track before a fork. 50 m later, take the left lane and cross the creek. 5 min after the creek, start the climb and 45 min after you will reach the Foce Finosa pass.
