From Borgo Sa Duchessa to Riu Tinnì (D-329)

WARNING: The route and signs are undergoing checks and maintenance.

The trail starts from the Sa Duchessa mining area leading to the bank of the Riu Tinnì stream through a dirt road, deep into the mountain. You will walk along mule tracks in the forest, passing by the remains of the Sa Duchessa mine works, admiring an impressive chute once used to transport the extracted material. The trail ends at the old municipal road to the Tinnì mine, which is also within easy reach.
