The route starts in “Surroca de Baix”, a small neighbourhood in the municipality of Ogassa. It is a former mining colony founded in 1870 to provide services and housing for the employees who worked in the coal mines in the area. From the R36 sign Colònia minera de Surroca - Plaça Dolça head towards “Sant Martí d'Ogassa”. Pass along “Mina Dolça”, situated across the stream, and climb some stairs up to a coal factory. After a short but steep climb you arrive at “Ca l'Ermangol”, at this point leave the Itinerànnia marks that go upwards. Continue straight ahead along a wide and flat path, an old wagons road, where you can see the old cable station used to lift down the coal from the highest areas of the basin.
You will arrive at the “Plaça del Taller” square where at the end of an inclined plain you will see a spring and the Pinter mine. Walk up the path, while enjoying the “Torrent de la Font Gran” waterfalls until you arrive at the same source of the stream. To continue with the route you must walk up to the “Prat Pinter” colony, where there is a church, a school and houses of the former miners. Here, beside a fountain, you can see again the Itinerànnia route marks.
Walk up the main road following the marks, and then take a wide track until you get to a farm's gate standing in your way. You have to go left climbing up a trail that ends up becoming a little path until you get to the main road once again. From now on, follow this road to the right. You will arrive at “Sant Martí de Surroca”, a Romanesque church from the 11th century, and worth a visit. Continue along the same road, ignoring any detour, until you arrive at the R38 sign Coll de la Creu.
Go towards Ogassa through “Roqueters”, carefully following the marks that will lead you to a trodden path while surrounding the hill of “La Caritat” through the left. Stay on the path passing along a reddish rocky area with little vegetation until you arrive at the wide “Coll de Sabè” pass. Pay attention to the marks and head right going deeper into the shady beech forest of Assuca. The pleasant and relatively flat trail will lead you to a small pass allowing you to cross over to the sunny side of the mountain. As you rapidly descent towards the “Roqueters” farmhouse a magnificent view of the southern mountains opens up right in front of you.
Once you are at the R37 sign Roqueters keep walking towards Ogassa through a wide track. You have to cross a pass and go down through a little path amid a forest until you arrive at “Can Guillem”. Keep walking on a paved trail, always descending, and just before crossing the Malatosca stream, you find the “Can Sisquet” fountain and the Tontos mine. Finally you arrive at Ogassa, where you return to the “Plaça Dolça”, starting and end of the route.
