The route begins next to the Cooperative building (WP1). As far as the Coll Major it is waymarked as a GR (in red and white paint). Take the Horta path, paved and enclosed between stone walls, leading to the river Cortiella. Cross the river (WP2) and go uphill along the farm track. Very soon you come to the old "camí ral" or road from Porrera to Falset which sets off straight ahead (WP3).
A route over the flat areas and slopes of the shady side of the shoulder on which the village is perched.
The soil is deep here thanks to erosion and sedimentation of the red sandstone of Albarca and lutitic materials with gypsum. The heads of the stream beds that start here reveal outcrops of limestone.
Flora route
Height difference: 100 m; starts at 780, goes down to 720 and climbs to 820 m.
A route on the sunny hillsides on the lower slopes of the Montsant massif. Beneath the towering cliffs that loom over the stream bed coming down from the Pregona spring, material resulting from erosion has built up. The stream beds that now only carry water from time to time have cut into the different geological strata and at the same time carried away much of the sediment.
Flora route
Scrub and vineyards Cartoixa d’Scala Dei
Height difference: 200 m, from 450 to 650 m.
Route in the area known as Les Obagues, at the foot of the cliffs of the same name that overlooks the whole area where the plain around Ulldemolins meets the Montsant massif. It goes from relatively flat places to approach the slopes that lead to the foot of the cliffs on the shady side of Montsant.
Flora route
Habitat
Pines and oaks at Fontalba
Ulldemolins
Height difference: 50 m. From 690 to 740 m.
A route on slate hillsides, punctuated with red sandstone and limestone, beneath the cliffs of Els Montalts. This is a hot, dry place in summer, with soils that allow rainfall to drain away quickly and make life very hard for plants.
Flora route: Scrub at Els Rogerets
La Vilella Baixa
Height difference: 100 m, from 240 to 340 m.
Starting point: bend in the T-702 road close to the Cantó del Barrot, at the top of the village. Return to the same place.
