The Transllena route runs through the municipalities of La Pobla de Cérvoles and El Vilosell. It goes up to the Sierra de la Llena, from where you can enjoy views of the Montsant mountain range, much of the Garrigues region and Conca de Barberà and, on clear days, even the Pyrenees. It is a circular route, it has its beginning in La Pobla de Cérvoles, with a level of average difficulty.
Els Vilars was an impregnable fortress from the s. VIII to the s. IV BC, inhabited for 400 years. It is unique in the Catalan Iberian world. Its defensive characteristics made it impregnable, and its historical and archeological value made it worthy of the declaration of Cultural Asset of National Interest in 1998.
Its origin goes back to the year 1194, when the king Alfonso II the Cast gave the earth in which later the Carthusian monastery was raised. The s. XVIII had three cloisters and up to 30 cells. It was a center of religious interest and had an important pictorial school headed by Joaquín Juncosa. The current name of the region, Priorat, comes from the existence of this monastery. In 1835 the community left the monastery under the law of confiscation. At present, the visit allows to contemplate the baroque portal of the Virgin, the church and a reconstructed cell that has the furniture and utensils typical of the Carthusian monastic life. It is located at the foot of the Sierra de Montsant, a place of great scenic beauty.
