Driving the winding T-301 road through Coll de Som in Tarragona
Coll de Som is a scenic mountain pass at an elevation of 189m (620ft) above sea level, located in the province of Tarragona, Catalonia. While its altitude might seem modest compared to Pyrenean peaks, it is a legendary route within the Terres de l'Ebre region, famous for its technical layout and its role as a natural balcony over the final stretch of the Ebro River.
The pass crosses the southern end of the Serra de Cardó, a rugged limestone mountain range that defines the landscape of the area. Historically, this route has been the natural link between the riverside villages of the Baix Ebre and the inland towns of the Ribera d'Ebre. The environment is a perfect example of the Mediterranean dry forest, where pine trees and aromatic shrubs cling to the white rocky cliffs that flank the road, offering a sharp contrast with the lush green valley floor below.

How technical is the drive over Coll de Som?
The road over the pass, the T-301, spans 12 km (7.45 miles) and connects the municipalities of Tivenys and Benifallet. What makes this drive a favorite for enthusiasts is its relentless winding nature. In just a few kilometers of ascent and descent, the road features 15 sharp hairpin turns. The asphalt is in excellent condition and includes modern safety barriers, though the road remains narrow as it hugs the mountainside. The constant change in direction and the well-banked curves provide a dynamic experience that tests the agility of any vehicle, making it a "must-drive" for local motorcyclists and road cyclists.
What are the best viewpoints on the T-301?
The main draw of Coll de Som, beyond the driving pleasure, is the unbeatable panoramic views of the Ebro valley. As you climb, the river reveals its majestic meanders, which are particularly stunning during sunset. From the summit, you have a clear sightline of the Ports de Tortosa-Beseit mountain range to the west and, on very clear days, the distant silhouette of the Ebro Delta to the south. Several small pull-off areas allow drivers to stop safely and admire the limestone formations of the Serra de Cardó. Its proximity to the Coves Meravelles in Benifallet and the historic riverside paths makes it an essential segment of any road trip through southern Catalonia.
Is Coll de Som safe for all vehicles?
Despite the high number of hairpins, the T-301 is a safe, fully paved road suitable for all types of passenger cars. However, caution is advised due to the narrow sections where the road is carved directly into the rock. During the weekends, the pass is very popular with groups of cyclists, so motorists should be mindful of sharing the road. In summer, temperatures in the valley can exceed 35°C, but the road remains open year-round, as snow is virtually unheard of at this altitude. The descent towards Benifallet is particularly scenic but requires good brake control to manage the 15 hairpins safely while enjoying the Mediterranean scenery.
