산트 비센치 드 몬탈트‬에서 가장 멋진 ‪4‬개의 산길

Coll de Orrius is also known as Coll de Sant Bertomeu.

It is one of the many climbs that cross the coastal mountain range of the province of Barcelona, connecting in this case the towns of Argentona with Roca del Vallés. It is a port parallel to Coll de Papers, although this is much harder. The Argentona side is longer and with less slope than the Roca del Vallés. The Argentona side is 6.5 km with an average gradient of 4.5%. There is a rest with a descent in the middle area of the port, the second section being harder than the first. The Roca del Vallés side is barely 4 km with a very constant average gradient of 7%. The views of the valleys, the coast and Montseny from the top of the port are very cool and well worth it.

Collsacreu is a small port that allows you to travel from the interior to the coast. On this side, the real difficulty is in the last 2 km, where there is some 8% ramp. Road with a lot of traffic, but wide and with very good asphalt. It is worth being very attentive.

In my experience, it gets harder if you start from La Roca del Vallés. It does not have particularly complicated slopes, but the ascent can become somewhat tedious. I advise going slowly and taking a steady pace to the top, where you can pull over to the side of the road and enjoy the beautiful views. The descent from the top of Coll to Òrrius (I recommend extending it to Mataró / Vilassar de Mar) translates into a few minutes of adrenaline and speed. Of course, be careful with some curves, which are somewhat closed and force you to slow down. If you finally continue descending, via Argentona, you will end up on the Costa del Maresme, very close to the train tracks and the CostaMar apartment complex. In short, a good challenge for cyclists of any level, with the reward of a dizzying descent and a varied and attractive landscape. Recommended.

9% section Located between the exit roundabout of the C-35 - Llinars and approx 300m up the road towards dosrius. Then the climb continues calm and the descent is the same.

Road that connects the municipalities of Dosrius and LLinars, from different regions. In one section there is a slope of more than 9%

It is a hill with views of the entire Vallés, little traffic and a crossing point between MTB, gravel cyclists and road cyclists. The track on the right looking towards Òrrius reaches the hermitage of Sant Bartomeu, very quiet. The descent is cool in both directions, although in the winter season you have to be careful on some curves that are very wet.

Watch out on the small descent in the middle. It's tempting to go fast, but it has two corners with low visibility 😆
