It's tough climbing up here on a road bike, especially in winter... But an unforgettable and addictive experience... and then on beyond Ases there's still a good climb left, and then down (carefully) to Castellterçol

A very pleasant climb. Few cars, a cool, shady area. There are some rest areas that make the 8km climb manageable.

The road from Horta to Cerdanyola del Vallès connects the Vallès with the capital through a port with two different slopes, short and intense from Barcelona, and long and continuous from Cerdanyola. A good panoramic view from the Coll, where it crosses the Passeig de les aigues through a footbridge.

One of the most beautiful climbs through the Collserola Park. The views of the Vallés, with the surrounding mountains of La Mola, Tagamanent, Montseny and Montserrat are well worth it. It is a road in perfect condition without a hard shoulder and with some traffic, although not a lot. It is a classic among cycle tourists in Barcelona. The south side, the one in Barcelona, is very sunny and warm. The Cerdanyola del Vallés side is shaded and very humid, especially on cool winter days.

One of the two climbs that leave Terrassa and cross the Parc Natural de Sant Llorenç de Munt i l'Obac, thus connecting the Vallés Occidental region with the Bages region. Like the climb to Coll d'Estanalles, Coll de l'Obac is a very gentle climb, on a narrow, rough road, without a hard shoulder, very busy with cars on Sundays and public holidays, so you have to be careful, especially on the descent. The final stretch of the climb, the last 2 km, is by far the hardest, especially a very long straight that exceeds 7%. It is very pleasant to ride there first thing in the morning, with shade and the freshness of the forest. The views of Montserrat, the Bages plain and the Pyrenees line are well worth it... and a good photo.
