Parking is difficult in the area after 10:00. The area is beautiful and has great views. You can take a practically flat route (Collformic to the ruins of El Café, but it's not circular), a more challenging one like Matagalls. And many more!

It is located between the Coll de Gomara and the Alto de Santa Fe del Montseny. It is a beautiful area with very wide panoramic views of the province of Girona. On its southern slope, there is hardly any difficulty since it is reached by descending from the top of Santa Fe and with a short final climb of 1 km. On the other hand, on its northern slope it is very hard, with almost 2.5 km at 7.7% on average, and a first initial straight when taking a detour at the Coll de Gomara of 11%.

The port of Collformic on its southern slope is spectacular. It is a long climb, with a couple of really demanding sections and a really beautiful 4km final part.

From here there is a cycle path that takes you virtually to Coll Pregón, and then, pushing the bike, you can reach Matagalls.
