La Crosa is an exceptional volcanic building within the Catalan volcanic field. The violence of its explosions, due to the interaction of magma with groundwater, opened a large crater 1,250 meters in diameter, built below the original level of the terrain. These dimensions make it the largest in the Iberian Peninsula and one of the largest in Western Europe. Although there is no precise dating, there is no doubt that the eruption of the Crosa is quite recent, of a few tens of thousands of years at most.

The itinerary begins after kilometre 9 of the GI-533 road from Girona to Santa Coloma de Farners, at the car park of the Guilloteres area. Inthe car park there is an informative ceiling. Next to it begins an itinerary surrounded by wooden fences that allows us to access in a viewpoint with very good views over the crater and the Gironès and La Selva region.

From the viewpoint you have to go back on the same path to the parking, where we can start the itinerary to the crater crossing the road by a basement step. After 100 meters, we take the first road on the left and we start the descent. We follow the flags that take us inside the crater. At the end of a descent we take the sidewalk on the right, without abandoning the path inside the crater. The entire descent allows us to enjoy the lush holm oaks typical of all the volcanic relays of the region.
We continue on the left bordering a field of walnut trees. At the end of the field, at the right, hides the mine, right where a drainage reservoir of the fields goes underground. We continue the itinerary through the crater. The same path, after turning slightly to the left of a small forest, will take us to the central point of the crater, next to a large pile of volcanic stones. In front of us, we can appreciate the small secondary, horseshoe-shaped crater. This strombolian-type crater formed when explosive activity by evaporation of groundwater ceased. Around it, the volcanic rocks are reddish, as seen on the same path, and sometimes with very curious shapes.

A slightly climb takes us to a small esplanade with a new informative ceiling and good views over the crater. At this point we take the path on the left, gradually climbing up to the top of the crater, to the views already of the road. At this point we have to turn left, following the flags that lead us to the Guilloteres. While following these flags, you get a stretch in the middle of holm oak forests parallel to the road, until we meet the path down to the crater, which you have to go back to return to its starting point.
