The fageda d'en Jordà – in English: the Jordà beech forest – is a natural reserve that includes a beech forest with unique characteristics in Spain, as it grows on relatively flat terrain, formed by a cooled lava flow from the volcano del Croscat, at an altitude that is not common in the Mediterranean area of the Iberian Peninsula for this type of forest, between 550 and 650 m. It has an area of about 4.8 km² and its floor is made up of lava prominences that can reach more than 20 m in height, which are locally called tossols.

The beech forest is famous because the Catalan poet Joan Maragall wrote a well-known poem in its honor ("La fageda d'en Jordà"). At the main entrance to the beech forest, at kilometer 4 of the road from Olot to Santa Pau, where the Can Serra car park is located, there is a monolith in his honour. The use of motor vehicles is prohibited within the forest, however, there are several walking routes and you can rent a horse or an old horse-drawn carriage at kilometer 7 of the road from Olot to Santa Pau.
