In Natural Park of Ports, the vegetation is thick and splendid, with wildlife and nature in the wild. It is a landscape carved by the action of water and wind, because it is a limestone structure. It rains more than in other areas of the region and the temperature is also cooler. There are black pine, holm oak and large trees, some with their own name and catalogued as monumental trees (such as Lo Parot, in Horta; Pimpoll, near the hill of Miralles; Ramut Pine, in Arnes, or Engrilló yew, in Prat de Comte). The rugged orography allows practice all kinds of adventure sports, among others climbing, in rocks of Benet, rocks of Don or right rock of Valls or Estrets. The ports also offer the opportunity to practice the speleology and penetrate into the Conill coves - where you cross the second largest underground river in Catalonia, Domingo Grau, the Frare or the Piletes.
Other alternatives are canyoning and jumps, such as Sotorres or Ferrassó, or the possibility to swim in crystalline·water and contemplate flocks of Hispanic goats or oxes in pasture.
Horta de Sant Joan, Arnes and Prat de Comte are the towns that take up more space in park. The route of the ports should begin in Mas de la Franqueta. It should leave the car at this point and start walking: the best way to appreciate the beauty and silence of those mountains. There are a number of mountain refuges.
