Peñiscola is a town in the province of Castellón, on the Costa del Azahar, in Spain. It's more evident trademark is the impressive castle on the shore, built by the Knights Templar in the 14th century.

The trip takes around 20 minutes.
For people not travelling in summer it may be a good option to travel by train to Vinaroz, just 7 Km further, as the bus connections to Peñiscola are more frequent.

The Castle: The Templar-Papal castle is without a doubt the main attraction in Peñíscola, dominating the view of the beach. The castle has 700 years of history. Built by the enigmatic Knights Templar over the ruins of a muslim fortress, the castle has been one of the residences of the Pope (like the Vatican and the Papal Palace in Avignon), when the antipope Benedict XIII, known as Papa Luna in Spanish, fled from Avignon to Peñíscola.
The entrance costs 2.50 €. Opening times: Monday to Sunday from 9:30 to 21:30 in summer, 10:30 to 17:30 in winter.

Old part: The area adjacent to the castle is where most visitors concentrate. Landmarks include the walls, being the gate of Felipe II the main entrance to the old district; the chapel of the Mare de Déu d´Ermitana or the Santa María church of Peñíscola. El Bufador (the Hisser) is a natural curiosity, a tunnel in the rock connecting with the sea, bringing the noise and even water when the weather is rough.
Puerto Pesquero (Fishing Port): A relaxing way to finish the day is to walk along the fishers when they bring the captures of the day.
Islas Columbretes: Formed by four small groups of islands of volcanic origin, the isles are an archipealago of high ecological interest in the Mediterranean, just 60 Km from Castellón. It is also possible to visit the lighthouse. It's recommended to bring snorkel equipment.
From Peñíscola , motor launches depart from the Fishing Port at 8 am on Saturdays and Sundays to the Islas Columbretes, coming back at 19:00. The trip costs 50 €. (Telefon: 964480200, E-mail: firstname.lastname@example.org).
Serra d'Irta (Sierra de Irta): It's a mountainous National Park located south of Peñiscola often missed by tourists. It offers routes for hiking, mountain-bike, horse and quad. Within the mountains there is a hermitage, Hermitage of San Antonio, from where one has an excepcional panoramical view.
The main one is Playa Norte, 5 Km of golden sand on the northen side of the castle, offering also water activities like sailing or water scooter. In summer it can be overcrowed, but out of season it's often completely empty.
Playa Sur is on the southern side of the castle. Much smaller than the northen one (300 meters), it offers a view of the port and an alternative for rough water when the weather isn't good. The presence of the Nautical Station  allows the practice of diving, windsurf or kayaking among other options.
Playas del Pebret y del Russo are two small sand coves, the only ones located on the Natural Park of Sierra d'Irta. Much more relaxed that the ones in the city center, they offer a better contact with the local flora and fauna.
The caragols punxents (murex snails) are very important for the local cuisine, along other seafruits, fishes, rice and vegetables. Dishes like the all-I-pebre de rape (monkfish in garlic and paprika sause) or the suquet de peix (fish pieces with a light sause and potatos) can be tasted in several restaurants.
