Cerro Calderón, Mountain summit in Rincón de Ademuz, Spain.

The Alto de las Barracas, wrongly called Cerro Calderón, is the highest summit of the Valencian Community at 1,838 m, 23 m above Penyagolosa. It lies in the Sierra de Javalambre, between the Rincón de Ademuz and Teruel, in Puebla de San Miguel. The upper slopes are rocky with limestone outcrops, scattered pines and creeping junipers.

The summit's official name is Alto de las Barracas; the label Cerro Calderón spread through a 20th-century cartographic error and is still often used. The peak lies on the boundary between the Valencian municipality of Puebla de San Miguel, in Rincón de Ademuz, and the province of Teruel. At 1,838 m it exceeds Penyagolosa by 23–25 m, making it the highest point of the Valencian Community.

The peak is known as Alto de las Barracas; the name Cerro Calderón comes from a 20th-century cartographic error. Walkers pass the Pilón de La Santica, a small shrine holding ceramic tiles with the image of the Virgen de la Cueva Santa, and the ruins of old livestock pens and lambing shelters at El Bisco.

A common route starts at the Ermita de San Roque on the CV-363 north of Puebla de San Miguel, climbing the Loma del Carrascal past the Pilón de La Santica. Signposts give distances: Alto de las Barracas 6 km, then 2.4 km and finally 2.2 km after the Pino Vicente fork. A red-and-white wooden fence bars motor vehicles near the top; the final stretch is flat then gently uphill over limestone.

The name Cerro Calderón is a 20th-century cartographic error; the peak is properly Alto de las Barracas. It tops out at 1,838 m, only about 23–25 m above the Penyagolosa, which is why it holds the roof of the Valencian Community. The summit lies in a flora micro-reserve of the Puebla de San Miguel Natural Park, one of seven such reserves.
