Among the distinctive landscape features of Loncopué Department are the limestone formations of Riscos Bayos, the Pehuén forests, and the basalt formations of Chenque Pehuén. The town of Loncopué lies on the banks of the Río Agrio and is part of the Ruta del Pehuén.

Riscos Bayos and Chenque Pehuén

Riscos Bayos consists of unusual limestone formations eroded by rain and wind. The “Altas Torres” formations are arranged in a circle; this arrangement was created by wind erosion over time. A conservation study published in 2024 highlights the relict population of Andean cypress (Austrocedrus chilensis) at Riscos Bayos and its distinctive gene pool.

You can drive to the area around Riscos Bayos. From there, an easy trekking trail leads to natural columns, pillars, and spires. The round-trip distance is about 10 kilometers. Cueva del Balcón (CNCN Q251) is also in the Riscos Bayos area, about 15 kilometers from the town of Loncopué of the same name.

Chenque Pehuén, a natural area with Pehuén forests and striking basalt formations, lies about 30 kilometers from Loncopué. Unlike the limestone formations of Riscos Bayos, which were eroded by rain and wind, the landscape here is shaped by basalt. The two places therefore represent different geological features.

Ruta del Pehuén, Chapel, and Crafts

Loncopué is part of the Ruta del Pehuén and, together with Las Lajas, serves as a stop along the route. The historic Nuestra Señora del Pilar Chapel is located in Loncopué. Traditional crafts made from stone, leather, and wood are part of the town and its surroundings. Artisan Geremías Mardones makes leather goods that reflect Loncopué’s rural tradition.

Every March, the “Muestra Ganadera y Fiesta Tradicional” takes place in Loncopué. It showcases livestock production as well as music, dance, and crafts. If you want to plan your trip around the festival, check the latest event calendar and program before you leave.

Río Agrio and Getting There

Rainbow trout fishing takes place on the Río Agrio and its tributaries, Codihue, Hualcupén, Yumu Yumu, and Loncopué. This activity therefore covers both the Río Agrio and the four tributaries named above.

In connection with the Ruta del Pehuén, National Routes 22 and 40, as well as Provincial Routes 23, 13, 21, and 26, are among the main access roads to Loncopué.
