There is a path leading westwards that goes up the hill through terraced basalt walls until it reaches the Hidden Lagoon. From this path, which
is done on foot, you can have the sight of the valleys of Dulce stream (to the right), of the Agrio river (to the left) and of Caviahue.
We recommend that you follow this way: In Caviahue, take 8 de Abril St. until it meets Volcán Copahue St., going past ISSN Hotel on the way. Then
turn left for about 150m, where you will see an important cabin complex. Right behind this complex, at the foothill of the mountain you
will find the path, with a sign and a yellow arrow that shows the way to go.

Agrio River Cascades
From Caviahue, go along PR 26 for about 500m (to the right), cross a bridge over Agrio river and take a dirt road that borders
the cascades: Del Basalto (3m), Cabellera de la Virgen (20m), De la Culebra (4m)and Del Gigante. The latter is characterized not only for having two waterfalls straddling a basalt block that resembles a face in profile, but also for having a wonderful sight of Copahue volcano.

Path to Copahue International border Landmark
This footpath leads to the landmark at Copahue pass, which sets the territorial division between Argentina and Chile. Along the way, you can
get astounding views of Copahue, Lagunas Las Mellizas (The Twin Lagoons) and Copahue volcano.
Going out of Copahue, go to the end of Arturo Fernández Street. From there on, the trip is taken on foot or horseback. Going along the path for approximately 500m, great views
of Copahue are found to the east. A bit farther, about 1km, you can appreciate the Lagunas Las Mellizas and the northern slope of Copahue volcano. From there, you begin
the way down to the valley of Trapa-Trapa. Going 1.2 km to the northwest, after going past an area of damp green grass, you get to the Landmark Copahue Pass. (This border-crossing point is closed)

The stillness of its waters and its location in a valley with nearby lenga and pehuén forests, provide a frame of exquisite scenic beauty. There is a warm volcanic sand beach on the eastern coast, whereas on the western area there is a gorgeous snowmelt waterfall. Hualcupén and Coliqueo lagoons are among the favourites in Caviahue, especially for the practice of sporting activities like fishing and canoeing.
It lies to the southeast of Caviahue, on lands belonging to the indigenous communities Millaín Currical and Guaiquillán; that is why some houses can be seen on the road, where families live during the summer season.
From Caviahue, take PR 26 towards the neighboring Loncopue. After going along this paved road for approximately 5 km, you will see a sign on the right, showing the access to the lagoon. Turn right and go through the gate. There are 8 km to the lagoon.

Copahue volcano crater and lagoon
The trip lasts a whole day. Visitors reach the foot of the volcano by car or truck and begin hiking up its slope, leading to the still active crater
(2750 m.a.s.l.). Stunning views are present all the way up, not only of Caviahue Lake, but also of surrounding lagoons. From the top, the
view of the Cordillera de los Andes is magnificent, with Lanin, Domuyo and Antuco volcanoes standing out.
Once in the crater, it is difficult not be impressed by its steep walled depression and its glacier of everlasting snow. Smoke, vapor and a strong smell of sulfur come from
deep down the vent. The crater resulted from post-glacial volcanic activity, and contains a lagoon which measures from 2 to 3 hectares and whose water is supplied
by rains and snowmelt run-off. Gas emissions heat the lagoon’s waters to temperatures as high as 20 to 40 degrees, and charge them with mineral substances that result in
the water’s high level of acidity. The lagoon drains to the east and gives origin to Agrio River.
