From the Río Eléctrico Bridge begins the path to Piedra del Fraile. After 2 hours of walking, you will reach the administration of the Estancia Piedra del Fraile. The trail to the Administration is free, once you arrive to Piedra del Fraile you must pay an entrance (not included). This place offers different paths with views of the River and Lake "Electrico".
Please note, that here is the entrance to the Continental Ice through the Marconi Glacier, so it is a path well-trodden by climbers.
